NFC payments systems are a safe way of transferring private data between smartphones and other devices. When used for payments, it securely establishes a phone user’s identity, verifies that the person has the necessary funds to pay for a product or service, and authorizes the transfer of those funds to the seller. For both the smartphone owner and the vendor, this is a quick, convenient, and seamless way to buy and sell goods and services. It completes a typical transaction in about half the time it takes a contactless card.
