Technology is evolving rapidly, and many new technologies are changing traditional workflows. Mobile payments and biometric methods are now widespread. Visitor access is also changing: face recognition systems are being adopted as an alternative to access cards and fingerprint readers.
1. Faster and More Convenient
Convenience is a key advantage of face recognition systems. Capturing, analyzing, and matching facial data can be completed in a very short time. The process is contactless, so users do not need to present a card or touch a scanner, which simplifies operation. Compared with other contactless identification methods, face recognition offers additional benefits; for comparisons of several contactless approaches, see market analyses on contactless recognition technologies.
Recognition response time for face systems is among the fastest of authentication technologies, and some systems can operate reliably under challenging conditions. In emergency scenarios, the rapid operation of face recognition systems can help protect users' interests.
2. Safer and More Hygienic
Face recognition systems provide strong security and hygiene advantages compared with common alternatives such as fingerprint readers and access cards. From an information security perspective, face systems are supported by robust databases and continually improving algorithms. Face recognition can distinguish fine differences between individuals; even very similar-looking twins can be discriminated, and many systems now support accurate recognition when users wear masks.
From a hygiene perspective, contactless operation greatly reduces the chance of transmitting pathogens. This is a key shortcoming of fingerprint scanners and shared cards, and contactless face recognition can lower the risk of contact-transmitted infections.
3. Improved User Experience
Contactless recognition enhances user experience beyond hygiene concerns. Identification requires no deliberate action: users do not need to stop to find a card or free a hand to press a scanner. Typical recognition ranges are about 1-3 meters, and recognition speed can be under 0.2 seconds, making the process very fast. For multiuser attendance scenarios, many systems support simultaneous recognition of multiple people, which improves efficiency and saves time.
The points above summarize several key advantages of face recognition visitor systems. There are additional benefits beyond those described here, which become apparent with practical use.
