NFC Xiaomi smartphones: why you need a chip, how to turn on and use as much as possible

Have you ever wondered why Xiaomiโ€™s features almost always mention support? NFC, But 90 percent of users don't even know how to use it, and it's a technology that's no longer exotic, and it's now embedded in budget models like the Redmi Note 12 or the Redmi Note. POCO X5. However, many people still associate NFC Only with contactless payments, while the chipโ€™s capabilities are much wider: from smart home automation to instant file transfer.

In this article, we will discuss all the functions NFC Xiaomi smartphones, from basic to hidden, you'll learn how to set up a chip on different firmware (MIUI, HyperOS, which models support the technology and why NFC It refuses to work even on flagships like Xiaomi 14 Ultra, and also - we will reveal the life hack using the device. NFC-Tags to automate routine tasks that few people know about.

What is NFC in a Smartphone and How Does It Work?

NFC (Near Field Communication is a short-range wireless technology (up to 10 cm) that allows devices to communicate without an internet connection, NFC consumes a minimum amount of energy and is activated instantly โ€“ just simply bring the smartphone to another device or tag.

In smartphones Xiaomi chip NFC It's usually integrated into the motherboard and runs at 13.56 MHz. It supports three major modes:

  • ๐Ÿ“ฑ Active mode โ€“ both devices (like two smartphones) generate their own electromagnetic field to exchange data.
  • ๐Ÿ’ณ Passive mode โ€“ the smartphone reads information from a tag or card (for example, a bank or transport device).
  • ๐Ÿ”„ Card emulation โ€“ the smartphone itself acts as a contactless card (for example, to pay via Google Pay).

It is important to understand that NFC Xiaomi is not just about contactless payment, but it can interact with the chip:

  • ๐Ÿš‡ Transport cards (for example, Troika in Moscow or Octopus in Hong Kong).
  • ๐Ÿ”‘ Smart locks and intercoms (for example, Aqara or Mi Home systems).
  • ๐Ÿ“ฆ NFC-Automation tags (for example, starting Wi-Fi or enabling silent mode when touching a tag).
  • ๐ŸŽฎ Game consoles (e.g. Nintendo Switch for Joy-Con controllers).

What Xiaomi models support NFC: full list

Not all Xiaomi smartphones are equipped with NFC-For example, in the budget series Redmi A or POCO M is often excluded to make the device cheaper. Below is the current list of models with the NFC 2026, divided into series:

SeriesModels with NFCNotes
Xiaomi 1414, 14 Pro, 14 Ultra, 14 LiteAll flagships have a chip. NXP SN100T supportive UWB
Redmi Note 13Note 13 Pro+, Note 13 Pro 5G, Note 13 5GIn the base Note 13 4G NFC absent

Main functions NFC Xiaomi: From payments to automation

Now letโ€™s look at practical use cases. NFC Most users are limited to payments, but the chip is capable of much more.

1. Contactless payments (Google Pay, Mi Pay, SberPay)

The most popular feature is a bank card emulation.

  1. Install a payment system application (e.g. Google Pay).
  2. Add the card through Add the means of payment.
