An NFC (Near Field Communication) ID card is a digital identification card that uses NFC technology to store and transmit personal information securely. By tapping the card against an NFC-enabled device, such as a smartphone or reader, users can gain access to services, buildings, or digital platforms. These cards are commonly used for access control, employee identification, secure transactions, and even contactless payments. NFC ID cards are highly secure, offer quick and convenient interactions, and reduce the need for physical keys or passwords, making them popular in workplaces, schools, and public services.
