Near-field communication (NFC) is a short-range wireless connectivity technology that uses magnetic field induction to enable communication between devices when they’re touched together or brought within a few centimeters of each other.

It was FFTAG intended to be used to transfer files between phones using Android and IOS Beam. Modern services, such as Google Nearby Share, employ NFC to configure wireless services across faster networks like Bluetooth or Wi-Fi direct.

NFC works on top of three crucial innovations in wireless tag readers, cryptographic credit card processing and peer-to-peer (P2P) connectivity to enable various applications.

NFC has several real-world benefits, including the following:

• Increases operational efficiency for payment processors;
• Ensures more security than traditional credit cards for payments;
• Allows users to choose from multiple cards dynamically;
• Difficult to intercept NFC communications from a distance;
• Ease of use for consumers in paying for goods;
• Simplifies access to back-end information;
• Allows simple setup of new connections compared to other wireless protocols.
