The check antenna on the front side of the Chip2Go can be used to check the chip code of any passive race result transponder.
Simply hold the transponder in front of the check antenna and the chip code will be displayed at the bottom of the display.
If 2 or more transponders of the same code are detected then "Number x 2" will be displayed.
If 2 or more transponders with different codes are detected then "multiple tags" will be displayed.
