01
Hidden biometric
Uses vascular patterns inside the palm to reduce exposure burden.
Palm Vein Technology
User authentication based on internal palm vein patterns
Palm vein recognition uses blood vessel patterns inside the palm, not visible surface features. It provides a different security, hygiene and operation profile from cards, PINs, fingerprints and face recognition.
Why Palm VeinContactless access
Contactless access
without face capture
Palm vein recognition uses internal vascular patterns. It avoids face capture and does not require direct fingerprint contact.
Hidden BiometricContactless AuthenticationNo Card · No PIN · No Key
02
Contactless
Users authenticate by placing their palm near the device.
03
User-based security
Access is based on the user’s own palm, not cards or PINs.
04
Lower operation burden
Reduces loss, sharing, reissue and master-key management burden.
Comparison
Why palm vein recognition?
Conventional locker systems manage keys. Palmlock authenticates the user.
| Item | PIN lock | RFID card | Fingerprint | Face recognition | Palmlock Palm Vein |
|---|---|---|---|---|---|
| Authentication method | Keypad input | Card tagging | Finger contact | Face recognition | Internal palm vein pattern |
| Loss / forget burden | High forgotten PIN | High lost card | Low | Low | Low no carried key |
| Sharing / proxy use risk | High shared PIN | High card handover | Low | Low | Low user’s own palm |
| Privacy burden | Low | Low | Medium fingerprint registration | High face capture | Low no face capture |
| Hygiene / contact | Contactless | Card contact/tagging | Contact required | Contactless | Contactless 10–30cm |
