Is it possible to install nfs if it is not. What is NFC? What is nfc module

NFC technology in Russia has already matured to the point where you can even pay for purchases at the nearest Pyaterochka with a smartphone. Therefore, many owners of older devices became interested: how to add NFC to a phone without NFC? If you're here for this, we have two pieces of news: good and bad.

Bad news: you can't use NFC to its full potential

Alas, this is the sad truth. If NFC support is not built into your smartphone by the manufacturer, then no household tricks will help you equip it with all the features of this module.

Why? To answer this question, you need to understand what is behind the words "NFC support". First, a special chip must be soldered into the smartphone's motherboard. Secondly, the smartphone case must contain an NFC antenna that will transmit signals from the chip to the outside world. And thirdly, your phone's operating system must be able to receive and transmit data using the NFC protocol.

Agree, if you are not a specialist in radio electronics and part-time programmer-system engineer, adding NFC to a phone without NFC with your own hands is quite problematic. Therefore, the only full-fledged way out is to buy a smartphone with NFC support.. For instance, .

The good news: in part - you can still!

However, not everything is so deplorable. To help those who are deprived of the opportunity to buy a phone, detachable phone accessories come - NFC-enabled SIM cards and detachable NFC antennas.

NFC-enabled SIM cards in Russia are issued only by the Big Three operators - MTS, Megafon and Beeline. But we will focus on the first one, since the solution proposed by it meets our task.

Megafon and Beeline cards are designed for a slightly different purpose: they are installed in phones that already have NFC support and are used for contactless fare payment in transport from a mobile phone account.

But with the help of the service from MTS you can partially use NFC payment options, namely, to pay in transport and in stores, using an MTS-Bank card as a wallet.

What is needed for this?

Issue an MTS-Bank card at the office of a mobile operator, or install an application on a smartphone for free MTS Money and release a virtual one. The application resembles Google Pay.

In addition, you need to purchase a set for contactless payment in the MTS salon: a SIM card with an NFC chip and an NFC antenna. It looks like this:

The SIM card is installed in the phone in the usual way, and a thin flexible antenna is brought out of the case. There is a big limitation here: your phone must have a removable battery. Modern phones with a non-removable battery and a SIM card tray cannot be upgraded like that (however, as a rule, they already support NFC anyway). This is what it looks like assembled:

The antenna can be carefully glued to the back cover so that it does not hang out. That's it - you can replenish your MTS virtual card account, launch the application and pay with it in stores and the metropolitan metro.

Despite the fact that almost everyone has access to information, not every mobile device user knows what NFC is in a smartphone, what this technology is for and how to use it.

how nfc works

NFC is a computer technology that has gained fame, allowing you to make purchases in stores and pay for services without money (cash) and a bank card. This is a new and almost secure method of contactless payment. The communication interface is used in a smartphone. To pay, it is enough to bring a smartphone with the installed module to the terminal.

The principle of operation of the NFC module in a smartphone is the same as that of plastic cards with a wireless function.

There are several well-known ways to use the NFC interface in a mobile device. Most often, people use it to make contactless payments. A bank card is attached to the mobile device. It is difficult to intercept bank card data due to the small range of this module. More dangerous in this case are left unattended, lost or unlocked smartphones.

The payment transaction is carried out in several stages:

• Purchasing and activating a card with PayPass technology.
• Installing the application of your issuing bank.
• Activate NFC technology on your mobile device.
• Attaching the card to the smartphone, starting the data reading procedure.
• Receiving from the bank in SMS a pin code for making transactions.
• Payment for goods and services using a smartphone and a payment terminal.

There is another, less common way to exploit NFC technology. With the help of the module, you can exchange data. Files are transferred from one mobile device to another, and a special Android Beam application acts as an intermediary. But it is inconvenient to exchange data in this way, since the transfer rate is low and the range is minimal. The method is suitable for sending text messages, but no more.

The third way to use the technology is to write and read labels. The label is assigned to certain actions, such as sending a message, calling a contact, or accessing the Internet. The function is suitable for people seeking to optimize their personal time and automate their everyday life.

How to set up nfc for contactless payment by phone

The NFC setup consists of the following steps:

1. Module activation. The user enters the “wireless networks” settings section and puts a checkbox opposite the NFC name.
2. Agent choice. The user has the opportunity to select and install the application of the issuing bank of his card for data transfer.
3. Module binding. The user brings the device closer to the card with PayPass technology until the signal works.
4. Confirmation. Receiving an SMS code for transactions.
5. Usage. Payment for goods and services in terminals with NFC technology.

