The next generation in RFID timing

The next generation in RFID timing has arrived and is now available for timing races! For 2016, we have two new options for timing events: Race|Result and ChipCard.

Race|Result is a high precision active tag system that is available upon request and is shipped from Colorado. ChipCard is our own system that was developed and customized using RFID technology from Impinj. Both systems are compatible with CrossMgr software.

Race|Result is an RFID timing system designed in Germany, and provides ten times higher accuracy than any other active chip RFID system. Using a higher frequency 2.4ghz signal compared to the 350mhz signal used by other active RFID chips or 900mhz passive systems, the Race|Result system achieves incredible 1/1000 second timing precision.

The Race|Result system also provides increased flexibility through the use of a single timing loop on the ground, which can be extended up to 12 meters (36 feet) to cover even the widest 4-lane finish lanes.

While J-Chip and Race|Result rely on finish times generated by the RFID receiver, ChipCard utilizes the high precision event timer (HPET) in Windows to provide much higher resolution to the ChipCard finish time.

The Race|Result hardware is also supported by CrossMgr, making it the ultimate timing system for any bike race.

In addition to Race|Result and J-Chip active tags, we also provide our own ChipCard passive tag RFID timing.  The ChipCard provides a number of unique advantages over J-Chip and Race|Result active tags:

  • low cost, so there are no fees for lost or missing ChipCards.
  • the racers bib USA cycling license/account number can be assigned and printed on the ChipCard, allowing the same tag to be used at different events.
  • The ChipCard antennas can support very wide finish lines, up to 60 feet across, while active tags are limited to the antenna mat width, currently 24-feet for J-chip or 35-feet for Race|Result.
  • no overhead truss, ground mat or cables are required, so ChipCard can be used for wide finishes or roads open to traffic.
  • used in conjunction with CrossMgrCamera to provide visual confirmation of finishing order through time-stamped finish line photos.
  • there is no battery in the ChipCard, so there is no lifetime limitation on their use.
  • we have 500 ChipCards on hand with bib numbers 100-499 printed on them.
  • we have our own ChipCard printer with the ability to customize and print unlimited ChipCards on request.

    This article is very nice – compares various RFID systems. But I am missing the time precision of passive UHF RFID sytems. What is typical and maximal precision of these systems?

    Thanks,
    Dalibor

    • Generally, passive tag systems have lower precision than active tags, in the range of 0.2 seconds. For bicycle racing, a flat sprint will typically reach or exceed 34mph (50kmh.)

      Conversion facts:
      34mph is 54.7kmh.
      34mph is 598 inches per second or 49.83 feet per second.
      .01 second at 34mph is 6-inches.
      .2 second at 34mph is 120 inches or ten feet.

      While an active tag will assign the same time to two bikes that are within 6-inches at the finish line, a passive tag may assign the same time to two tags within 10 feet at the finish line.
