Timing of Athletes in The UWI SPEC Half Marathon will be done using the Rain RFID Technology by the German Business Leader Race|Results provided by Evolution Timing and Event Management Ltd. The disposable ChipTag is a miniature transponder covered by a 1.5mm Foam for protection. This means the Chip can be used under all conditions (wet, dry, cold and hot).
There are no batteries in the Chip. The transponder is passive until moved into a magnetic field, generated by a send antenna. Here the energizing coil produces an electric current to power the chip. The transponder then transmits its unique identification number to a receive antenna. The whole procedure takes approximately 60 milliseconds and is repeated continuously.
