Smartphones are no longer just call devices, becoming universal tools for everyday life, where wireless is a key role. Owners of the popular Redmi Note 8 Pro often wonder how to activate contactless payment to use the gadget in stores and transport. Despite the fact that the device was released a few years ago, it remains relevant thanks to powerful hardware and support for modern technologies for data transmission over short distances.
The MIUI activation process has its own nuances that distinguish it from pure Android. In global versions of MIUI firmware, the NFC module is located at the top of the case, next to the main camera. The right configuration of this component allows you not only to pay for purchases, but also quickly pair devices or read information from tags. In this article, we will discuss all the steps necessary for the full operation of the technology, and also answer frequent questions of users.
Before you go into settings, you need to make sure that the chip is physically present in your device, as some regional modifications could come without it. If you purchased the phone officially or from trusted resellers, most likely all the components are in place.
Check the availability of the NFC module in the Redmi Note 8 Pro
The first step before any setup should be hardware verification. Xiaomi Redmi Note 8 Pro was originally designed with support for Near Field Communication technology, but in the secondary market or when buying refurbished devices, there may be exceptions.
You need to go to Settings, then select Connect and Sharing (or additionally in older versions of MIUI). If there is an NFC switch in the list of options, then the module is physically installed and recognized by the system.
There is also a software method of diagnostics through the engineering menu or special applications from the Google Play store. Utilities like NFC Check or NFC Tools are able to read the specifications of the chip and show its ID. If the application says "NFC not supported", then software activation is impossible without replacing hardware components.
⚠️ Note: If the switch is in the settings menu NFC is, but it immediately turns off or burns in gray, this may indicate a conflict of system processes or damage to the antenna module after a fall.
For owners of devices purchased in the Chinese market with subsequent flashing, the situation may be more complicated, in such cases, the module may not be determined due to incompatibility of regional settings firmware. IMI-dialer code ##6484##, where the Near Field Communication checklist is also included.
Activate NFC through MIUI settings
Once the hardware part is confirmed, the software interface should be activated correctly. In the MIUI shell, the wireless protocols are managed in a separate unit that can be accessed in different ways. The standard algorithm of actions involves using the main configuration menu of the system.
Open Settings and find Connection and Sharing. In the list that opens, move the slider opposite the NFC label to the active position. Immediately after activation, the system can suggest selecting the default payment application, a critical step for correct payment operation.
An alternative way to get to the right option faster is to use the control panel. Swipe from top to bottom across the screen to open the notification curtain, and find the NFC icon. If the icon is not on the first page, swipe left to edit the buttons and add the necessary shortcut. This will allow you to turn the module on and off in one click, which is convenient for saving battery power.
It is important to note that in some versions of the firmware, the item may be called Contactless Payments or hidden inside the “More” menu. If the standard paths do not result, use the built-in Settings Search by typing the “NFC” request into the search bar at the top of the screen.
Google Pay and other payment systems
The main reason users activate this module is the ability to pay for purchases with a smartphone. To work with payments, you need to set up an emulator app. On Xiaomi devices with global firmware, the de facto standard is Google Pay (or its successor Google Wallet), although Mi Pay is actively used in some regions.
The process of adding a card begins with the installation of the corresponding application from the Play Market store. After launching the program, you will need to log in to your Google account and click the "Add Card" button. The smartphone camera automatically reads the data from the plastic, after which you must confirm the information and accept the bank's terms.
- 📱 Open the payment system application and log in.
- 💳 Click Add Card and scan the plastic or enter the data manually.
- 🔐 Check out the verification through SMS-bank-call.
- ⚙️ In the settings NFC Select the Security Element as"HCE Wallet or purse HCE".
The key is to choose the security element. NFC Find the Security Location (or “Default Payment App”). To work Google Pay, select the option. HCE Wallet, if it's chosen here"SIM-card, contactless payment through banking applications will not work.
☑️ Pre-payment checks
Once the card is successfully attached, the phone is ready for use in terminals, and when it is brought to the reader, the device must vibrate and produce a characteristic sound.
Use of Mi Pay and alternative services
Owners of Redmi Note 8 Pro devices may find that Google Pay is unavailable or unstable in their region, in which case the company’s own service, Mi Pay, comes to the rescue. This service is built directly into the system application “Security” or “Mi Credits” and often requires fewer resources to work.
To activate Mi Pay, you need to go to the Security app, find the Mi Pay section, and add a card. The process is similar to setting up Google Pay: scanning, code confirmation. The advantage of this method is deeper integration with the MIUI shell, which sometimes allows you to bypass the restrictions imposed on third-party applications.
However, it is worth considering that the list of supported banks for Mi Pay may be narrower than for Google Pay.In addition, the service depends on the region selected in the Mi Account. If you change the region in the phone settings, the service may stop showing or work correctly.
| Parameter | Google Pay / Wallet | Mi Pay | Applications of banks |
|---|---|---|---|
| Integration | System (Android) | Deep (MIUI) | Separate annex |
| Supporting banks | Wide. | Limited. | Depends on the bank. |
| Requirements | Google services | Mi Account | Internet |
| Stability | Tall. | Medium | Tall. |
There are also applications from specific banks that are able to emulate the card themselves, using access rights to the card. NFC-In the phone settings, you'll need to select "Use the default app" and specify the specific bank, which is less convenient, because every payment may require manually running the application.
