Which biometric time and attendance system is better?
This is debatable, but for the following reasons, fingerprint technology is more practical.
- With face scanners, you have to be more precise, where, and how far, you need to stand in front of the unit. This means it takes longer to scan the face, and if you have a queue waiting to clock in, it may cause a delay. Whilst, fingerprint is faster. Touch and Go.
- Face scanners may not work in direct sunlight especially if it is one of low quality, whilst fingerprint readers operate better in these conditions.
- Whilst, fingerprints remain the same, facial features can change with time, makeup or other reasons. For example if you grow or shave your beard or start wearing glasses your face will not be recognized and will be rejected by the scanner because it doesn’t match the biometric template stored in the unit.
- With fingerprint devices, you can actually enrol more than one finger. This means if you cut one finger you can always use another one.
- Fingerprints can be enrolled using a USB enroller from a central point, for example the HR office. This makes the process of enrolling a lot more convenient and simpler, whilst with face scanners you have to be in front of the device to carry out this function.
