Palm Vein Technology

Authentication based on blood vessels inside the palm

Palm vein recognition uses internal vascular patterns, not visible surface features. It shifts locker security from possession or memory-based access to user-based authentication.

Why Palm Vein

Contactless access
for locker-room privacy

Palm vein recognition uses internal vascular patterns. It reduces face-capture concerns and does not require direct fingerprint contact, making it suitable for shared lockers and storage cabinets.

01

Internal biometric

Uses vascular patterns inside the palm to reduce exposure and replication burden compared with surface features.

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, PINs or keys.

04

Locker-room fit

Reduces face-capture and fingerprint-contact burden in shared locker environments.

Comparison

Why palm vein recognition?

Conventional locker systems verify possession or knowledge. Palmlock verifies the actual user without contact.
