2.Selecting a service for payments: Google Pay vs Mi Pay vs SberPay

The Redmi Note 9 has three main ways to pay by phone, each with pros and cons:

  • πŸ“± Google Pay is a universal service that works with most bank cards (VTB, Tinkoff, Alfa-Bank, etc.) Supports card tokenization, which increases security.
  • πŸ’³ Mi Pay is a Xiaomi wallet, which is not officially supported in Russia, but can be installed bypassing regional restrictions.

4. Features of payment in transport and shops

Contactless payments via Redmi Note 9 work not only in stores, but also in public transport (for example, in the Moscow metro or buses with Strelka terminals).

In transport, terminals are often set up to read Troic cards or Mir cards. If you have another bank card tied, payment may not pass.

  • πŸš‡ Link the virtual Troic card in the My Traveler app (available on Google Play).
  • πŸ’° Use the map Mir – it is guaranteed to work in Russian transport.

In stores, problems are usually related to:

If the terminal is not responding to the phone, try turning off and re-enable NFC in the settings. Sometimes this resets temporary communication errors.

5.Contactless payments security: how to protect money

Paying by phone is convenient, but requires a heightened focus on security.

1. Use a lock screen. Without it, anyone can unlock their phone and pay with your card. PIN-code, fingerprint or face recognition in Settings β†’ Lock screen.

2. Turn off NFC when you're not using, and this will prevent accidental debits if your phone is near the terminal, and only activate the module before you pay.

3. Set up payment notifications. In the bank app, activate SMS or push alerts for each transaction, so you will immediately know about unauthorized write-offs.

4. Do not store card data in unreliable applications. Use only official services (Google Pay, SberBank Online) and download them from trusted sources (Google Play).

⚠️ Warning: Fraudsters often send phishing links to "Google Pay update" or "Mi Pay activation." Never enter card details on suspicious sites! Official services do not request CVC-code PIN via email.

What to do if your phone is lost or stolen?
1. Immediately block cards via the bank app or hotline. 2. Delete card details from Google Pay remotely via the web version of the service. 3. Use the Find Device feature (google.com/android/find) to lock or reset your phone. 4. If the phone is stolen, report to the police - this will help to recover money in case of fraudulent transactions.

6. Alternative methods of payment by phone

If the NFC on your Redmi Note 9 doesn’t work or you prefer other methods, consider these options:

  • πŸ“± QR-codes – many banks (Tinkoff, Sberbank, VTB) support payment QR. It is enough to open the bank application, select the option "Pay by" QR" and scan the code at the checkout.
  • πŸ”’ Samsung Pay – Although it is a Samsung service, it can be installed on Xiaomi via Samsung Pay APK. However, work is not guaranteed and the bank card must support the technology. MST (magnetic).
  • πŸ’» Apple Pay via emulation – it’s technically possible to run Apple Pay on Android via a virtual machine, but it violates Apple’s rules and can lead to account locking.

QR-codes are the most universal way, like at Sberbank Online to pay for the code. QR:

  1. Open the app and select a map.
  2. Click Pay by QR.
  3. Hover the camera over the code on the terminal screen.
  4. Confirm the payment with a fingerprint or PIN-code.

Minus. QR-payments – they require an unlocked screen and an open bank application, which is less convenient than the NFC. But they work even on phones without a contactless module.
