Transponders

TRANSPONDER INSTRUCTIONS

Transponder scoring is the official timing and scoring system for GNCC. We use Sport-Tag brand RFID transponders.

Transponders can be purchased or rented. The purchase price is $75 - cash or credit; if you are using credit, there is a convenience fee.

The rental price is also $75, but you get $65 back when you return it at the end of the day. You will be given a receipt along with your transponder to verify your deposit and your transponder number.

To purchase a transponder, see the attendant under the Registration tent adjacent to Rider Services (registration trailer). This is the only place to purchase transponders.

Transponders expire on the expiration date stated on the back of the unit. Please make a note of the expiration date when you purchase it. Expired units cannot be used and you will need to buy a new one upon expiration. If you use an expired transponder, you will risk not getting credit for your laps, especially if the unit goes down during a race. You are responsible for having a current transponder.

To rent a transponder, you have two options: CASH or CREDIT CARD. See the attendant under the Registration tent adjacent to Rider Services.

If you rented a transponder, please return it to the Registration tent at the end of your race day for a $65 return deposit. You must return the transponder in the same condition it was in when you rented it. If it's broken, just plan on keeping it.

Please make sure to return the receipt along with the transponder. Things go much faster if you have the receipt and if you paid by cash! If you secured the transponder by credit card, you need to also bring $10 cash and we will simply return your credit card slip to you.

A transponder rental is $10 (plus deposit) per event. If you don't return it until after the next race, you get $55 back; if you keep it for three events, you get $45 back. You might as well keep it for good after that.

Please don't carry your transponder with you to the Finish Line area. Some riders stop by the Finish Line to watch the racing action, not realizing that the transponder in their pocket will be picked up by the scoring system. This causes a lot of unnecessary confusion with "phantom" hits and drives the scoring team nuts! So just be careful.

Check your transponder expiration date to ensure it’s still good. Transponders are good for two years after activation - not from the date you bought it. So be sure to verify the expiration date on the transponder itself. The last thing you need is for your transponder to expire during a race. You worked hard for those laps and you don’t want to lose them over a bad transponder! Decoding the expiration date can be tricky. It looks like a clock with the year of expiration in the middle and the months on the outside ring, with an arrow pointed to the correct month – sort of like a decoder ring. In this example, the transponder expires November of 2014.
