The disclosure relates to a method of operating a system, the system comprising a near field communication, NFC, tag, an NFC device associated with a user of the system and a computer, the method comprising: the NFC device requesting a message from the NFC tag; the NFC tag generating a message comprising a representation of a counter value; the NFC tag sending the message to the NFC device; the NFC device generating a request comprising the representation of the counter value in response to receiving the message; the NFC device sending the request to a computer; the NFC device submitting user authentication data to the computer; and the computer executing an operation on verification of the counter value and the authentication data.

Near field communication system

A smart poster system is provided, which includes a smart poster comprising an NFC device, a mobile device for communicating with the NFC device, and a server unit for providing content to the mobile device, wherein the NFC device is arranged to provide the mobile device with an address of the server unit, the address comprising a counter value, which counter value represents the number of executed read accesses to the NFC device. Also, a method for providing a secure communication channel between a mobile device and a server unit in a smart poster system is conceived, wherein the smart poster system comprises an NFC device for providing the mobile device with an address of the server unit, and wherein the NFC device, upon generating the address, incorporates a counter value into the address, the counter value representing the number of executed read accesses to the NFC device. Thereby, the authenticity of both the NFC device and the server unit is ensured.