Is it possible to buy a separate nfc module for the phone

The purchase of a separate contactless communication module for a telephone is possible in the form of several solutions. Together with a mobile device, you can use a special SIM card or antenna. The SIM card works in the same way as its counterparts. It is produced by mobile operators and is installed in a smartphone in a special slot. A SIM card opens up all the possibilities of contactless transactions using a mobile phone at the level of Apple Pay or Samsung Pay.

NFC antenna- a radio device that performs the functions of an NFC module, but the user will have to install it on his smartphone on his own. The antenna is glued to the SIM card and installed under the cover of the phone. On a model with a non-removable cover, modules are more difficult to install, but theoretically possible.

What are nfc tags

Recording and subsequent reading of labels is necessary to automate everyday tasks. Tags are similar to QR codes. Approaching the tag, the smartphone reads it using the NFC module and performs encrypted tasks. For example, it opens a video on YouTube, email, SMS or calling a contact from the phone's address book.

A smart ring or bracelet with an NFC function is a new development from Chinese engineers, suitable for smartphones running on any operating system. The bracelet can be chosen for any hand size (the same with the ring). The device weighs quite a bit and fully supports NFC technology. The functions of the processor, for example, in the band 3 nfc model are performed by a special chipset. Thanks to the chipset, the smart bracelet helps the smartphone to exchange data via a contactless channel, while maintaining the necessary security. Data on a device can be overwritten hundreds of thousands of times.

The bracelet stores payment data, notes and other personal information. Viewing information is easy - just bring the bracelet to the smartphone screen. The bracelet will instantly establish a connection with the phone and unlock the screen, and will also be able to perform the function of a "hot" button. For example, when you bring the bracelet to your smartphone, the camera, the Internet or the social network application will instantly open.

How to find out if the phone has nfc

The NFC icon, if the smartphone has this module, can be found in the settings menu. On an Android device, you need to:

1. Open the settings menu.
2. Open the "wireless networks" section.
3. Read the list of networks supported by the device. If there is no network in the list called NFC, then the smartphone cannot exchange data using this technology.

Is nfc technology safe? Will the money be stolen?

People who have been using contactless bank cards for a long time do not need to be explained what NFC technology is. This payment method is safer than the standard method of activating a PIN card in the terminal, since no one sees the code. Even after the smartphone is stolen, an attacker will not be able to withdraw more than 1,000 rubles from the card due to universally applicable restrictions on the amount limit in contactless transactions.

Some media have reported that the attackers have developed terminals that are used in crowds, quietly debiting money. But this is only possible if the smartphone is not locked.

Tip: if the fraudster still managed to write off the money illegally, the account holder can always contact the bank and ask employees to track the movement of funds. The attacker's account will quickly be found and the money will be returned to the owner if he (the fraudster) has not yet spent it.

Programs for creating NFC tags

There are already many separate applications for creating NFC tags, but their number is constantly growing. The following specialized programs are in great demand:

• ABA NFC. The program creates standard labels for various purposes.
• WiFi Tap. The program quickly connects the device to a wireless network without entering a password.

Initially, Near Field Communication technology ( NFC) has gained maximum distribution as a technology for making contactless payments. You can use a smart card with an embedded NFC chip as a public transport ticket, as a payment card in retail establishments, as a smart business card or as a contactless key card.

However, in recent times, this technology has been increasingly used in devices such as smartphones and tablets: almost all major manufacturers have begun to equip their mid-range and high-end models with NFC adapters.

What is NFC?

If we translate the name of the Near Field Communication technology from English, we get the phrase "near field communication", which can be deciphered into ordinary language as wireless communication over short distances. Thus, we see that two NFC-enabled devices can communicate with each other when they are nearby. And indeed - the "range" of NFC is only a few centimeters.

In mobile devices, NFC technology can be used for various purposes. You can, for example, turn your phone into a virtual bank card, use it as a pass to a pool or a business. You can also quickly exchange files and links, and even, using special applications, read and write information to programmable NFC tags or NFC smart cards.

In the Android operating system, NFC support appeared in Android 4.0 Ice Cream Sandwich - its built-in Beam feature allows you to share files between devices.

Why do you need NFC if you already have Bluetooth?

As you remember, NFC is most often used when paying for various goods or services, and in this case, Bluetooth is not quite suitable. Firstly, because of its large range (there is a possibility of interception of your payment data). And secondly, the connection between two NFC devices, unlike Bluetooth, occurs almost instantly.

Does your device support NFC?

Not all phones and tablets have NFC adapters. Does your tablet support NFC? How to check if it exists?

