Questions to review
before applying Palmlock

Direct-answer content for B2B customers, search engines and AI search systems.

How does Palmlock work with the manager app without internet connection?

Palmlock PLK-1000A is designed for offline standalone operation. The lock body operates without a server or internet connection, while the manager app uses NFC/BLE direct on-site communication for locker registration, user permission control and device status checks.

Can Palmlock be installed on existing locker doors?

Installation feasibility depends on locker door structure, door thickness, hinge direction and lock body compatibility. Left or right installation direction can be reviewed depending on the mechanical structure, and site photos help speed up the review process.

What problem does Palmlock solve in golf club locker rooms?

Golf club locker rooms often face forgotten PINs, lost cards, master-key calls and front desk workload. Palmlock allows members to authenticate with their palm, reducing reliance on cards, keys and PINs.

What are the advantages of replacing fitness locker cards with Palmlock?

In fitness centers, users often lose or misplace cards during workouts, changing or showering. Palmlock allows locker access without carrying a card, improving member convenience and reducing operational burden.

Can Palmlock be applied to hospital medicine cabinets?

Palmlock can be reviewed for medicine cabinets, sensitive item cabinets and controlled storage spaces that require user-based access control. User registration, deletion and device status checks can be managed through the app using direct on-site communication.

How is palm vein recognition different from fingerprint recognition?

Fingerprint recognition requires direct finger contact and can be affected by contamination, cuts or wet fingers. Palm vein recognition uses internal vein patterns in a contactless way, reducing touch burden in shared locker environments.

What are the advantages of palm vein recognition over face recognition?

Face recognition is contactless, but it can create privacy concerns because it involves face capture. Palmlock does not capture the face and uses internal palm vein patterns, combining contactless authentication with reduced privacy burden.

Can Palmlock manage users and permissions without a server?

Palmlock is designed for offline standalone operation. The manager app uses NFC/BLE direct on-site communication to register devices, add or delete users, manage permissions and check device status.

What is NFC/BLE direct on-site communication?

NFC/BLE direct on-site communication means that the administrator’s smartphone connects directly to the Palmlock device at the site to exchange setup and management commands. It enables on-site configuration without requiring a separate server or internet connection.

What should be checked during a PoC before deployment?

A PoC should review locker door structure, installation direction, lock body compatibility, user registration and authentication flow, manager app operation, battery replacement workflow and emergency opening procedures.
