Have you ever wondered why Xiaomiโs smartphone features so often mention support? NFC, But they rarely explain what it actually does to the user, and it's become standard technology for most gadgets today, but it's going far beyond contactless payment. NFC-module in Redmi devices, POCO Mi, what hidden features it opens up, and why its absence may become critical for some users.
Just make it clear: NFC (Near Field Communication is not just a โpayment chipโ but a universal tool for sharing data over short distances (up to 10 cm), which is integrated into the system chip or made as a separate module on Xiaomi smartphones, and its availability depends on the model. 10A or POCO M3 deprived NFC, Xiaomi 14 Ultra or Redmi Note 13 Pro+ Support all modern standards, includingNFC But how exactly does that work in practice? Let's dig deeper.
What is NFC and how it works in Xiaomi smartphones
NFC (Near Field Communication is a short-range wireless communication technology developed on the basis of the standard RFID. Unlike Bluetooth or Wi-Fi, it is optimized for instant connection of devices up to 10 cm away without the need for pairing. NFC usually consists of:
- ๐ก Antennas โ located under the back cover (often next to the camera) and is responsible for receiving / transmitting the signal.
- ๐งฉ Controller: A chip that processes data and manages protocols (e.g, ISO 14443 for cards or NFC Forum Type 4 for tagging).
- ๐ Secure Element - a secure element for storing payment data (in budget models can be emulated software).
It is important to understand that NFC Xiaomi operates in three modes:
- Reading/write โ the smartphone reads data from tags, cards or other devices (for example, scans a business card in format) NDEF).
- Card emulation โ the phone behaves like a contactless card (for example, to pay via Google Pay or transport tickets).
- Peer-to-Peer โ data exchange between two smartphones (for example, transferring contacts or files via Android Beam).
In Xiaomi devices support NFC It's been implemented in different ways, like the Redmi Note 12 Pro.+ chip NXP PN80T, It supports all modern protocols, including MIFARE Classic (for office access) and Felica (popular in Japan). POCO X5 Pro NFC-chip integrated into Snapdragon processor 778G, This saves space on the board, but may limit functionality when updating.
