Rather than physically restraining a person, the optical turnstile uses sounds and lights to alert others to attempted entry by unauthorized individuals. The advent of the Americans with Disabilities Act (ADA) drove optical turnstile development because physical barriers for access were no longer legal for public access due to the fact that persons in wheelchairs or with other disabilities could not use them as access points. For this reason, they are not likely to be used in

temperature scanning, palm geometery, iris scan, and advanced handwave readers. Smartphone credentials that use Wi-Fi, cellular, and
Bluetooth technology are gaining interest for this purpose as well. Besides hygiene benefits of such new credentialing, security is also enhanced in the biometric case by the inability for biometrics to be stolen or shared between individuals.
313:. In parallel, Automatic Systems and others developed barrier type optical turnstiles (speedgates) for the mass transit industry that were eventually adapted and evolved for Class A commercial real estate and corporate HQ entrance control markets. Today there are many manufacturers, based in North America, Europe, China and around the world.

Following the global COVID-19 crisis, new hygiene-oriented credentialing integrations became the focus for pedestrian entrance control manufacturers. Card readers and even some (fingerprint) biometric devices that require contact are expected to be largely replaced by contactless facial recognition,

The optical turnstile products have evolved with technological advances over time. Many security entrance lanes today are optical turnstile portals employing moving, mobile barriers of metal, glass or acrylic in some cases. The barriers can be drop arms, swinging glass, retractable (sliding) glass,

Newest technological offerings in optical turnstiles include climb-over detection software, biometrics and QR code reader integrations inside the cabinet, and built-in elevator destination dispatch screens, often at 45-degree angle. Manufacturers can state their product reliability in terms of MCBF
341:
Interest in turnkey, installed speed gate/speedlane optical turnstile systems rose after 2020 due to concerns with lack of technical trained resources after the pandemic and a general interest for integrators to focus on technology rather than labor. Providers of security entrance control systems

or other materials. The sensing technology has improved to a higher level of security violation detection, as well as to allow for faster throughput. Longer cabinets are sometimes used to increase throughput. Trolley detection is employed to discern between
