NFC For Access Control

What is NFC for Access Control?

NFC, or Near Field Communication, is a short-range wireless communication technology that allows devices to exchange data when they are in close proximity, typically within a few centimeters. In the context of access control, NFC enables secure and contactless authentication, allowing users to gain entry to physical or digital spaces by simply tapping an NFC-enabled device, such as a smartphone, card, or key fob, against a reader.

NFC operates on the principles of Radio Frequency Identification (RFID) but is designed for more interactive and user-friendly applications. Unlike traditional access control methods, such as keys or magnetic stripe cards, NFC offers enhanced convenience and security, making it a preferred choice for modern access control systems.
