RFID Brings Flexibility to Race-Timing Company

Entry App, a U.K.-based timing service for triathlons and other races, has deployed a system leveraging Portable Technology Solutions' ClearStream middleware to capture automated data regarding the movements of race participants until they cross the finish line.

U.K.-based racing services company Entry App has deployed an RFID-based data-management system for its sporting event-timing services that gives it the flexibility to capture data about each event participant's scores without the need to buy a full hosted solution from another provider. The system Entry App is using consists of Portable Technology Solutions (PTS)'s ClearStream RFID middleware, along with Entry App's own management software, with UHF RFID readers and tags installed at each event. That gives Entry App the flexibility to manage data capture, the company reports, without putting the solution in the hands of a third-party provider at a monthly fee.

Entry App serves the racing community in the United Kingdom by providing timing information for children and adult foot races, bicycle races and triathlons. The firm used LF RFID technology for several years to capture timing data automatically, says founder and director Andy Harsant, but the read range was limited and thus did not provide reliable read rates. The LF readers were installed in finish mats that could miss a read if, for instance, an individual were to jump over or pass around it.

The system provides timing information for foot races, bicycle races and triathlons.
Harsant was interested in longer-range UHF RFID-based solutions, but was skeptical about UHF performance in the presence of the human body's water content, which could reflect transmissions. Although there are timing technology vendors that offer full solutions, he didn't want the costs and restrictions related to such systems. Entry App offers timing software that it provides to its customers, so Harsant sought a way to feed RFID-based data into its own existing software.

The company acquired a UHF RFID reader, as well as antennas and tags, then began testing the technology, but it found a shortcoming in the middleware that captured and interpreted reader data. For one thing, Harsant says, he set the UHF system up for a children's running race with 300 participants, during which the solution captured no fewer than 386,000 reads, which he then had to interpret. The readers could not be controlled remotely, so they had to be kept on at all times, even if no race participants were in the area, unless they were physically unplugged.

A Google search brought him to PTS's ClearStream RFID software, which offered the control of read operation he sought to turn the readers on and off, as well as provide tag moderation, configurable GPO state settings, and tag moderation to manage and control the number of tag reads. The software also offers data-repository choices, such as Microsoft Access, SQL, MY SQL and Oracle. Harsant installed the system for a race in November 2017 and found that it worked well.

Race timing offers challenges for RFID installations that few other users have ever experienced, Harsant says. A typical fixed reader portal might be mounted on a wall via permanent screws, with the antennas adjusted until the proper tag read efficiency was reached, after which it would function properly. At an Entry App installation, the deployment begins more typically at 4 AM on a Sunday, providing personnel with about two hours to get the system optimized and in operation ahead of a race.
