Now, to go shopping, you no longer need to take paper money or a credit card with you; all you need is an iPhone. Recently, owners of Apple devices have acquired useful function Apple Pay, which allows you to pay your invoice using a smartphone.

Unfortunately, some users are complaining that apple pay is not working for them. In this case, the previously tied visa card or mastercard will be completely useless. Let's learn more about the function itself and its possible malfunctions.

1. Make sure your iPhone is older than model 5.
2. There is not enough money in the account.
3. The credit card PIN code has been changed.
4. Module or antenna malfunction.
5. iOS glitches.
6. Problems with the terminal.
7. iPhone is outdated.
8. The card was not added correctly.

How to fix

1. Reboot your device.
2. Force reset your network settings.
3. The time or date is set incorrectly.
4. Change the region to any other region other than your country of residence.
5. Remove and re-link the card.
6. Malicious or antivirus programs are installed on the system.
7. Other software glitches.
8. The NFC chip has failed or the antenna of the module has fallen off - only repair by service.
9. Reinstall or update iOS.

The technicians jokingly answer that it will be enough to replace the iPhone. Jokes aside, but if Apple Pay doesn't work for you, it's better to contact service center. If the NFC antenna is to blame, then before you know it, it will be replaced. But don’t worry about problems with the module; the repaired chip works at the level of the factory analogue.

Even if you own an iPhone 10, you can't protect yourself from unexpected software failures. Well, due to a defect in the software, the main functions of the NFS suffer, which begin to incorrectly transmit information from the device.

How to use Apple Pay

Let's start with the fact that Apple Pay appeared on the iPhone relatively recently. Therefore, you should not be surprised by owners of smartphones from the Apple brand who are just getting acquainted with new technology payment.

It is supported on all devices equipped with NFC, such as the iPhone 6S or Watch series. But it happens that payment does not always behave correctly. This can be attributed to problems with operation contactless payment due to the cover or malfunction of the terminal itself.

By the way, compared to credit cards, where you need to enter your PIN to confirm payment, on the phone this function is carried out using touch id. But the payment will only go through if your fingerprints are entered into the device’s memory.

However, before you go shopping, you should link your card. To do this, use the wallet program. Here, for your convenience, you can confirm the credit card (you will receive a code via SMS), which you have already paid for in iTunes.

Another undoubted advantage of the application is its convenient management, which allows you to delete all cards from Wallet at any time. Just remember, shop when iPhone help this is really cool!

What is NFC and why is it needed?

A possible reason why apple pay stopped working could be a malfunction of the NFC chip. However, before looking at troubleshooting methods, let's figure out why it is needed.

First of all, this is a communication module. It is used to read or transmit data. It may appear as an indication key, a travel card, or credit card. Now even subways and buses have equipment installed to work with this technology.

Data transmission occurs via an NFS antenna. And to confirm consent to exchange data on the latest models of gadgets, a fingerprint is enough. After which, a connection to the terminal occurs. This technology is also available on iPhone SE.

Therefore, before purchasing an “i-device”, you need to check the functionality of the NFC, because if it is damaged, difficulties may arise when connecting to the payment terminal.

It is necessary to remind you that iPhone models up to and including 5S do not work with the contactless system. For owners of outdated equipment, it is possible to connect an Apple Watch equipped with an NFS chip.

Crashes and problems in iOS

User reviews are heard from everywhere who claim that iOS is no longer as stable as it used to be. And this is true, because an overabundance of additional functions leads to periodic violations in the software, which could cause the apple pay setup to fail.

So, here are a few ways to solve the problem if paypass stops functioning properly:

• The device needs to be rebooted.
• Force a network settings reset (Settings - General - Reset - Reset network settings).
• If you notice a glitch when paying, go to Wallet app, delete and re-link the card.
• When you touch your phone to the terminal and it doesn’t react at all, you should try changing the region of your smartphone to the one where contactless payment works. For example, by selecting the country Great Britain (Settings - General - Language and region).
• As a last resort, if the above methods did not give any results, reinstall iOS, or at least update the firmware. Then, check contactless payments without resorting to recovery backup phone settings.

You can find out whether the Apple Pay function is working only after purchase. In this case, the device writes ready as soon as the money is debited from your account.

The NFC chip has failed

If you discover that apple pay is not working, you should think about the health of the NFC chip. In most cases, the module itself always remains in good working order, which cannot be said about periodic problems with the antenna contact of the smartphone. As a result, we have problems with performance when making any purchase.

The bracket itself, responsible for signal transmission, is located in top corner housings. Another reason why NFC may come from weak signal This is dust or debris that has gotten inside the device. To solve this problem, it will be enough to disassemble the phone, remove everything unnecessary and tighten the bracket bolts, thereby eliminating the “undercontact”.

