Affected Products & Versions

All device contains both card and fingerprint scanners(P2, W2, L2, A2, BS2, N2) current FW (30 August 2019)


When the device is set as Wiegand out in BioStar 2, it sends the wrong number through the Wiegand out when authenticating with fingerprint after card scanning from BioStar 2. 

The Wiegand device stores a scanned card value, and send out through the Wiegand out incorrectly when fingerprint authentication.

- This issue happens to device that is configured as a Wiegand output

- Due to the 2nd sequence, it does not occur when Suprema device is used as a Wiegand reader in third-party ACM (card scan command cannot be executed)

Reproduction process

1. 'Scan card' command for card registration (not authentication)

2. Fingerprint authentication (card authentication does not cause issues)
