NFC—Near Field Communication—has created a technology that can eliminate the dreaded lost keys search with these NFC rings.
Many have lost keys or had hands too full to properly open the front door, and these rings eliminate that problem. When you have the ring placed on your finger, all you need to do is put your hand in front of the scanner and your door will open. Also, the NFC rings will unlock compatible smart phones. Once you have the app downloaded, you are able to place the back of your hand on the screen, and your phone will unlock. This technology will help to provide easier ways to access the items we enter the most.
