A system including a sensor, a computing device and a Wireless Access Point (WAP). The sensor in response to receipt of an initiation signal, via a first communication channel, from a relatively proximal computing device, is arranged to generate and store first security information and to transmit, wirelessly via a second communications channel, a first message comprising information representing at least a part of the first security information. The WAP, which is remote from the sensor is arranged to receive and store the first message. The WAP is arranged to generate second security information and to transmit wirelessly to the computing device, via a third communications channel when the computing device is within range of the WAP, a second message comprising information representing at least a part of the second security information. The sensor is arranged to receive at least the second message via only the first communications channel.
