| Upfront hardware | A device per site, plus mounting and power near the door. | None. Employees use the phone they already carry. |
|---|
| Opening another location | Another device to buy, ship and install. | Create a workplace and choose its verification policy. |
|---|
| Adding a new starter | An enrolment session to capture the fingerprint. | An invitation they accept in the app. |
|---|
| What it verifies | A fingerprint — attendance tied to a body part. | Workplace location, workplace network and the employee’s registered device, chosen per site. A device, not a body part. |
|---|
| Buddy punching | Strongest available answer. | Registered-device checks narrow the gap without closing it entirely. |
|---|
| Typical failure | A dead unit or an unreadable fingertip. The day’s records are simply gone. | A flat battery or poor indoor reception. A manager reviews a correction, and the original event is kept beside it. |
|---|
| Time on the record | The terminal’s own clock. | Generated by the server, not read from the handset. |
|---|
| Best fit | One site, a stable team, or biometrics required by policy. | Several sites, a changing team, no hardware budget, or staff away from a fixed door. |
