Choosing an attendance system usually starts with the hardware question: fingerprint machine, face recognition, card reader, or just an app on everyone's phone? Each has a place. The right choice depends on where your people work, how many punch at the same time, and what you're trying to prevent.
The quick comparison
| Method | Best for | Stops buddy punching? | Hardware |
|---|---|---|---|
| RFID card | Small offices on a budget | Partly — cards can be shared | Card reader + cards |
| Fingerprint | Most offices and shops | Yes | Fingerprint machine |
| Face recognition | Factories, shift changes, hygiene-sensitive sites | Yes | Face terminal |
| GPS geofence (mobile) | Branches, stores, remote sites | Yes — punch must be on site | None, uses phones |
| Field visit tracking | Sales and field staff | Yes — each visit has a location | None, uses phones |
RFID card readers
The cheapest way to get off a paper register. Employees tap a card at the reader. It's fast and simple, but the card proves who owns it, not who's holding it — a colleague can tap two cards. Good for small, trusted teams where speed and cost matter most.
Fingerprint machines
The default choice for most offices and shops. A fingerprint can't be lent to a friend, the machines are affordable, and people already know how to use them. Drawbacks: worn or dusty fingers (construction, manufacturing) can fail to read, and queues form if a hundred people arrive at 9:00.
Face recognition terminals
Contactless and quick, which makes them popular in factories, hospitals and anywhere a whole shift arrives together. They handle dirty or worn hands well. They cost more than fingerprint machines and need sensible placement — avoid strong backlight from a glass door behind the person.
GPS geofenced mobile attendance
No hardware at all: employees punch from their phone, and the app only accepts the punch if their GPS location is inside a circle drawn around the site. Ideal for small branches, retail stores and sites where installing a machine isn't worth it. It relies on employees having a smartphone with location on, and the radius has to suit the building.
Field visit tracking
For sales reps and service engineers who rarely start the day at an office, a fixed location doesn't make sense. Instead, each customer visit is logged with its map location, stops and outcome, and a manager approves it.
How to choose
- One office, under 30 people, tight budget: card reader or fingerprint.
- Office or shop with a single entrance: fingerprint.
- Factory or large shift changes: face recognition.
- Several small branches: geofenced mobile, with a machine at head office.
- Sales team on the road: field visit tracking.
Most growing businesses end up with a mix — and that's fine, as long as every method feeds the same attendance and payroll system.
The part that matters more than the hardware
A machine that stores punches locally just moves the spreadsheet problem: someone still downloads, cleans and reconciles the data every month. Whatever you choose, make sure punches go straight to a system that grades attendance, tracks leave and produces payroll — in real time, across all your sites.
Punchly supports all five methods side by side. Its fingerprint, face and card machines send every punch to the cloud the moment it happens, and the same dashboard covers geofenced mobile punching and field visits. Read more about the biometric attendance system.
