SI-Cards are small plastic pegs (70*18*3 mm3) which have a electronic chip in one end. The SI-Card is dipped into the hole in a control station in order for a competitor to register that they have visited a location or competed a task. The control station gives an audible bleep and a visual flash to confirm that the process, which takes a fraction of a second, to complete.
Both the time and control station number are stored on the SI-Card. Additionally the time and the SI-Card number are stored in the control station.
