Smartphones are no longer just call devices, becoming universal tools for everyday life. One of the key features that ensures usability is NFC (Near Field Communication), which allows you to share data over short distances. Owners of Xiaomi brand devices and Redmi sub-brand often wonder how to activate this module to enjoy contactless payment or fast pairing gadgets.
Activating this feature allows you to use smartphones as digital keys, subway passes, and of course as a means of payment. However, despite the prevalence of technology, the activation menu can be hidden or malfunction due to security settings. In this article, we will discuss in detail all the steps of activation, configuration and diagnosis of the module on devices with the shell MIUI and HyperOS.
What is NFC and why you need it in a smartphone
NFC technology is a wireless standard that operates over very short distances, usually no more than 10 centimeters. This provides a high level of security, since an attacker will not be able to read your device data just by walking by. In Xiaomi and Redmi smartphones, this chip is used for three main scenarios: emulating cards for payment, sharing contacts or files, and pairing with smart devices.
Many users see this feature as a way to pay for purchases in stores. Indeed, emulating bank cards is the most popular scenario, but the module's capabilities are much broader. You can read information from tags programmed to run certain actions, or use the phone as a digital key to a hotel or office.
⚠️ Note: Not all models of the budget segment are equipped with a module NFC. Before trying to set up, make sure that there is hardware support by checking the specifications of your device on the official website.
It’s important to understand the difference between software emulation and a physical chip. Some applications can simulate how tags work, but it’s the hardware module built into the Redmi Note or Mi board that’s needed to work fully with payment terminals.
Checking for the presence of a module in your device
Before you go into system settings, you need to make sure that your particular device is equipped with the necessary equipment. Manufacturers often release different versions of the same model for different markets, and in some regions the communication module may not be available. The fastest way to check is using an engineering menu or specialized utilities.
You can download the free NFC Check app from Google Play, which will instantly determine the chip's presence and current status when it launches, and if the app reports no support, no software methods can help activate the feature because it's not physically available.
The alternative method doesn't require third-party software installation, just go to the settings and search for a keyword, and if the system finds the appropriate switch, then (hardware) is available.
Below is a table of popular series where this feature is most common, although exceptions are possible depending on the year of release:
| Series of devices | Presence of NFC | Note |
|---|---|---|
| Xiaomi Mi (flagships) | There is. | In all models, starting with the Mi 4 |
| Redmi Note (middle class) | Partially. | Usually in Pro versions and above |
| Xiaomi Redmi (budget) | Rarely. | Only in the top versions of the year |
| Black Shark (Games) | There is. | In all relevant models |

The main ways to activate through settings
The standard way to turn on a feature in the MIUI or HyperOS shell is simple enough, but it can vary depending on the Android version. Most often, the switch is in the notification curtain or in the main settings menu. For quick access, swipe down from top to open the control center, and find an icon that says NFC.
If there is no icon in the curtain, you need to go to the deep menu. Open Settings, then select Connect and Sharing (or Additional Features in older versions), This is the main switch that puts the module into active state.
- 📱 Open the notification curtain and find the icon NFC.
- ⚙️ Go to Settings. → Connection and sharing.
- 🔘 Activate the slider opposite the point NFC.
- 💳 Select the security element for payment (Google Pay, Mi Pay or Pay) SIM-map).
Once activated, the system can suggest selecting the default card emulation app. If you plan to use your smartphone to pay, it's critical to choose the right security element. In most cases, it's HCE Wallet or your banking service.

Contactless Payment and Google Pay
The most popular use case is payment for purchases. It's not enough to just turn on the module to work; you need to configure the security element. In the NFC settings menu, look for Security Element. Here you need to select HCE Wallet or HCE Wallet so that applications can use the phone's chip.
Then you add a bank card, depending on the region and current restrictions, it can be Google Pay, Mi Pay or specific bank applications, and once you add the card to the app, it will become the default payment method.
⚠️ Note: With developer mode enabled or Bootloader unlocked, some banking applications may block the payment function for security reasons.
Sometimes the system asks for confirmation every time you pay, and to make it easier, you can turn off the request to unlock the screen for your payments, although this will reduce the level of protection for your funds, and make sure that the settings choose the Google Pay app as the main touch.

Advanced settings and antenna position
The settings menu has the antenna location setting, which is necessary for the function to function properly when the phone is in the case or lying on the table. If you choose the option at the top, you need to bring the top of the smartphone to read it. If in the center, then the center part.
Incorrectly configuring this setting can cause the terminal to simply not see your phone, even if all other settings are correct.In most modern Redmi models, the antenna is located at the top, so it is recommended to choose the appropriate item.
You can also adjust the response to tags here, so you can prevent the system from automatically opening apps when you read tags if it's uncomfortable, and this is especially useful if you often carry your phone next to your travel tickets or key fob keys.

Problem Solving and Diagnostics
If the feature is on but the payment doesn't go through, the first cause is often dirt or a metal case.The metal shields the signal, making communication impossible.Remove the case and wipe the back of the smartphone with a soft cloth to rule out external factors.
The second common problem is a malfunction of Google Play Services, and try to clear the cache of that service and the app that makes the payment, sometimes by simply restarting the device, which resets the temporary errors of the communication module.
