Why can’t the Xiaomi 15 read the NFC card?

If the Xiaomi 15 cannot read the NFC card, please follow these steps to enable the NFC card-reading reminders and try again:
1. Go to [Settings] APP on your phone;
2. Tap [More connectivity options];
3. Select [NFC];
4. Tap [NFC card-reading reminders] and set it to [All cards].
This will ensure that your device is ready to properly recognize and read NFC cards. NFC (Near Field Communication) allows for simple, contactless data exchange between devices. If the issue persists after enabling the setting, make sure that your NFC card is properly aligned with the device's NFC sensor, and ensure that the card itself is in good condition.
