There is no single access method that is best for every site. The right choice depends on who needs access, how often they enter, how quickly people or vehicles must move through the entrance and what records the business needs to keep.
Facial recognition
Facial access can be convenient for regular staff because there is no card to carry. It can work well at controlled pedestrian entrances where authorised users are enrolled in advance.
Biometric access
Fingerprint and other biometric methods can provide a strong link between a user and an access event. The environment, hygiene requirements and the number of users should be considered when choosing the technology.
Cards, tags and PINs
Cards and tags remain practical for many businesses because credentials can be issued, replaced and cancelled easily. PINs can be useful as a secondary method or for lower-risk controlled areas.
QR visitor access
QR codes can simplify temporary visitor access when integrated with a suitable visitor-management process. Access can be limited by location, date or time depending on the platform.
ANPR for vehicles
Automatic number-plate recognition can identify vehicles at gates and parking entrances. It is often most effective when combined with barriers, intercoms, CCTV and a clear visitor or resident database.
Integration is where access control becomes powerful
Access events can be linked with gates, booms, turnstiles, intercoms, CCTV, time-and-attendance and other site systems. Designing the complete workflow is usually more important than choosing a reader in isolation.
