Where to find NFC in Xiaomi Redmi 8: myths and reality

The issue of the availability of the NFC module in the Xiaomi Redmi 8 smartphone has been a fierce debate among users for several years, due to the fact that the manufacturer has released various modifications of the device for different markets, and the components in them may differ. Many buyers, buying a budget device, hope to use it for contactless payment in stores, but face the lack of a corresponding item in the settings menu.

Search for a feature usually starts with Settings → Connection and Sharing, where the switch should ideally be located. However, in Redmi 8 this section often looks empty or completely absent, which immediately suggests hardware limitations. It is important to understand that software enabling a hidden function is not always possible, since it requires a physical chip and antenna to work.

In this article, we will discuss in detail how to determine whether your instance has NFC, where it is physically located inside the enclosure, and whether there is any way to circumvent the limitations, and we will look at software verification methods, technical documentation analysis, and even look inside the device to give a comprehensive answer to this question.

Programmatic verification of module availability

The first step before disassembling a phone or looking for hidden menus is to conduct a thorough software diagnostic. Standard methods of checking in the shell of MIUI do not always give a clear answer, especially if the module is locked at the regional firmware level.

The easiest way to do this is to check the settings section. Go to Settings → Connection and Sharing. If you see an NFC item there, but it's off, it means that the module is physically present. If it's not there, it doesn't mean it's not there yet, it's probably hidden software. You can use special diagnostic codes to do a deeper check.

Open the Phone app and type ##6484##. This will open the CIT (Customer Integration Test) menu. In the test list, find the NFC item. If there is no such item on the list, the probability of a module missing is extremely high. If there is a point, but the test does not pass (writes Failed), this may indicate a software failure or no antenna plume.

⚠️ Attention: Engineering menu CIT Do not change the settings in other sections of this menu, as this may cause sensors or communication modules to malfunction.

You can also use third-party tools from Google Play, such as NFC Check or AIDA64, which read directly from the system about the presence of the controller, and if the application says “NFC not supported” or “NFC hardware missing”, then, alas, your board does not have the necessary chip.

Hardware revision and model differences

Xiaomi Redmi 8 (codenamed olive) came in several versions, and this is where the problem lies: The global version of the device, designed for the markets of Europe, Asia and the CIS, in the vast majority of cases, is not equipped with an NFC module.

But there are versions for China’s domestic market and some specific regional variations where NFC could be installed, not just in the software, but in the motherboard itself, and when buying a used device or a new machine, it’s important to check the specific model specified in the settings.

The main differences between NFC and non-NFC versions are as follows:

• 📱 Board marking: On the motherboard next to the antenna connector, there may be a place for the chip soldering, which in versions without NFC remains empty.
• 📡 Antenna module: In versions with NFC The antenna is often integrated into the back cover or upper body, whereas in conventional versions there may be a plastic cap.
• 💳 Mi Pay support: Official support for payment systems via Mi Pay or Google Pay is available only if you have a certified chip.

It’s also worth considering that even if you try a phone with a Chinese version on a global one, NFC is not guaranteed unless the chip is soldered physically. Conversely, trying to install Chinese firmware on a global version without a chip will not create a module out of thin air.

Physical location of NFC in the case

If software tests have been mixed or you are planning to make a self-modification of the device, it is useful to know where the antenna and chip are physically located. In the design of Redmi 8, the NFC antenna unit is usually located at the top of the housing, directly under the back cover, next to the main camera module.

The antenna is a thin flexible plate (flex train) with a metallized coating, which is often glued to the inner frame or the cover itself. The controller chip is usually soldered on the motherboard in close proximity to the main processor or Wi-Fi/Bluetooth module.

It is worth noting that self-installation of the antenna and soldering of the chip is a complex procedure that requires professional equipment and soldering skills. BGA-It is easier to purchase external components. NFC-Label or change device to model with technology support.

If you still decide to disassemble the phone, be sure to turn off the battery plume before disconnecting any other plumes to avoid short circuit.

Configuring and activating the function

In the rare case that the module in your Redmi 8 is still present (for example, you bought a Chinese version or a rare modification), it must be activated correctly. MIUI looks like this.

First, make sure that the settings include NFC. Then go to Settings → Connection and Sharing → Contactless Payment. Here, the system will suggest choosing the default payment application. To work in most countries, you need to choose Google Pay (or its replacement, for example, Mir Pay in Russia).

For the correct operation of contactless payment, the following conditions must also be met:

• 🔒 Screen lock: The phone must have a pin code, a pattern lock, or a fingerprint scanner enabled.
• 🌐 Google Services: Google Play Services Should Be Installed and Updated.
• 📱 Root rights: Having superuser rights often blocks payment systems for security reasons.

⚠️ Note: If you unlocked the bootloader or obtained a Root-right, payment applications may stop working even if you have a serviceable module. NFC.

After selecting the application, follow the instructions on the screen to link the bank card, usually you need to take a picture of the card and enter the confirmation code, which will come to the SMS from the bank.

Google Pay Problems and Their Solutions

Even with a serviceable module, Xiaomi Redmi 8 users may experience payment problems, most often the error is “failed to make payment” or the app simply does not see the card, this may be due to regional restrictions or blocking by Google.

One common cause is a mismatch between the Google account region and the SIM card region, and problems can arise if the system has modified versions of the applications or lacks the necessary security certificates, in some cases, cleaning the cache of the Google Pay application and re-associating the card.

If standard methods do not help, you can try more complex manipulations:

1. Remove all bank cards from the app and add them again.
2. Check for system updates along the Settings path → About Phone → Update MIUI.
3. Reset the NFC settings to factory settings in the engineering menu (caution required).

Alternative solutions for payment

If it is confirmed that your Redmi 8 is physically missing an NFC module, don’t despair.There are alternative payment methods that don’t require a chip in your phone. The banking sector is actively developing technologies to avoid the lack of equipment.

The most popular method is QR-code payment. Most banking applications (Sberbank, Tinkoff, Alfa-Bank) have a QR-based payment function. You open the bank's application, select this mode, point the camera at the cashier's code and confirm the payment, and this works in almost all terminals that support fast payments (SBP).

You can also use:

• 💳 Plastic cards: The good old method that works always and everywhere.
• ⌚ Smart watches/bracelets: Some wearables have their own independent module NFC They can work in conjunction with the phone without NFC.
• 📲 External NFC-Key fobs: There are devices that connect via a charging connector, but their support by banks is extremely limited and unstable.
