To set up NFC on your Dell Latitude E7470, you will need to follow these steps:
Make sure that your computer has an NFC reader. The Dell Latitude E7470 has an optional NFC reader that you can purchase as an accessory.
Check if your phone has NFC. Most modern phones have NFC, but you will need to check your specific model to be sure.
Enable NFC on your phone. On most Android phones, you can do this by going to Settings > Connected Devices > Connection Preferences > NFC. On an iPhone, go to Settings > General > Near Field Communication.
Turn on the NFC reader on your computer. On your Dell Latitude E7470, press the "Fn" key and the "N" key at the same time to turn on the NFC reader.
Tap your phone against the NFC reader on your computer. Your phone should now be paired with your computer, and you should be able to unlock your computer using your phone.
If you want to disable the NFC unlock feature, you can do so by going to the "Sign-in options" settings in Windows and turning off the "Use my phone to sign in" option.
I hope this helps! Let me know if you have any other questions.
