Badge, mobile, or keypad: choosing access control for your building

Keys are hard to track. They are copied, lost, and rarely returned. Electronic access control replaces them with credentials you can issue, change, and cancel in seconds. The question is which kind fits your building and team.

The main options

• Badges or key fobs. A card or fob is held near a reader. They are familiar, simple, and work well for staff who come and go daily. A lost badge can be disabled immediately.
• Mobile credentials. A phone replaces the card. Nothing extra to carry or forget, and credentials can be issued remotely. They rely on people having a compatible phone.
• Keypad codes. Entry by PIN. Easy for small teams, but codes get shared and are hard to attribute to a person unless each user has their own.
• Biometrics. Fingerprint or face recognition. Strong identity assurance for sensitive areas, with privacy considerations to plan for.
• Combinations. Many buildings use badges at general doors and add a second factor, such as a PIN, for sensitive rooms.

What to compare

• Lost or stolen credentials. How fast can you disable one, and can you do it from anywhere?
• Staff turnover. Removing access when someone leaves should take minutes and be recorded.
• Schedules. Can doors unlock on a timetable, and can different people have different hours?
• Audit trail. Does the system record who entered where and when, and how long are records kept?
• Visitors and contractors. Can you issue temporary access that expires on its own?
• Power and network failure. Know what each door does if power or connectivity is lost, and make sure life-safety egress is never compromised.

Plan for people, not just doors

Decide who needs access to what, and write it down by role. Start with the doors that matter most: main entrances, server rooms, storage, and records. Add others over time.

Connect it to your cameras

When badge events and video are linked, you can click an event and see who was at the door. That makes investigating a problem much faster.

The best system is the one your team will actually use, administered by someone who is responsible for keeping it current.
