Important! On the Redmi 9C, the NFC module only works when the screen is unlocked. If the phone is locked, contactless payments or tag readers will not be available - this is a security measure from Xiaomi.

Configure contactless payments via NFC

The main use of NFC is to pay for purchases with a smartphone instead of a bank card, which requires you to link the card to one of the payment services. On Redmi 9C, there are three options:

  • πŸ’³ Google Pay – works with most banks, but requires the installation of an official app.
  • 🏦 Mi Pay is a service from Xiaomi, supports a limited list of banks (mainly Chinese and some European banks).
  • πŸ“± Banking applications – many banks (Sberbank, Tinkoff, VTB) have their own solutions for contactless payments.

Let’s look at the example of Google Pay:

  1. Download and install the app from Google Play.
  2. Open Google Pay and click Add Card.
  3. Scan the map with the camera or enter the data manually.
  4. Confirm the addition via SMS or push notification from the bank.
  5. After successful binding, select the default card for payment.

To pay for the purchase, unlock the phone, bring it to the terminal at a distance of 2-5 cm and wait for the beep. 9C no additional fingerprint confirmation is required or PIN-It's enough to unlock the screen, which is different from Xiaomi's flagship devices, which often require biometrics.

πŸ’‘

If the terminal is not reading the card, try to hold the phone to another part of the device (some terminals have a non-central antenna arrangement).

Transfer data and files via NFC + Android Beam

In addition to payments, NFC on Redmi 9C allows you to quickly share contacts, photos or links with other devices, using Android Beam technology (although it is replaced with Fast Share in new versions of Android).

  1. Enable NFC on both devices (sender and receiver).
  2. Open the file you want to transfer (photo, contact, or web page).
  3. Combine the back panels of phones (NFC antennas are usually located at the top).
  4. On the screen will appear a notification Touch to transmit - confirm the action.

Limitations of the method:

  • ⚠️ Transfer speed is low (maximum 424 Kbps), so it is better to use Wi-Fi Direct or Bluetooth for larger files.
  • ⚠️ It only works between Android devices (with iPhone, no exchange is possible).
  • ⚠️ On the Redmi. 9C There is no support for Fast Share, so it is better to use Mi Share to transfer files between Xiaomi smartphones.
Why Android Beam was removed from new versions of Android
Google has abandoned the technology because of its low speed and low popularity, and instead uses Nearby Share, which works over Wi-Fi and Bluetooth, but does not require physical touch of devices.

Use of the NFC-tagging and task automation

One of the most interesting features of NFC is tag interaction, which is small chips that can be programmed to do certain things when you touch a smartphone.

  • πŸ”Š Turning Wi-Fi or Bluetooth on/off when you enter your home.
  • πŸ“± Starting the navigator in the car when placing the phone on the holder.
  • πŸ”‹ Transition to mode Do not disturb at work.

To work with the tags on the Redmi 9C you will need:

  1. Buy NFC-tags (e.g., labels, NTAG213 or NTAG215 AliExpress).
  2. Install a programming application, such as NFC Tools.
  3. Write a command on the label (for example, turn on mobile Internet).
  4. Attach the tag in a convenient place (on the wall, in the car, on the desktop).

Example of setting up a tag to start Google Assistant:

  1. Open NFC Tools and select Tasks β†’ Add Tasks.
  2. In the action list, find Launch the application.
  3. Choose Google (or Google Assistant).
  4. Hold the phone to the record label.

Now, when you touch the tag, the voice assistant will automatically open. On Redmi 9C, this works steadily, but note that some actions (for example, changing system settings) may require root rights.

Comparison of NFC on Redmi 9C with other Xiaomi smartphones

The NFC module on the Redmi 9C is a base class β€” it supports all the basic functions, but inferior to the flagship models in speed and range.

ModelType NFCMax, transmission speedSupport for paymentsFeatures
