[[chip timing|RFID for timing races]] began in the early 1990s with pigeon racing, introduced by the company [[Deister Electronics]] in Germany. RFID can provide race start and end timings for individuals in large races where it is impossible to get accurate stopwatch readings for every entrant.{{Citation needed|reason=See talk page|date=July 2021}}

In races using RFID, racers wear tags that are read by antennas placed alongside the track or on mats across the track. UHF tags provide accurate readings with specially designed antennas. Rush error,{{Clarify|reason=|date=January 2021}} lap count errors and accidents at race start are avoided, as anyone can start and finish at any time without being in a batch mode.{{Clarify|reason=|date=January 2021}}

The design of the chip and of the antenna controls the range from which it can be read. Short range compact chips are twist tied to the shoe, or strapped to the ankle with {{Avoid wrap|[[hook-and-loop fastener]]s}}. The chips must be about 400&nbsp;mm from the mat, therefore giving very good temporal resolution. Alternatively, a chip plus a very large (125{{nbsp}}mm square) antenna can be incorporated into the bib number worn on the athlete's chest at a height of about {{convert|1.25|m|ft|abbr=on}}.{{Citation needed|reason=See talk page|date=July 2021}}

Passive and active RFID systems are used in off-road events such as [[Orienteering]], [[Enduro]] and Hare and Hounds racing. Riders have a transponder on their person, normally on their arm. When they complete a lap they swipe or touch the receiver which is connected to a computer and log their lap time.{{Citation needed|reason=See talk page|date=July 2021}}

RFID is being{{When|date=January 2021}} adapted by many recruitment agencies which have a PET (physical endurance test) as their qualifying procedure, especially in cases where the candidate volumes may run into millions (Indian Railway recruitment cells, police and power sector).

A number of [[ski resort]]s have adopted RFID tags to provide skiers hands-free access to [[ski lift]]s. Skiers do not have to take their passes out of their pockets. Ski jackets have a left pocket into which the chip+card fits. This nearly contacts the sensor unit on the left of the turnstile as the skier pushes through to the lift. These systems were based on high frequency (HF) at 13.56{{nbsp}}MHz. The bulk of ski areas in Europe, from Verbier to Chamonix, use these systems.<ref>{{cite web|url=http://cliqology.com/2010/09/epic-mix-skiiers-and-snowboards-social-media-dream/|title=Epic Mix – Skiiers [sic] and Snowboarders Social Media Dream|date=2010-09-07|access-date=2013-09-22}}</ref><ref>{{cite web|url=http://snowboard-mag.com/content/vail-resorts-launches-epic-mix-39814|title=Vail Resorts Launches Epic Mix &#124; SNOWBOARD MAGAZINE|archive-url=https://web.archive.org/web/20100904085254/http://snowboard-mag.com/content/vail-resorts-launches-epic-mix-39814|access-date=2020-03-01|archive-date=2010-09-04}}</ref><ref>Kinsella, Bret.

The [[National Football League|NFL]] in the United States equips players with RFID chips that measures speed, distance and direction traveled by each player in real-time. Currently, cameras stay focused on the [[quarterback]]; however, numerous plays are happening simultaneously on the field. The RFID chip will provide new insight into these simultaneous plays.<ref>{{cite web|title=How a pair of microchips could transform football into an intricate dance of data|url=http://www.dailydot.com/technology/nfl-rfid-player-tracking-zebra-technologies/|website=DailyDot|access-date=1 September 2015|date=2015-08-12}}</ref> The chip triangulates the player's position within six inches and will be used to digitally [[broadcasting|broadcast]] replays. The RFID chip will make individual player information accessible to the public. The data will be available via the NFL 2015 app.<ref>{{cite web|title=The NFL has a (RFID) Chip on its shoulder|url=http://news.surgogroup.com/nfl-has-a-rfid-chip-on-its-shoulder/|website=News Surgo Group|access-date=1 September 2015|archive-url=https://web.archive.org/web/20150906105747/http://news.surgogroup.com/nfl-has-a-rfid-chip-on-its-shoulder/|archive-date=2015-09-06}}</ref> The RFID chips are manufactured by [[Zebra Technologies]].