Let's say the chip is working, the garbage has been removed, but the gadget continues to show payment completion errors. Then, once again, pay attention to where the NFC module is located in the iPhone 6; perhaps the case is preventing it from making a payment. After all, it can directly influence the operation of the module. So-called “bumpers” and aluminum cases have a particularly negative effect on signal conductivity.

Conclusion

So, as we found out, if your Apple Pay stops working, the problems may come from the software or hardware. In some cases, payment does not always work due to the presence of a thick case on the phone.

It must be remembered that the technology began to be supported only from the 6th iPhone models, earlier 5, 5S, 4S, 4 do not support contactless payment for goods and services.

Another option why the payment does not go through could be the terminal itself. And also don’t discount the possibility that it’s all to blame Apple settings Pay, in particular - the credit card was not added correctly or the Pin code was changed.

Users working with contactless payments based on NFC technology may encounter the message “NFC tag type is not supported” when trying to make such a payment on their Android smartphone. The problem often mentioned is observed on Samsung smartphones (in particular, the Samsung Galaxy family), which is due to Samsung’s refusal to support the “MIFARE Classic” NFC tags on most of its devices. In this material I will outline the essence of the problem that arose with the indicated labels, and also provide possible options her decisions. To find out, go to the corresponding article.

Why "MIFARE Classic" tags are not supported on Samsung Galaxy

When you enable NFC (near-contact communication) technology on your device, "MIFARE Classic" tags are often used. Such tags are based in part on the ISO/IEC 14443-3A standard, and use their own (proprietary) encryption algorithm. Since NXP (the owner of the MIFARE Classic technology) is in no hurry to share the rights to the MIFARE Classic technology with manufacturers of other chips, access to the MIFARE Classic tag memory is possible mainly on NFC devices with a chipset from “ NXP."

This usually means that you will not be able to access MIFARE Classic tag data using devices that do not have a built-in NXP chipset ( system service NFS filters "MIFARE Classic" tags and does not notify applications of their presence). Fortunately (or unfortunately) for owners of Samsung gadgets, Samsung has decided to block the “MIFARE Classic” technology on many of its devices, and when you try to use it, you will see a message stating that “NFS tag type is not supported on the specified device " As a result, you won’t even be able to detect these tags on specialized applications running on Samsung phones.

System message about the lack of support for “MIFARE Classic” in one of the smartphones

As an exception, some of Samsung gadgets may include chipsets from NXP. In particular, " Samsung Note 3" has an NXP PN544 NFC controller and, accordingly, supports MIFARE Classic. But " Samsung Galaxy S6" contains an NFC controller from Samsung "S3FWRN5P", and, therefore, does not support (or rather, blocks) the operation of "MIFARE Classic".

What to do if "NFC tag type is not supported"

The mentioned problems with NFS tags arise mainly among Muscovites - holders of the Troika transport card when they try to top up the card balance using the popular My Travel Card application or other similar software. If you are the owner of a Samsung gadget, then in most cases the problem with tags is of a hardware nature (lack of a chipset from NXP), which makes it impossible normal work with NFC technology.

Nevertheless, there are a number of Samsung devices that support MIFARE Classic technology. In particular, these are devices such as (the list is incomplete and may vary):

• Galaxy Note II
• Galaxy Nexus I9250
• Galaxy S III
• Galaxy SIII Neo
• Core DUOS
• Galaxy S5 G900F.

If you have one of these gadgets, and, nevertheless, you encounter the error text “NFC tag type is not supported,” then it is recommended to do the following:

Conclusion

The existing problem with NFS tags, which exists on devices of the Samsung Galaxy line, is due to Samsung blocking the MIFARE Classic technology from the manufacturer of NFS chipsets NXP. In such a situation, you can try to programmatically remove this message (for example, using the method described in

Nowadays, more and more manufacturers are installing an NFC chip in smartphones. The unique technology makes it possible to exchange information with other devices. Interface wireless communication provides a low data transfer rate and is characterized by a relatively short range. However, small dimensions and low power consumption allow it to be placed in small electronic devices.

Since the NFC interface is just a base, application developers and manufacturers mobile devices OnePlus has to create special operating scenarios. Therefore, when combining different models technology may conflict. NFC technology is used not only for data exchange, but also for reading and writing tags and making contactless payments. Payment is made after attaching a bank card to the smartphone.

During use, the owner may encounter a problem when NFC does not work on the OnePlus phone. First, you need to make sure that the device supports near-field communication. It may also be called P2P or Reader/Writer. The necessary information about the device is in the instruction manual.
