Nfc tag reader

Hello, sourabh1265.

Thank you for using Apple Support Communities.

iPhone 12 Mini NFC is automatically configured to read NFC signals. If you're having troubles seeing an NFC tag you may need to refer to the manufacturer's manual for additional help. If you're using something like AirTags, you can check out this article: Set up your AirTag using your iPhone, iPad, or iPod touch

If neither of these are the case, let us know in more detail about what you're trying to do with NFC. The more information the better the Community can assist.

Best regards.
