AUTHENTICATION SYSTEM USING NFC TAGS

Exemplary embodiments provide an authentication system for granting access to an access point. The system includes a Near-Field-Communication (NFC) tag, a NFC reader and writer, and an access point coupled to the NFC reader and writer. The NFC reader and writer is configured to read the NFC tag when the access point is activated and the NFC tag is within range of the NFC reader and writer. In a first phase of authentication, the NFC reader and writer is configured to read and analyze data stored in the memory of the NFC tag to authenticate access to the access point. In a second phase of authentication, the access point is configured to receive and analyze a user input, and grant access to the access point based on analyze of the user input and success at the first phase of authentication.
