Attendance used to mean a register at the gate. Today, a single organisation may have office staff working hybrid, sales teams on the road, technicians at client sites and production workers on shifts. One attendance method rarely fits everyone. This article explains the main options, geofencing, facial recognition and biometric devices, and how to combine them sensibly.
Employees mark attendance on a mobile app, which checks their GPS location against a defined boundary around a site. If they are inside the boundary, the punch is accepted.
Good for: field sales, service technicians, staff at client locations, multi-site retail and construction.
Watch out for: GPS accuracy in dense buildings, employees without smartphones, and location spoofing apps. Set realistic radius sizes and decide whether out-of-fence punches are rejected or flagged for approval.
The employee takes a selfie in the app or stands in front of a kiosk camera, and the system matches it against an enrolled image. Often combined with geofencing to confirm both who and where.
Good for: preventing buddy punching, sites where touch-based devices are impractical, and remote locations where a kiosk tablet is cheaper than dedicated hardware.
Watch out for: lighting conditions, consent and data-protection obligations for biometric data, and a fallback when matching fails.
Fingerprint or face devices installed at entrances, typically in factories, warehouses and large offices.
Good for: high-volume shift changes where speed matters, and locations where many workers do not carry phones.
Watch out for: device downtime, data sync delays, and the work of mapping device IDs to employee records.
A practical policy assigns methods by role or location rather than by company:
| Group | Primary method | Backup |
|---|---|---|
| Factory and warehouse shifts | Biometric device | Supervisor-approved manual entry |
| Field sales and service | Geofence + selfie | Manager regularisation |
| Office and hybrid staff | Geofence at office, web punch when remote | Regularisation request |
| Contract staff at client sites | Geofence + facial recognition | Vendor supervisor approval |
The key is that all methods feed one attendance record per employee, so payroll does not need to merge separate sources.
The most common failure is not the device but the data flow. Check that:
Biometric and location data are sensitive. Good practice includes:
TankhaPay is a global HRMS and AI recruitment platform for every type of workforce, from corporate teams to on-roll, contract and shift-based staff across multiple states and entities. The TankhaPay HRMS attendance module supports geofenced mobile punches, facial recognition and integration with existing biometric devices, all feeding one attendance record that flows into payroll. For Indian operations, that data can drive TankhaPay's managed payroll service directly. TankhaPay is CMMI Level 5 and ISO certified and has served 2M+ employees.
The best attendance setup is the one employees can actually use and payroll can actually trust. Match the method to the work, centralise the rules, and treat privacy as a design requirement rather than an afterthought.