Work with NFC-tagging and automation
The Near Field Communication technology in the Redmi Note 8 Pro goes beyond payments, and allows you to interact with programmable tags that can perform various actions on your phone, opening up vast possibilities for automating everyday tasks without installing complex software.
Free utilities can be used to record labels, for example, NFC Tools, they can be used to write to a chip. URL-Web site address, contact information (vCard), text or command to launch the application, and if you hold the phone to such a label, you will perform a predetermined action.
- 🏠 Home scenario: the label at the entrance automatically turns on Wi-Fi, puts silent mode and starts smart light.
- 🚗 In the car: tag on the torpedo includes Bluetooth, navigator and music.
- 🔒 Scenario "Sleep": a label by the bed alarm clock and puts the phone in "Do not disturb" mode".
MIUI also has a built-in tagging functionality that is in the Scanner app or in the NFC settings, and you can assign an action when you detect a certain type of tag, which is especially useful for organizing workspace or quickly accessing frequently used functions.
Can I clone the intercom keys?
When using labels, it is important to remember the recording format. Text or URI is enough for simple tasks, but complex scenarios may require NDEF. Make sure that the tags you buy or use are not password protected from writing, otherwise you will not be able to change their content in the future.
File transfer and device pairing
Another feature that often goes unused is fast data transfer and pairing, and although NFC transmission speeds are low, it is ideal for instantaneous connection between devices, after which data can be transmitted over Bluetooth or Wi-Fi Direct.
Android Beam (or its counterpart in the newer versions of Android, Quick Share/Nearby Share) allows you to transfer contacts, photos and links between phones with a simple touch of the back panel. To do this, both devices must be enabled with NFC and Bluetooth.
In addition to file transfer, NFC makes it easier to pair with accessories. Headphones, speakers and fitness bracelets Xiaomi often support fast connection. Instead of a long search for a device in the Bluetooth list, just hold the phone to the accessory, and the connection will be established automatically.
⚠️ Note: When transferring files, make sure both devices are unlocked.For security reasons, Android will block receiving data from unknown sources if the screen is turned off.
It is worth noting that for efficient transfer of large amounts of data, it is better to use Mi Drop technology (now part of Xiaomi Share), which uses the technology of the company. NFC It's only for handshakes, and it's a high-speed Wi-Fi transmission, which allows you to transmit video. 4K within seconds.
Troubleshooting and troubleshooting
Despite the reliability of the Redmi Note 8 Pro, users may experience problems with the module, most often complaining that the phone stopped seeing cards or tags, and in most cases, the problem is solved by software methods without contacting the service center.
The first thing to do when crashes is to check for system updates. Xiaomi regularly releases patches that fix driver errors. Go to Settings → About phone and click on the MIUI version to check for updates. Also helps to clean the cache of the application "NFC Service" in the application menu.
💡
If the NFC stopped working after a fall, carefully check the area around the main camera. The antenna module is located there, and a strong impact could have moved the contact plume.
If the phone doesn't see the payment card, try re-releasing it in the bank's app. Sometimes tokenization (the process of creating a digital analog of the card) goes wrong the first time. Delete the card from Google Pay and add it again, following the instructions on the screen carefully.
In cases where the module does not turn on at all, resetting your network settings can help. This action will not delete your personal photos or contacts, but will return all network settings (Wi-Fi, Bluetooth, NFC) To the factory values. To the reset: Settings → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.
💡
90% of NFC issues on the Redmi Note 8 Pro are solved by rebooting the device, updating the Google Play Services apps, or re-associating the card in the payment app.
If the software methods don't work, and the module isn't detected even in safe mode, there's a high probability of hardware failure, which could be the failure of the chip itself or the antenna break, which requires skilled repair in the service center.
Impact of NFC on Autonomy and Safety
Many users are wary of turning on NFC because of the alleged high battery consumption. However, the current chips installed in the Redmi Note 8 Pro consume minimal energy in standby mode. Active power consumption occurs only at the time of reading, which lasts a fraction of a second.
In terms of security, the technology is considered to be quite secure, with a range of only a few centimeters, making remote data interception impossible, and when you pay through Google Pay, your real card number is not transferred to the terminal, but a virtual token is used.
- 🔋 Battery impact: Less than 1% per day on standby.
- 🛡️ Data Protection: Using Tokenization Instead of Real Card Numbers.
- 🚫 Remote reading: impossible due to short range (up to 5 cm).
However, it is recommended to follow basic digital hygiene rules: do not store scans of documents and passwords on your phone in plain form (PIN-code, fingerprint), as payments can be made without additional authorization if the phone is unlocked.
