Each transponder has a unique serial number that identifies exactly which competitor is crossing the start/finish line, or any other timing point on a course. Unlike standard RFIDs, Westhold's transponders have an ultra high data rate (1mbit/sec) at HF (3-30MHz) frequencies. Because the high data rate generates many data points, the system is able to determine precisely when a transponder crosses the center line of the start/finish. Recent tests have shown Westhold to be the most accurate system currently on the market. Four transponder types are available: Rechargeable (Yellow) - Charge lasts 7 days. Green light at top flashes the number of days remaining. Fast recharge (max 3 hours, typically 1 hour). Activated-CAR (Green) - A cost-effective unit meant for cars of all types. No charging necessary. Replaceable internal battery (battery life 3 years, depending on usage. Non-use shelf life up to 9 years). Activated-KART (Blue) - A cost-effective unit intended for motorcycles, karts and quarter midgets. No charging necessary. Replaceable internal battery (battery life 3 years, depending on usage. Non-use shelf life up to 9 years). Hardwire (Orange) - Eliminates charging hassle. Hardwired directly to vehicle. Hooks to 12VDC battery. * Prices for transponder only.
