Modern smartphones have long since ceased to be just devices for calls, becoming full-fledged digital wallets and passes. Owners of flagship models such as the Xiaomi Mi 8 Pro are often interested in the functionality of short-range wireless communication, known as NFC. This technology allows not only to exchange data by touch, but also to pay for purchases in stores, which greatly simplifies everyday life.
However, despite the availability of appropriate hardware in the device, users sometimes have difficulty in initially configuring or find that the function is disabled by default. In this article, we will discuss in detail the process of activating the module, setting up payment systems and diagnosing possible malfunctions. In the Mi 8 Pro model, the NFC chip is located at the top of the case, closer to the main camera, which is important to consider when using accessories.
We're going to look at not only the standard menu-inclusive methods, but also the hidden engineering options that might be useful to advanced users. Understanding how this module works will help you avoid common mistakes and ensure that contactless payments work smoothly. Let's move from theory to practice and set up your gadget correctly.
Search and activation of the module in the Android system
The first step towards contactless technology is to activate the appropriate switch in the operating system. In the MIUI shell, which is installed on the Xiaomi Mi 8 Pro, settings can be hidden in different sections depending on the firmware version. Most often, access to control wireless interfaces is in the main settings menu or in the notification curtain.
You can use the control center for quick access. Swipe down from top to bottom to open the Quick Settings Panel. If the NFC icon isn't there, click the edit button (usually a pencil icon or three dots) and drag the switch to the visible area, which will allow you to turn the module on and off with a single touch in the future.
⚠️ Warning: If the icon does not light up after the switch is turned on in the curtain or immediately goes out, this may indicate a software failure or physical damage to the antenna.
The deeper path is through the system menu, so you have to go to the settings section, select Connect and Sharing or Additional Features, and that's where the main controls for your smartphone's network interfaces are, and make sure that the switch opposite the NFC label is activated.
💡
To quickly check the module, hold the phone on to any bank card, and if the device emits a characteristic sound or vibration, then the antenna is functioning properly.
Setting up payment systems Google Pay and Mi Pay
The main reason users are looking for information on how to enable NFC on the Xiaomi Mi 8 Pro is the ability to pay for purchases with a phone. To implement this feature, it is not enough to simply activate the module; you need to configure software that will emulate a bank card. In the Android ecosystem, the main players are Google Pay (now Google Wallet) and the branded Mi Pay service.
The Google Pay setup process requires a Google account and a linked bank card. Once you install the app from the official Play Market Store, follow the instructions on the screen. The system automatically identifies the available cards and prompts you to add them to your digital wallet.
- 📱 Open the payment system application and log in to your account.
- 💳 Click the Add Card button and scan the plastic with the camera or enter the data manually.
- ✅ Confirm the card issue via SMS code or a call to the bank.
- 🔒 Install a reliable method of locking the screen (PIN-code, print or pattern lock).
The Mi Pay service, which is pre-installed on the brand’s devices, works similarly but sometimes requires separate activation in the security settings. When paying, try to bring the top of the Xiaomi Mi 8 Pro to the terminal, because that’s where the antenna is located. Don’t press the device too hard, with enough light touch.
Using the Engineering Menu for Diagnostics
If standard on-boarding methods don't work or the module is unstable, an engineering menu will come to the rescue, and this is a hidden part of the system designed to test the hardware by the plant's engineers. The Xiaomi Mi 8 Pro is accessible through a special combination of characters in the Phone app.
Open the dialer and type ##6484##. The CIT test menu will open for you. You will need to find an item related to NFC (often called simply NFC or NFC Test) in the list of parameters, and running this test will test the chip's response to external stimuli without using third-party applications.
The sequence of actions in CIT:
1. Select NFC.
2. Press "Start Test."
3. Bring a card or other phone with active NFC.
4. wait for the message "PASS" or "FAIL".The test results will help you understand whether the problem is software or hardware. If the test shows an error, software resets may not help, but if the test is successful and the payments do not work, you should look for the cause of the conflict in applications or security settings.
Secret codes for Xiaomi
Addressing common problems and conflicts
Even after setting up correctly, Xiaomi Mi 8 Pro users may find themselves in a situation where the terminal in the store does not see the phone, most often due to third-party applications intercepting control of the module, or power saving settings. MIUI is known for its aggressive optimization, which can “kill” the background processes of payment applications.
You need to check permissions for apps like Google Pay or Mi Fit. Make sure they are allowed to run in the background and auto-start. You should also pay attention to the presence of Root rights. If your smartphone has been rooted, payment application security systems can block transactions for data protection purposes.
| Problem. | Possible cause | Method of decision |
|---|---|---|
| Terminal doesn't see the phone | Wrong positioning | Bring in the top of the body |
| Payment error | Lack of Internet | Check the connection to the network |
| The module is off. | Conflict of applications | Safe regime or discharge |
| Fast battery discharge | Continuous search of devices | Disconnect when not in use |
Another common cause of failures is metallic elements in the case. If you use a protective case with a metal plate for mounting in the car or just with metal decor, this can shield the signal. Try to remove the case and check the function again.
Influence of covers and accessories on the signal
The physical environment of the smartphone plays a critical role in the operation of the antennas. Xiaomi Mi 8 Pro has a glass body, which in itself is good for the passage of radio waves, but any foreign objects between the antenna and the reader can be an obstacle, especially for thick silicone linings and cases with metal inserts.
Metal is a serious enemy. NFC-It creates a Faraday cell effect by blocking the electromagnetic field, and if you notice that payment is only with the cover removed or with a strong press, the problem is the accessory. In such cases, it is recommended to use cases made of thin plastic or leather without metal elements in the area of the chambers.
⚠️ Warning: Some car magnetic holders may contain powerful neodymium magnets that can temporarily demagnetize card chips or interfere with the smartphone antenna.
Also, consider that the antenna in the Mi 8 Pro is shifted to the upper edge, so when using ring holders (pop sockets), if they are installed close to the camera, the signal can also deteriorate.
💡
For NFC to work smoothly, it is important to minimize the number of layers of material between the phone and the terminal, especially if those materials contain metal.
Data security with NFC use
Using a smartphone to make payments raises questions about the security of personal data. NFC technology itself has a high level of protection: the connection is only established at a distance of a few centimeters, which makes interception of data on the fly extremely difficult.
Always watch out for which apps have access to the communication module. Attackers may try to install malware that will read data from cards lying next to the phone (although modern cards are protected from this, risk). MIUI Payment applications, as updates often contain security patches.
- 🔒 Use biometric security (fingerprint) to confirm payments.
- 🚫 Do not turn on the “Always Active” mode for NFC, If you don't use it all the time.
- 📲 Install antivirus software from a trusted manufacturer.
- 👀 Watch for notifications about attempts to connect unknown devices.
In case of loss of the phone, it is important to be able to remotely block access to payment functions. Google's Find My Device service allows you not only to find the device, but also to completely clear its data or lock the screen, which will make it impossible to make payments even with NFC enabled.
