Abstract: 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.
