Your organization is considering replacing plastic key-fob badges with a mobile digital key solution that lets employees unlock office doors through an app on their smartphones. From a physical access-security perspective, which advantage of mobile digital keys most improves overall security compared with traditional key fobs?
The phone's GSM radio provides stronger encryption than proximity badge systems.
Credentials on the phone can be remotely disabled or updated in real time by security staff.
Digital keys continue to function even if the smartphone battery is depleted.
Employees no longer have to type a PIN at the door keypad to gain entry.
A credential stored on a phone can be issued, updated, or revoked centrally and almost instantly. If an employee loses a phone or leaves the company, the administrator can disable the digital key in the management console without having to re-key locks or wait for the user to return a badge. Traditional key fobs cannot be managed this quickly or remotely, so they present a larger window of exposure when lost or stolen. The other options either describe features not provided by mobile digital keys (continued operation with a dead battery), characteristics that do not improve security (GSM radio use), or benefits common to many systems (avoiding a PIN entry) and therefore do not represent the primary security advantage.
