The credential is only one part of an access control system, but it shapes cost, convenience and security.
Cards and fobs
Inexpensive and familiar. They can be lost or shared, and older low-security card technologies can be cloned, so choose modern encrypted formats.
Biometrics
Fingerprint, face or palm readers tie access to the person, which reduces sharing. They need clear privacy handling, enrolment processes and fallback for failures.
Mobile credentials
Phones become the credential, simplifying issue and revocation. Check device policy and battery expectations.

- Network and server security for the access control platform
Start with a door schedule that lists each door's risk, users and hours, then choose technology to fit.
