Access control and biometric attendance systems: what to ask

Attendance registers get filled in late, and keys get copied. Biometric attendance and access control systems solve both — when they are chosen for how your workplace actually runs. The device is only half the purchase; the software, reports and support decide whether it keeps working for you.

Attendance only, or access control too?

• Attendance systems record who came in and when. They feed timesheets and payroll.
• Access control also locks and unlocks doors, so only authorised people can enter certain areas.

Many devices do both. Decide which doors need control — main entrance, server room, stores — and which only need attendance.

Fingerprint, face or card?

• Fingerprint is familiar and affordable, but can struggle with worn or dirty fingers — common in factories and workshops.
• Face recognition is contactless and fast, and handles large numbers of people well. Ask how it performs in low light and with helmets or masks.
• RFID cards or fobs are quick and suit visitors and contractors, but cards can be shared.

Many sites combine methods — face for staff, cards for visitors.

Standalone or networked?

• A standalone device stores records that are downloaded to a computer.
• A networked or cloud-connected device sends records automatically, lets you manage several locations, and shows attendance on your phone.

If you have more than one branch or want reports without visiting the device, networked systems save time.

Software and reports

Ask to see the software before buying.

1. Can it handle your shifts, weekly offs and overtime rules?
2. Can it export reports in the format your payroll or accountant uses?
3. Does it work with your existing payroll software?
4. Who can see and change records?

Privacy and data

Biometric data is personal information. Ask where the data is stored, who has access, and how employees' data is deleted when they leave. Tell your staff clearly what is collected and why.

Installation and support

• Ask whether installation, door locks, exit buttons and power backup are included.
• For access control, check what happens in a power cut or fire — doors must open safely.
• Ask about warranty, on-site service and how quickly an engineer can visit.

Mistakes to avoid

• Buying the device before seeing the software. The reports and shift rules are what your HR or accounts team will live with every month. Ask for a live demo using your own shift pattern.
• Ignoring the entrance conditions. A face terminal facing a bright glass door, or a fingerprint reader in a dusty workshop, will frustrate everyone. Tell the supplier exactly where each device will be mounted.
• No plan for power cuts. Doors with electric locks need a battery backup and a safe fail-open or manual override, especially on fire exits.
• Forgetting visitors and contractors. Decide how temporary people will enter — cards, a visitor register or a separate device — before installation, not after.
• No owner for the system. Name one person who adds new joiners, removes people who leave and checks reports weekly. Most attendance systems fail quietly because nobody maintains the user list.

What to include in your enquiry

• Number of employees and locations
• Attendance only, or access control (and how many doors)
• Preferred method: fingerprint, face, card, or a mix
• Standalone or networked, and your payroll software
• Installation, locks and power backup needs
• Your city and required date

Compare suppliers in safety, security and surveillance, or post your requirement with your staff count and doors.
