There is no single best method - there is the right method for your environment. For factory floors, the RFID card wins almost every time: fast, cheap and works with gloves and dirt. Biometric avoids forgotten cards but is more expensive and sensitive to the environment. Apps serve offices and mobile teams, not production.

RFID card

The employee brings a card close to the reader and is registered. It is instant, works with gloves, does not require a smartphone and the reader is cheap - bought once, belongs to the company. The only real disadvantage is the card can be forgotten or swiped by a colleague, but alerts and history discourage this.

Biometric (fingerprint or facial)

Uses the finger or face, so nobody can clock in for another person. In exchange: costs more per terminal, usually requires technical installation and struggles in environments with dust, humidity, oil or gloves - exactly where many factories work. GDPR also applies to biometric data.

Smartphone app

The employee clocks in on their own phone, with optional location tracking. Great for offices, sales teams and mobile workers. Not suited to factory floors: not everyone has a work smartphone, hands are occupied and phones are not on the production line.

Which to choose for your company

• Production, warehouse, workshop: RFID card.
• Clean environment with strong anti-fraud requirement: biometric.
• Office, sales teams, dispersed field work: app.
