Owners of budget smartphones often wonder about the presence of contactless technology in their devices. Xiaomi Redmi 9 model has become a real hit thanks to the excellent price-performance ratio, but its functionality is still surrounded by many legends and speculations, especially the NFC module, which allows you to pay for purchases with one touch of the phone to the terminal.
The situation with the presence of this module in the nine is not as clear as it may seem at first glance, the fact that the Chinese giant released the device in several versions, and the configuration depended on the region for which the gadget was intended. Global versions of Redmi 9 (Global) are most often devoid of the NFC chip, while versions for the Russian and some CIS countries (Global NFC) can be equipped with this module, which is why the instructions for inclusion may not work on your device if the chip is physically missing.
In this article, we will take a look at how to determine if there is NFC in your Xiaomi Redmi 9, where to look for settings and what to do if payment fails. We will look at the technical nuances, software verification methods and real alternatives for those who are unlucky with a package. Understanding these differences will help to avoid disappointment and save time on finding non-existent features.
How to check for NFC in Redmi 9 software methods
The first thing you need to do before you try to set up a payment is to make sure you have the hardware. The quickest way is to use the built-in settings search. Swipe down the home screen to open the search bar, and type in the acronym NFC. If the module is present in the system, you'll see a menu item called "NFC" or "Contactless Payments." The appearance of this item does not guarantee that the chip is healthy, but confirms that it is in the firmware.
The second method is more reliable, and it's to view the full specification of the device through the system menu. → The phone. → All the specifications. In the list of technical parameters that opens, look carefully for the line «NFC». If there is no such line or it is inactive, there is a high probability that your particular instance of Redmi 9 does not have a communication module installed in the factory. MIUI It does not display options for missing equipment.
There is also a way to check through the engineering menu or special applications from Google Play, such as NFC Check or Ampere. These utilities read data from sensors and give a report on the status of modules. However, it is worth considering that third-party applications can give false positive results on some versions of MIUI, showing the presence of the chip where it is physically not, relying on the data of the configuration file, rather than the actual response of the hardware.
- 📱 Enter the request in the search for settings and look at the result of the issuance.
- 🔍 Check the list of “All characteristics” in the menu “About the phone».
- 📲 Use specialized detector applications from the Play Market Store.
- ⚙️ Try enabling the function through the notification curtain (if there is an icon).
Instructions for switching on and setting up the module
If the check confirmed the chip, the next step is to activate it. The standard way to turn it on is to lower the notification curtain and find the NFC icon. If it's not on the visible panel, swipe right or tap the edit pencil to add a button. Once the slider is turned on, the phone will start looking for nearby devices and will be ready to emulate cards.
To make payments through Google Pay (or its equivalents) work properly, you also need to configure the security element. In the NFC settings menu, select Security Element. Here you need to select HCE Wallet or HCE Wallet, which allows the phone's software to interact with payment terminals by emulating a bank card.
⚠️ Attention: If, after activation, NFC choice HCE Wallet phone starts to heat up or quickly discharge in standby mode, this may indicate a conflict of system processes or a malfunction of the antenna.
Then you add a bank card. Open the Google Pay app, click Add Card, and follow the instructions on the screen. You'll need to take a picture of the card or enter the data manually, and then confirm the link via the link. SMS-Make sure that the Internet is on when you add it, and the date and time settings have automatic synchronization.

Compatibility table of versions and regions
As mentioned earlier, the availability of the module depends on the regional version of the device. Xiaomi often labels boxes with appropriate stickers, but the easiest way to target the model specified in the settings. Below is a table that helps determine the probability of having a chip depending on the modification.
| Model/Region | Presence of NFC | Note |
|---|---|---|
| Redmi 9 (Global) | Not often. | Basic version for the international market |
| Redmi 9 (Russia/CIS) | Got (often) | Special version for Russia and CIS |
| Redmi 9C NFC | There is. | Separate modification with NFC index |
| Redmi 9A | No. | Budget model without module |
It's important to understand that even within a region, deliveries can vary. Electronics manufacturers often change parts depending on the availability of chips in the global market. So having a feature from a friend with the same phone doesn't guarantee you have one. Always rely on checking your own device.
If you buy a phone with your hands, be sure to check for NFC before handing over money.Sellers may argue that "just need to upgrade," but software can't add a missing antenna module. It's the physical part of the smartphone that's either soldered into the fee or not.
Solving Contactless Payment Problems
There are times when the module is on, but the terminal in the store can't see the phone. The first reason is often the wrong default payment method. Go to the NFC settings and make sure that the default payment app is the Google Pay app or service you use. If there's a "No" or other application, the terminal can ignore the request.
The second common problem is that you have an unlocked bootloader or modified firmware installed. Google's banking apps and services use SafetyNet to check the security of the environment. If the system thinks the phone is hacked, it blocks access to payment functions, in which case the payment will stop working until the stock firmware is returned.
