The modern smartphone has become a versatile tool that replaces wallets, office keys and travel tickets. Xiaomi device owners often wonder about the availability and functionality of the short-range contactless module in their gadgets. Understanding that the NFC in the phone is what it is in the Xiaomi Redmi 8 Pro, opens up access to convenient payment systems and fast synchronization with accessories. This technology has become the de facto standard for flagships and mid-range devices, allowing data to be transmitted up to 10 centimeters.
The Redmi 8 Pro (often confused with the Redmi Note 8 Pro because of its similarity in name) is an interesting case for parsing the functionality of communication. Users need to clearly distinguish between hardware capabilities and software constraints imposed by the manufacturer or region of sale. In this article, we will discuss in detail the architecture of the module, how to activate it and the nuances of working with payment services so that you can use your gadget as efficiently as possible.
It is important to note right away that having a chip in a device does not always guarantee it will work in your region or with a particular bank. MIUI software has its own features of managing energy saving and access to the antenna. We will look at everything from verifying the physical presence of the module to solving typical connection problems to eliminate any uncertainties when using contactless technologies.
Technical specifications and availability of NFC module
The first step to understanding the functionality of the device is to learn its technical specifications. In the line of Redmi, there is often a situation where apparently identical models can differ in the presence of an NFC module depending on the market. For the Redmi 8 Pro (and the Redmi Note 8 Pro close to it), the situation is as follows: global versions, as well as versions for the Russian market, tend to be equipped with a full-fledged NFC chip. However, in some Chinese or Indian versions, this component may be physically absent.
The module is running at frequency. 13,56 MHz and maintains standards ISO/IEC 14443 A/B and ISO/IEC 18092. This means compatibility with most modern payment terminals and tags.The antenna in Xiaomi smartphones is usually integrated into the back cover or located next to the camera block. The quality of the signal reception depends on the integrity of the antenna wire and the absence of metal obstacles between the chip and the reader.
⚠️ Note: Do not try to disassemble your smartphone to search for antennas NFC, If you don't have the right skills, a leakproof housing or a plume damage can cause the warranty to be lost and the device to fail.
Not only can you check for a chip, but you can also look at the labels on the box or in the documentation. Often, manufacturers put the NFC logo on the packaging or back of the device. If the logo is missing, this does not always mean that there is no module, since the design of the boxes can vary depending on the batch. The most reliable way is software diagnostics through system settings or third-party utilities.
How to check and enable NFC on Redmi 8 Pro
If you're convinced that you have a module, the next step is to activate it. In the MIUI Android operating system, wireless interface management is brought to a convenient center. To get started, you need to go to the settings menu. Open Settings and find the Connection and Sharing (or Additional Features in older versions of the firmware) section. This is where the NFC switch is hidden.
Once the slider is activated, the system will start scanning the available tags. Android Beam is often available in the same menu (although newer versions of Android replace it with Nearby Share), which allows you to transfer files. Security requires that the screen be unlocked or confirmed with biometrics when paying.
- 📱 Go to Settings. → Connect and share and activate the slider NFC.
- 🔒 Make sure that the security menu has a PIN, pattern lock or fingerprint installed.
- 📡 To transfer files, turn on Android Beam or Nearby Share in the same settings menu.
- 💳 Add the card to the Google Pay (Wallet) app to check the health of the terminal.
In some cases, the switch may be inactive (shadowed) This indicates that the module is not defined by the system, or the drivers are not working correctly. Try restarting the device. If the problem persists, you may need to update the firmware to the current version through the About Phone menu.
☑️ Diagnostics of the module NFC
Contactless Payment and Google Pay
The main feature that users activate NFC is contactless payment. On Xiaomi smartphones, the main tool is the Google Wallet app (formerly Google Pay). The setup process is simple, but requires attention to security details. Once you install the app and link your Google account, you will be prompted to add a bank card. The smartphone camera automatically reads the data from plastic, which then needs to be confirmed via SMS or a bank application.
An important aspect is choosing the “primary means of payment.” In the NFC settings (Settings → Connection and Sharing → NFC → Primary means of payment), Google Pay (or HCE Wallet) must be selected. If a SIM card application or other software is selected here, the terminal may not respond to a payment attempt.
| Parameter | Value for payment | Description |
|---|---|---|
| Main annex | Google Pay (Wallet) | Application that is launched when approaching the terminal |
| Screen locking | I'll be sure. | Without a password or fingerprint, payment will not pass |
| Access to HCE | Permitted. | The emulation of the host card must be active |
| Status of device | Certified. | Lack of root rights for banking applications |
When you pay, you don't have to open the app in advance, you just unlock the phone and hold it up to the terminal, and the vibration and the sound signal will confirm the successful transfer of the token, and if the terminal doesn't respond, try changing the angle of the phone or pressing it tighter against the reader.
What to do if the bank refuses to be tied?
Using NFC for data and tag transfer
Beyond payment, the technology is widely used for data sharing and automation, and Android Beam enabled contacts, links and small files to be transferred by simply touching two smartphones. Although Google is gradually abandoning this protocol in favor of Nearby Share (which uses Bluetooth and Wi-Fi Direct), basic reading is a good idea. NFC-The tags remain relevant. You can use special tag stickers to automate scripting.
For example, by buying a set NFC-tags, you can program them through the app NFC Tools. One tag in a car can automatically turn on Bluetooth, trigger the navigator and put the phone in "Do Not Disturb" mode. Another tag by the bed will wake the alarm clock and turn off the mobile network. This turns the Xiaomi Redmi 8 Pro into a smart home control center.
- 🚗 Automation: Launching navigation and Bluetooth in the car.
- 🌙 Sleep mode: turn off notifications and set an alarm clock.
- 📶 Guest Wi-Fi: a tag with a password from the network for guests.
- 🔐 Quick Startup: Opening a specific application or website.
To record the tags, use applications like NFC Tools or Trigger. The process is simple: select an action (write URL, text, commands), hold a clean label to the back of the phone and wait for the recording signal, and then the tag becomes active and will perform the action at each touch.
💡
Useful advice: When you stick NFC-If you tag metal surfaces (like a car body or refrigerator), use special shielding linings. The metal can shield the signal, and the phone can't read the tag without an additional layer.
Typical problems and ways to solve them
Despite the stability of the work, users can face difficulties. A common problem is that the phone stops seeing the terminal or the tag. This can be caused by a tight case. If the case has a metal insert, magnetic fastener or too thick a layer of silicone (more than 3-4 mm), it blocks the signal. Remove the case and check the module.
Another common issue is application conflict, and if you have multiple card emulation apps installed (like a bank app and Mi Pay), the system may be confused about which one to run. NFC And you can force Google Pay to be your primary payment method, and you can also clean up the cache of the Google Play Services app through the App menu. → All applications → Google Play Services → Memory. → Clear the cache.
⚠️ Note: If the firmware has stopped working after the update NFC, Don't rush to bring your phone to the service. Often the problem is solved by resetting the network settings (Settings) → Connection and sharing → Resetting Wi-Fi, mobile networks and Bluetooth, it won't delete your personal data, but it will return network settings to factory settings.
In rare cases, the module may shut down due to overheating of the device. When you use the processor or charge in a hot room, the temperature of the case increases, and the protection system can temporarily turn off the communication antennas. Let the phone cool down, and the functionality will recover automatically.
💡
Most NFC issues on the Redmi 8 Pro are solved by removing the case, rebooting the device, or choosing the right payment app in the settings.
