On this page, please note the following:
Do not apply the transponder anywhere else on your helmet, except on the visor, unless your visor cannot accommodate it. In such cases, place the transponder behind your front number plate. Avoid placing the transponders on your vehicle, your person, your clothing, or any other location on your helmet besides the visor.
Here's how to render your RFID tag ineffective (which is not desirable).
The RFID Transponder Tag is an adhesive strip containing an electronic circuit. It is crucial to mount it correctly to ensure its detection when crossing the finish line, as there are various ways to improperly handle it. For instance, if the tag is positioned too close to conductive metal, commonly found inside helmets, it can disrupt the tag's frequency and render it unreliable. Simply follow the steps provided, and you'll be in good shape.
Firstly, DO NOT PLACE AN RFID TAG OVER ANOTHER RFID TAG. This practice, known as "stacking tags," will render both tags ineffective. If you have multiple tags on your visor, ensure that there is at least 1/2" of space between them.
