NFC in Xiaomi Redmi smartphones: a complete guide to functions and configuration

Have you just bought a new Xiaomi Redmi smartphone and noticed the mysterious acronym NFC in the specs? Or have you been using the device for a long time but never understood what this chip is for? In this article, we will understand what NFC is in Xiaomi Redmi smartphones, how it works, what tasks it solves in everyday life and why its absence in budget models raises so many questions.

NFC (Near Field Communication) is no longer exotic, but is now integrated into most of today’s smartphones, including the Redmi Note, Redmi K and Xiaomi’s flagships. However, many users still don’t know how to use NFC at full capacity, from contactless payments to smart home management. We’ll talk not only about basic features, but also about hidden features that the manufacturer doesn’t always advertise.

We pay special attention to the unique features NFC-Modules in Xiaomi smartphones: support for emulation of MiFare Classic cards, which allows you to use the phone instead of tickets, passes and even some electronic keys. NFC Often limited to payments only.

What is NFC and how it works in Xiaomi Redmi smartphones

• 💳 Contactless payments via Google Pay, Mi Pay or banking applications (SberBank Online, Tinkoff, etc.)
• 🔑 Emulation of cards (travel passes, passes, door keys with MiFare support)
• 📱 Data exchange between devices (Android Beam, fast transfer of contacts or links)
• 🏠 Management of smart devices (NFC-Labels for Automating Home Scenarios)

Unlike Bluetooth or Wi-Fi, NFC does not require devices to pair and works almost instantly — just hold the smartphone to the terminal or tag. In Xiaomi and Redmi smartphones, the NFC chip is usually located at the top of the case (near the main camera), which is important to consider when using.

Technically, the NFC module in Redmi supports three modes: Reader/Writer (tag readers), Card Emulation (card emulation), and P2P (device-to-device data exchange), while Xiaomi often uses chips from NXP (such as PN547 or SN100x), which provide high compatibility with banking systems and transponders.

Xiaomi Redmi models support NFC

Not all Xiaomi Redmi smartphones are equipped with NFC-chips - in budget models, the manufacturer often saves on this module. Below is a table with the devices that are relevant for 2026, where NFC present":
