Guides about time and attendance devices: fingerprint vs face, reports and payroll.

Time and attendance systems: the device is the easy part

Most attendance projects are judged on the wrong thing. The device that reads the finger or the face is rarely the problem; the trouble is almost always the rules, the reports and the link to payroll. Decide how you want to be paid out at the end, then choose the device that gets you there.

Reading methods and where each one fails

Fingerprint is the cheapest and most familiar, but it struggles with worn, dry, wet or dirty fingers — which is exactly the profile of manual workers, so it is the wrong sole choice for factories and construction sites. Face recognition is fast and contactless and handles those environments far better, but direct sun or strong backlight defeats it, so mounting position and shading matter. Palm and vein readers are the most tolerant of dirty hands but cost more. Cards are reliable and cheap, but nothing stops one employee clocking in for another — the classic buddy punching problem.

Capacity and speed matter more than you expect

A device rated for a few hundred templates will slow noticeably as it fills, and a queue at the gate at 8am is a real operational cost. For sites with a large simultaneous shift change, plan for more than one reading point rather than one faster device.

Connection: TCP/IP, not a USB stick

Devices that only export to a USB stick guarantee that someone must walk to each unit every month, and the data will eventually be collected late or not at all. Network-connected devices push records automatically, allow central management of employees and shifts, and let you see attendance in real time.

Shift rules are the actual project

Late allowance, early leave, overtime, night shifts crossing midnight, permission absences, holidays and weekly rest — these rules are where attendance systems succeed or fail. Before buying, take your two most awkward cases and ask the supplier to demonstrate them on the software. If the answer is "we will handle it manually", you have bought a clock, not a system.

Payroll integration

Ask specifically what the export looks like and whether your accounting package can read it directly. An attendance system whose output has to be retyped every month is a system that will be abandoned within a year.

Power and continuity

The device must keep its records through a power cut, and the clock must not drift. A backup battery and network time synchronisation are small details that prevent months of disputed timesheets.
