How a kiosk punch works
The tablet runs the attendance app locked in kiosk mode, so it cannot be used for anything else. A worker walks up, taps their name or employee code, or scans their digital ID card QR, and looks at the camera. The app runs liveness detection and a face match against the enrolled descriptor, then records the punch with the kiosk's fixed location and the exact time. The whole cycle takes three to five seconds.
Because the device is fixed, the location is trusted by definition; there is no GPS spoofing risk. The identity risk moves to the face step, which is why a kiosk without face verification – just a list of names to tap – is barely better than a paper register.
Where kiosk mode fits, and where it does not
Kiosks suit factories, construction sites, warehouses, schools and hospitals: one or two gates, dozens to hundreds of people arriving in a window, many without a smartphone or with a phone they will not install company apps on. A ₹10,000–15,000 Android tablet on a wall mount with a power supply does the job of a fingerprint terminal, and it enrols a new contract worker in a minute from the same screen.
It does not suit dispersed teams: guards at 40 client sites, field sales, home-care nurses. There, per-employee mobile punching with GPS and selfie is the right tool. Many companies run both – a kiosk at the plant, mobile for supervisors and field staff – feeding a single record so the monthly muster roll is one report.
- Fix the tablet at the actual entry point, at face height, with a power supply and Wi-Fi or a SIM
- Enable offline mode so punches queue during a network outage
- Set the kiosk to a specific branch or site so punches are tagged correctly
- Position it away from direct sunlight; backlight is the most common cause of face failures
- Assign a gate supervisor to handle exceptions rather than letting a queue form
Kiosk versus a biometric machine
A fingerprint terminal needs a vendor SDK or a USB export to reach payroll, struggles with worn or dusty fingers on a construction site, and is a hygiene concern in food and pharma plants. A kiosk tablet runs the same app as everyone else's phone, so shift rules, grace period and late marks apply instantly and corrections flow through the same regularization workflow. See the attendance machine vs attendance app comparison for a full breakdown.
Shift A starts at 07:00 with a 10-minute grace. Two wall-mounted tablets at the main gate handle 180 workers between 06:40 and 07:10; each punch takes about four seconds, so both queues clear before grace ends. A helper who arrives at 07:14 is auto-marked late. The 12 contract workers who joined that morning are enrolled on the same tablet by the gate supervisor before their first punch, and appear on the contractor's muster roll the same day.
Attend Mitra includes a kiosk/tablet mode for shared devices, with face verification and liveness, offline queuing that syncs when the network returns, and per-site tagging. Kiosk punches sit in the same record as mobile, web and biometric-device punches, so one live monitor and one payroll export cover everyone.
