If you’re the owner of a Xiaomi Redmi Note 7 and you’re trying to figure out where the NFC module is hidden in that smartphone, you’re not alone. Even though it came out in 2019, the location of the contactless chip is still a bit of a confusion, because the Redmi Note 7 has several modifications, and not all of them are NFC-enabled. Moreover, even in versions that support the technology, the chip can be installed in an obscure location.
In this article, we will not only show you where you are physically located. NFC-The module in Redmi Note 7, but also explain how to correctly identify, activate and check for health. You will learn which versions of the smartphone support contactless payment, how to distinguish them from models without contact.

Which Redmi Note 7 versions support NFC?
The first thing to understand is that not all Xiaomi Redmi Note 7s have NFC. The manufacturer has released several versions of this model, and only a few of them are equipped with a contactless communication module.
- 📱 Redmi Note 7 (Global/EEA) — version for the European market (EEA) necessarily NFC. This is the most common modification with support for contactless payments.
To determine if your smartphone has NFC, check:
- Box marking: Look for an NFC label or contactless logo.
- Phone settings: go to Settings → Connections and Sharing → NFC. If there is no item, there is no module.
- Technical specifications on the Xiaomi website by model number (you can find it in Settings → About phone → Model).
Where is the physical location NFC-chip in Redmi Note 7?
If your Redmi Note 7 is an NFC version, the contactless chip is located at the top of the back cover, next to the main camera.
- 📍 Under the glass panel, the chip is soldered into the motherboard and closed with the back cover. You can't see it from the outside, but the range of the antenna is concentrated in the upper third of the body.
- 🔍 Next to the top speaker – if you attach the phone to the payment terminal, the optimal touch point is 1-2 cm below the camera.
- ⚠️ Don't confuse with antennas. Wi-Fi/4G — They are located on the sides of the body and have no relation to the NFC.
Important: in the Redmi Note 7 NFC-The chip has no separate external contact (like the iPhone), the antenna is integrated into the case, so for contactless payments, it is enough to bring the phone to the terminal with either side of the top. However, most terminals read the signal better if the screen of the smartphone is turned upwards (the camera is away from itself).
Why can’t NFC work even if you have a chip?
To find the NFC coverage area accurately, do a simple test:
- Activate the module in settings (Settings → Connections and Sharing → NFC).
- Open a contactless payment app (like Google Pay or Mi Pay).
- Gently swipe your phone through the payment terminal, starting at the top of the back cover and gradually moving down.
- Remember the position at which the terminal emits an audible signal or flashes – this is the NFC active zone.

##4636##In the menu that opens, select Phone Information and check for NFC status.
If NFC is not determined, possible causes:
- 🔧 Software failure – try resetting the network settings (Settings) → System system → Resetting settings → Resetting Wi-Fi, Mobile Network and Bluetooth).
