Contactless payments through NFC Xiaomi smartphones have become an integral part of everyday life, but their convenience is often accompanied by risks. If the phone falls into the wrong hands, an attacker can use stored cards in Google Pay, Mi Pay or banking applications - and write off funds without the owner's knowledge. Fortunately, Xiaomi offers built-in protection mechanisms that block the use of the device. NFC-transaction.

In this article, we’ll discuss how to properly configure contactless payment protection on Xiaomi devices (including Redmi models, POCO And the flagship series, what are the security implications, and what do you do if you have a system that's not good?

Important: The procedure may vary slightly depending on the MIUI version (12–14) and smartphone model. If your Xiaomi is released before 2019, check for NFC support in specs – on budget devices (such as the Redmi 7A), the module may not be available.

Why you should include contactless payment protection

According to the Russian Central Bank, in 2023, more than 30 percent of bank card fraud is associated with contactless transactions. A smartphone with activated NFC and tied cards becomes a tasty target for thieves, especially in crowded places (metros, shopping centers).

• 🔓 Unauthorized payments in case of loss of the phone - without PIN-Fingerprint or code, the attacker will not be able to pay for the purchase.

• 💳 Cloning cards through vulnerabilities in the protocol NFC (Less common, but possible, with outdated terminals).
• 🔄 Automatic debits in transport or cafes – without user confirmation.

On Xiaomi devices, protection is implemented on two levels:

1. Software lock – the requirement to unlock the screen before payment (configured in MIUI).
2. Hardware locking – disabling the NFC module when the display is off (not available on all models).

⚠️ Note: If you use Mi Pay (Xiaomi's payment service), default protection may be disabled!
