Biometric and QR attendance for gyms
Connect eSSL, ZKTeco, Hikvision, Suprema and other biometric devices straight to Bison, so only members with a paid, active plan get in. Includes QR check-in too.

A biometric device at the door only helps if it knows who has paid. Bison Gym Manager connects your device directly to your members' memberships, so expired members are stopped at the door, not at the counter.
Devices that connect straight to Bison
No software on a front-desk PC is needed. The device talks to Bison over the internet.
| Device family | How it connects |
|---|---|
| eSSL, ZKTeco, Realtime, Identix | ADMS cloud push (the "Cloud Server" setting on the device) |
| Hikvision face and fingerprint terminals | ISAPI |
| Suprema BioStar 2 | BioStar 2 server |
| Matrix COSEC | COSEC server (beta) |
| Anything else | A webhook from the device or its software |
What happens at the door
- Entry follows the membership: when a plan expires or a member is blocked, the device refuses entry.
- Every punch becomes a check-in in Bison, so attendance and footfall reports are always complete.
- Devices stay in sync: when a member joins, renews, expires or is blocked, the change reaches the device automatically, and every night every member is re-checked on every device.
- Alerts tell staff when a device goes offline, or when someone entered without a valid plan.
QR check-in
Every member has a QR entry pass in the member app. Staff scan it with the staff app, or check members in at the front desk. A manager can override for exceptions.
Privacy by design
Fingerprints are enrolled on the device itself. Bison never stores fingerprint templates. From each punch it keeps only the member, the device and the time.
