How to set up payment via NFC on Xiaomi Redmi 9: from activation to first purchase

Contactless payments via NFC have long become the standard for modern smartphones, but owners of budget models like Xiaomi Redmi 9 often face questions such as “Does my phone support this feature?”, “Which wallet to choose?” or “Why can’t the terminal see the phone?”. In fact, Redmi 9 (model M2003J15SC) is equipped with an NFC chip, but it needs to be activated and configured correctly.

In this article, you’ll find step-by-step instructions from checking hardware support to the first successful payment, and also analyze common errors (for example, when the terminal issues “Error 43” or “Device is not supported”). We tested the process on the firmware MIUI 12.5 and MIUI 13 — all the steps are relevant for both options. If your Redmi 9 is purchased in China (the version for the China ROM market), check the presence of NFC in the specifications — some regional modifications are devoid of this chip.

Spoiler: setting up will take no more than 10 minutes, but before the first payment, be sure to check two points: the balance of the attached card must exceed 100 rubles (otherwise some terminals block the transaction) and the phone screen must be unlocked during payment - this is a security requirement of most banks.

Check NFC support for Xiaomi Redmi 9

Before you start setting up, make sure your Redmi 9 is actually equipped with an NFC module. Even within the same model, there can be differences: for example, the versions for India (M2003J15SI) sometimes come without a chip.

The most reliable way is to check through the settings menu:

1. Open Settings → Connections and Sharing → NFC.
2. If there is no NFC, your phone does not support the technology.

An alternative method is to use the AIDA64 app (available on Google Play):

1. Install and launch the application.
2. Go to the System section → Chipset.
3. Check the NFC string – Yes or chip model (e.g. NXP PN54T) should be specified.

⚠️ Warning: If you bought the Redmi 9 on the secondary market, check if the back cover has been replaced. NFC built into the antenna under the lid - if unskilled repair it can be damaged.

Payment services: Google Pay vs SberPay vs Mir Pay

On Xiaomi Redmi 9, you can set up payment through several services, but not all of them are equally convenient.

For most users in Russia, the best choice is Google Pay or SberPay. The first is universal, the second is convenient if you are a customer of Sberbank. Importantly, since March 1, 2026, Mastercard and Visa issued by Russian banks work at Google Pay only through the Mir system - keep this in mind when choosing a card.

If you have a Tinkoff or Alfa Bank card, check the contactless payments section in the bank’s mobile application – some banks offer their own NFC solutions that may be more convenient than universal services.
