What does NFC tag detected on cash APP mean?
NFC stands for “near field communication.” It's the technology that allows smartphones and devices like payment readers to communicate, and it enables secure, contactless payments like Apple Pay or Google Pay—transactions that require no physical contact between the payment device and the payment reader.
Here's how to do it: Open Settings > Connected devices. Some Android phones have the NFC option in the system tray menu at the top of the screen. Turn off the NFC toggle switch.
- On your Android device, open the Settings app.
- Select Connected devices.
- Tap on Connection preferences.
- You should see the NFC option. Hit it.
- Toggle the Use NFC option on.