Some manufacturers, such as Samsung, place the Near Field Communication logo directly on the battery of their smartphones, while others, such as Sony, place the NFC logo on the device.

However, the easiest way to check for an NFC adapter in your phone or tablet is through its settings menu:

Go to the settings menu of your Android device

In the "Wireless networks" section, click "More ..."

Here you should see the NFC settings items:

NFC activation

If your tablet or phone has an NFC adapter, you need to allow it to be used to exchange data between other NFC devices.

Go to Settings -> Wireless networks -> More...

Check the box "allow data exchange when combining the tablet with another device"

This will automatically turn on Android Beam.

If Android Beam doesn't turn on automatically, just tap on it and choose "Yes" to turn it on.

When Android Beam is disabled, it limits the ability to share NFC data between smartphones or tablets.

Sharing data using NFC

Once you have activated NFC, you can use it to transfer data. For successful data exchange between tablets and phones, please note the following:

Both the sending and receiving devices must have NFC enabled and Android Beam enabled.

None of the devices should be in sleep mode or have a locked screen.

When you bring two devices close enough to each other, a beep will sound to let you know that the devices have found each other.

Do not separate the devices until the data transfer is complete and you hear a successful beep.

Data transfer via NFC

Place the back panels of the devices against each other.

Wait until confirmation appears that both devices have found each other and the sender's screen shows "click to send data":

Click on the screen and the data transfer will start:

You will hear an audible confirmation, both at the beginning and at the end of the data transfer.

Application Sharing

With NFC, you cannot share APK files. Instead, the sending device sends the other device a link to the app on the Google Play Store, and the recipient opens a page on the Store offering to install it.

Web page sharing

Just like in the previous case, the web page is not transferred from one device to another, but only a link to it is exchanged, which the recipient tablet or phone opens in its web browser.

YouTube video sharing

Again, when sharing a YouTube video, there is no transfer of the file itself - just a second device will open the same video on the YouTube site.

Using NFC tags.

In addition to sharing information between tablets and phones, you can use your device to read (and write) data from NFC tags and smart cards equipped with an NFC chip.

NFC chips are small enough that they can be embedded anywhere - in business cards, bracelets, product labels, stickers, price tags and other items. They can contain information about a person, a URL, information about a product, and even commands that your phone or tablet will have to execute when you tap these tags.

To read data from NFC tags (or to write information to them), you will, of course, need a special application.

For example, using the Yandex.Metro program, you can find out how many trips are left on a one-time Moscow Metro card, and the NFC App Launcher program will allow you to program your phone or tablet to perform certain actions by placing the relevant information in an NFC tag.

Conclusion

Most of today's Android phones and tablets are already equipped with NFC adapters, but so far this feature has little demand and its use is still limited, mainly by the ability to quickly share content and contactless payment for services. However, in the future, NFC can penetrate into all areas of our lives, sometimes even completely unexpected ones.

The NFC module was originally intended for one-touch payments. A SIM card with a built-in chip can be used both in shops, municipal transport, and as a contactless "master key" or business card. This technology has also been used in tablets and smartphones.

Leading manufacturers equip gadgets of the middle class and above with special adapters that allow you to instantly transfer data and perform other operations. Despite this, many users do not know what the NFC function is in the phone and how to use this device.

Android devices have been equipped with special chips since the release of OS 4.0 Ice Cream Sandwich. The NFS module is designed to communicate tablets, phones located at short distances from each other.

NFC technology in smartphones provides the user with the following features:

• Quickly share various files;
• Use the gadget as a pass to various organizations, institutions;
• Make contactless payment with one touch;
• Store or read data in a specific format.

Many advanced users are interested in what NFS is in a smartphone and whether the user really needs this function, because all gadgets are equipped with Bluetooth.

NFS technology is most often used for payments, which means that the signal range is minimal. The connection between the phone and the device is completed in seconds, providing complete security, which cannot be said about Bluetooth.

Does the device support NFS interface

Not all modern gadgets have such a chip. On Android, a simple Bluetooth can be installed, which does not allow you to use the device to perform secure transactions.

How to find out if there is NFC in a smartphone in order to enjoy all its benefits. You can check the availability of this function through the settings located in the menu of the tablet or phone:

• Go to Android settings;
• In the line "Wireless networks" click "Advanced";
• Enter the NFS settings menu.

Having found the desired function, the user can activate it or set restrictions. To do this, in the same tab, you must:

• Check the box next to "Allow data exchange";
• Wait for the Android Beam program to turn on;
• If the function does not start automatically, click on Android Beam, then confirm the action.

