Lock or Unlock Your Doors with a Tap
You can use an NFC tag to unlock or lock your door. What’s even cooler is that you don’t have to use it just for yourself. If you’re planning an event or inviting people over, they could enter your event or home with an NFC tag. Granted, if you try to do this, make sure you follow the necessary precautions and revoke their access for future use if desired.
