"NFC tag detected" typically appears on your device when it comes into close proximity with an NFC (Near Field Communication) tag. This can happen due to several reasons:
Proximity to an NFC Tag: If your device is near an object with an embedded NFC tag, such as a contactless payment terminal, a smart poster, or another device, it will detect the tag.
Enabled NFC Feature: Your device's NFC feature might be turned on, causing it to scan for nearby NFC tags.
NFC Tags on Accessories: Some phone cases, wallets, or other accessories might have NFC tags for quick actions or identification purposes.
Inadvertent Contact: You might unknowingly be placing your phone near an NFC tag, for example, in a credit card or a transit pass.
To stop getting these notifications, you can:
Turn Off NFC: Go to your phone's settings and disable NFC. This will prevent the device from scanning for nearby tags.
Check Surroundings: Ensure that there are no NFC tags nearby that your device might be detecting.
Remove Accessories with NFC Tags: If you're using accessories with NFC tags, remove them or place your phone away from them.
If you're still encountering issues or if these notifications appear without any apparent reason, it might be worth checking if there's an app or a setting causing the notifications.