On a note! NFS in Android phone- this is not a separate means of transferring files, other information, but a command device. Data is exchanged via wireless communication. The chip sends a command to activate the Internet and transfer information.

Which smartphones have NFS

If the user knows what NFC is for, then he can easily use this module when performing various operations. Almost all modern gadgets are equipped with this technology. Here are some examples:

• iPhone, starting with the 6S model;
• Samsung Galaxy S3, LG latest models and Xperia X from Sony.

Other manufacturers can also please with the presence of an advanced device. The NFC function on Android allows you to carry out various operations quickly, safely, which is its main advantage.

Possible options for using the NFS module

The module can operate in several basic modes. Namely:

• Active. Both smartphones are equipped with a special chip.
• Passive. Only one gadget model is used.

On a note! The chip operates in several modes. The first is used to exchange information between smartphones or planets. The purpose of the second is a “pass” or a card, when passing in the subway, buying a bus ticket.

Contactless payments

In the plastic card emulation mode, the NFS chip makes it possible to pay for services and goods at terminals. The most common Android Pay services, for iPhones - Apple Pay. The module installed on the smartphone allows you to hide the data of the cardholder, thereby securing the operation.

How to pay via NFC from an Android phone:

• To make a payment, you will need a paypass-enabled card;
• Download a special application;
• Enter the personal page in the main menu;
• Select the item NFS;
• Attach the plastic to the back of the smartphone so that the module reads the data it needs.

Using the NFS option, the owner of the gadget will be able to transfer funds for a completed purchase with one touch.

Public transport fares

With certain settings, the NFS system can be used as an electronic ticket. Support for the latest technology will allow passengers of underground and surface transport to use the chip much faster when passing through turnstiles or recording a completed trip.

Exchange of information using modern technologies

After activating the NFS, it can be used to share files. To send information, the user must adhere to a certain algorithm.

How to use NFC on a smartphone:

• On gadgets, activate NFS and Android Beam;
• Both mobile phones must work and be unlocked;
• When the smartphones are next to each other, the user will hear the corresponding signal, which informs that the gadgets are in the field of view.

Attention! You can separate devices only after the transfer of information is completed. The user will know about it by the appropriate signal.

Instant information scanning

Reading with an electronic chip functions by scanning a barcode - a label located on the media. They are gradually replacing paper codes and contain not only information about the manufacturer, but also the composition, shelf life, and other data.

Reading individual labels

The principle of its operation is similar to barcode scanning. But in this situation, it is not the camera on the mobile phone that is used, but the sensor located under the cover. This feature is especially useful in household use.

To create tags, the user needs to install an application that can be downloaded from the Play Market. The smartphone owner will be able to fix a certain task on their own: “create a message”, “send a letter”, “make a call”.

Most popular apps:

• ABA NSF. Used to create simple symbols.
• Device to enable the wireless Internet without a password (the smartphone is attached to the gadget connected to Wi-Fi);
• Smart Tag Maker. The application is suitable only for the owner of Sony gadgets.

On a note! Such labels are passive. They do not need to be powered to store data. They have a small volume, necessary only to consolidate the team. These labels are calledTecTiles. To scan them, it is enough to bring the smartphone, after which the task set by the user will be immediately completed.

What to do if there is no NFS on the phone

Most smartphone owners are wondering how to use Android Pay without NFC. Mobile operators have developed SIM cards with a built-in signal transmission module.

What to do if the phone does not support NFC - the first option:

• Buy a special SIM card;
• Put it in the slot on the smartphone;
• The chip is automatically activated.

On a note! It should be noted that the dimensions of the signalGSMare different and depend on the format on a particular device.

What to do if there is no NFC on the phone - option two:

• Purchase an external device for making contactless payments;
• Next, you need to read the instructions on how to install NFC in a smartphone - most often it just needs to be fixed on a SIM card;
• Place in tray.

Attention! One minus - this method is suitable for gadgets that have a removable cover. Non-separable models and mobile phones with side slots cannot be equipped with an external device.

Advantages and disadvantages of modern technology

The main advantage of the NFS module is low energy consumption, affordable cost, safety and ease of use. But before you activate this function, you need to study certain nuances.

Like all devices, the NFC module has some disadvantages:

1. Small range. This gives some inconvenience when using this technology. On the other hand, it provides maximum security. The owner of the smartphone will not be able to accidentally pay for the goods, set a command.

