Fingerprint Access Control Keypad: Why It Beats Pure PIN

Fingerprint Access Control Keypad: Why It Beats Pure PIN

Passwords get shared, forgotten and written down on sticky notes. A fingerprint access control keypad removes the weakest link in your door security. The SK-37STT TTLock fingerprint keypad combines biometric fingerprint with card and PIN access.

Fingerprint access control keypad

Fingerprint vs PIN Only

  • No shared passwords – each user has a unique fingerprint, no PIN to share or forget.
  • Audit trail – know exactly who entered, not just “someone with the code”.
  • Faster unlock – a tap of the finger beats typing a 6-digit code, especially for hands-full users.
  • Scalable – add or remove fingerprints instantly without reprogramming a master PIN.

10000 Cards + 100 Fingerprints

The SK-37STT stores up to 10000 cards and 100 fingerprints. That makes it suitable for office buildings, factories and multi-tenant properties where dozens of users need daily access but not everyone uses a fingerprint.

Features of fingerprint access keypad

IP66 Outdoor and Night Vision

The zinc alloy housing is IP66 rated — dust-tight and protected against powerful water jets. The illuminated keypad works in pitch-black corridors. Built-in night vision means you can verify who is at the door after dark.
