But many owners still do not know that NFC-A tag in their phone can not only replace a bank card, but also automate routine tasks, manage a smart home, or even serve as an electronic key.
In this article, we will understand what is NFC In practice, without complex technical terms, but with specific examples for Xiaomi devices, POCO And Redmi.

MIUI, And why some users have problems paying with their phones, and we're also going to reveal little-known chips, like using the phone.

What is it? NFC Xiaomi phone: just about the complicated
NFC (Near Field Communication is a ultra-small radius (up to 10 cm) wireless communication technology that allows devices to exchange data with a simple touch or approach. NFC It is usually a separate chip integrated into the motherboard next to the antenna.
The main difference NFC It's from Bluetooth or Wi-Fi, which is the minimum power consumption and the instant connection, so for example, to pay for a phone, you just have to bring it to the terminal. 1-2 Seconds -- no passwords or long pairing, like in the case of a Bluetooth headset, and the data transfer speed is low (up to a few minutes). 424 kbit/s), but for most tasks β from payments to contact transfers β this is more than enough.
In Xiaomi phones NFC-The tag can work in three main modes:
- π³ Card emulation β the phone behaves like a bank card, transport ticket or pass (used for Google Pay, Mi Pay, subway, etc).
- π± Reading / writing tags β the smartphone reads data from NFC-Stickers or write commands to them (for example, for automation).
- π Peer-to-Peer (P2P) β Data exchange between two devices (file, contact, link transfer).
It is important to understand that NFC-The label is not only a hardware module, but also a software binding in the firmware MIUI. For example, in Xiaomi 13T Pro is supported by the function NFC-key to unlock doors, and in the Redmi Note 11 it is not β although the physical module NFC identical.
How to check if there is NFC in your Xiaomi

3. NFC It's on, but it doesn't read the tags.
- π Energy saving mode - turn it off in battery settings.
- π¦ Damaged tag - try another one NFC-sticker.
- π οΈ Failure of the module - perform resetting of settings NFC In Settings β Annexes β Application management β NFC (click "Erase the data").
β οΈ Note: If after the update MIUI NFC If it's stopped working, try rolling back to the previous firmware version, MIUI 13.0.4 for Redmi Note 10 Pro) were bugs with contactless payments.
An application can be used to diagnose hardware problems NFC Check from Google Play, which shows if the phone recognizes others. NFC-The device, and tests the speed of reading / writing.
NFC-Labels and automation: how to make life easier with Xiaomi
Few people know that NFC Xiaomi can be used not only for payments, but also for automating routine tasks, for example, touching a phone to a sticker on a bedside table can be a good way to do this:
- π Turn on night and alarm.
- π Turn off the sound and activate the "Do Not Disturb" modes".
- π΅ Launch a playlist for sleep in Spotify or Yandex Music.
This will require:
- NFC-tags β buy a set of stickers (for example, NTAG213 or NTAG215) on AliExpress or electronics stores.
- Annex for recording β NFC Tools or Trigger.
- Automation application β Tasker, Automate or MacroDroid.
Example of settings:
- Open NFC Tools and select Write β Add entry β Link.
- Enter a special command for Tasker (e.g, tasker://run?task=Night_Mode).
- Bring the phone to NFC-tape-sticker.
- In Tasker, create a task. Night_Mode with the necessary actions (set the night mode, set the volume, etc.).
Now, when you touch the sticker, you start the script.
Other useful scenarios:
- π Car mode β touching the tag in the car turns on Bluetooth, launches the navigator and sends SMS start-up.
- π Smart home β NFC-The sticker at the door activates the Home script in Mi Home (turns on lights, air conditioning).
- πΌ Work Profile β Touching a tag on the table disables notifications from social networks and launches Slack/Telegram.
β οΈ Attention: NFC-The tags can be "encrypted" with a password through NFC Tools Pro so that they can't be rewritten by accident, this is true if the stickers are in public places (for example, on a desktop).

Myth 2: "NFC-Labels may contain viruses"
On my own. NFC-A tag is a passive device that can't execute code, but it can contain a link to a malicious site. Always check what data is written on unfamiliar tags (for example, through a link to a malicious site). NFC Tools).