1. Uncontrolled development of modifications for the NSF. Gadget manufacturers Haomi and Sony are trying to improve the process of transferring information. They make their own parts that only work with their smartphones or tablets. To enjoy all the benefits of the module, the consumer will have to buy mobile phones of certain brands, as well as install applications only from these developers.

On a note! Developers are gradually trying to eliminate some of the shortcomings and make various improvements to their technology.

If the user does not know how to connect NFC to a smartphone or finds it difficult to do this, it is better to contact a specialized center for help from experienced craftsmen.

The NFS module allows you to make purchases with one touch and carry out other types of transactions. If your smartphone does not have this function, you can purchase the appropriate chip or SIM card. To ensure proper security, the owner of the phone will have to enable screen unlock by fingerprint or PIN code - there is no other way out.

NFC (Near Field Communication) - one of the types of wireless communication that operates at a very close distance - all new and modern smartphones, as a rule, are on board even when they leave the factory. However, from old devices or low-budget devices, the presence of an appropriate chip can not be expected. What advantages does the NFC chip bring with it?

• First of all, it makes sense to use NFC for everyday activities, since the user must repeatedly change certain settings every day, for example, adjust the volume, activate Bluetooth or WLAN, turn GPS on and off.
• NFC automates changes to settings because you can store the relevant information in so-called NFC tags. Then you simply read the desired tag with your smartphone and the saved settings take effect.
• NFC is also excellent for automatically launching applications, also in combination with an NFC tag on which you can save a command, for example, turn off Bluetooth and WLAN in the evening, while opening the alarm clock application at the same time.
• NFC can also be used as a business card or greeting card. In the first case, you can save all the necessary personal information on your NFC card, to which you can attach links to a website or social networking channels. The other user can then simply hold their smartphone over the NFC card and get all your contact information directly.
• It makes sense to send a personalized digital greeting card primarily in combination with a real card. So, for example, you can not only wish a friend a happy birthday in a letter, but also put an NFC tag in an envelope, with which the recipient can watch a video on YouTube or a couple of pictures saved in a cloud service.
• For all the fans of order, NFC also offers one extremely interesting option: for example, when you move, you can stick tags on boxes so that you can then view its contents with just a touch of your smartphone. Also, tags are great for keeping order in the basement or attic.
• And, after all, NFC makes it possible to pay wirelessly through a smartphone, even if payment systems such as Android Pay or Apple Pay are not available.

Installing NFC - the first opportunity

In general, you have three different options to equip your smartphone with NFC functionality. Of course, none of them can completely replace the NFC chip integrated by the manufacturer, since such an upgrade is only possible with limitations.

• Perhaps the easiest option is to simply stick an NFC tag to the back of your smartphone or, if it's not too thick, hide it under a case.
• Then the phone will be able to control and manage NFC tags in a completely normal way, since the tags can "talk" to each other. In addition, this method has one advantage: in this form, the function does not consume battery power.
• Of course, no other settings can be applied since the system cannot connect to the NFC tag.
• For this reason, you will not be able to use applications such as "NFC Tools" because they need system access to the NFC chip.
• Of course, with the help of other devices equipped with an NFC module, you can read information from the NFC tag on your smartphone.

Installing NFC - the second opportunity

The second option to upgrade the phone with the NFC function has been around for several years, but it is extremely effective.

• You are using an SD card that has an NFC chip built into it. Of course, your smartphone must have a Micro-SD card slot for this option to be considered at all.
• The advantage of this method is that the system can access the chip and then it becomes possible to use the above applications.
• The supplier of this kind of Micro-SD card is a company called "Moneto".
• But a mobile payment service provider such as DeviceFidelity, for example, offers similar solutions that allow you to not only pay, but also use the rest of the NFC functionality.
• However, there are often problems with the availability of the MicroSD card, so this possibility is perhaps difficult to implement.

Installing NFC - the third possibility

Installing NFC: NFC Cover

And finally, there is still the option of self-replacing the back cover of your smartphone.

• Be careful: following this procedure, you can completely void the warranty for your smartphone, especially if you damage something inside the device.
• If you still decide to replace the back cover, then the main task is only to install the back cover with an integrated NFC chip.
• After that, the system will gain access to the chip, and therefore the full range of NFC functionality will become available to you.
• Whether such a back cover exists for your smartphone, you can check, for example, on Amazon.com.
• Removing the back cover for each device is carried out differently. Depending on the model and manufacturer, you may even need an additional tool.
• Given all this, you should only start replacing the back of your smartphone if you know exactly what will need to be done and take into account what difficulties may arise along the way.
• Therefore, this last method is not the most comfortable, but for smartphone connoisseurs it may be worthy of attention.
