NFC, or Near Field Communication, is a passive, short-range, wireless technology that allows you to store and transfer information easily to and from Android &amp; IOS devices as well as payment methods like your debit or credit card. Your Tap Top Contact Card Securely holds your contact information, then using NFC technology, copies that data to your new friend's smartphone. NFC is the technology that makes contactless payments possible (like Google Pay &amp; Apple Pay).
