Biometric vs mobile attendance depends on where people work, how they reach work and what the attendance record has to prove. Many organisations use both.
Check before you rely on thisCheck your current obligations under the Digital Personal Data Protection Act 2023 and its rules before collecting biometric or location data.
01
A biometric device at a fixed entry point records that a particular person was physically at that device at a given time. It is strong evidence of presence at one location.
Mobile attendance records a punch from the employee's phone, usually with location and sometimes a photo. It suits people who do not start at one fixed gate: field staff, sales teams, people working across sites or from home.

| Factor | Biometric device | Mobile app |
|---|---|---|
| Best for | One or a few fixed sites | Field, multi-site and remote work |
| Identity assurance | High at the device | Depends on photo and location checks |
| Location proof | The device's location | Phone location at punch time |
| Hardware | Devices to buy, mount and maintain | Employee phones |
| Failure points | Device down, worn fingerprints, queues at shift change | No phone, no data signal, location switched off |
| Data flow | Device logs synced into the attendance system | Usually direct into the system |
Watch for itBoth methods produce punches, not attendance. Hours, lateness and overtime still come from applying shift and policy rules to the punches.

Fingerprints, face images and location are personal data. Tell employees what is collected, why, who can see it and how long it is kept, and collect no more than the attendance purpose needs. Check your obligations under the Digital Personal Data Protection Act and its rules as they apply to you.
Location can be spoofed on some phones, and someone else can carry a phone. Photo capture, location limits and manager review reduce this. Where proof of identity at a gate matters most, a device is stronger.
The law asks for accurate attendance and wage records, not a particular capture method. Whatever you use must produce reliable registers.
It should go through a regularisation request with approval, so the correction is recorded rather than overwritten.
