R3 Anti-Passback Bug Fixed!
R3 with anti-pass back feature turned on, after an anti-pass back verification is recorded, the device can not verify user anymore.
Please contact your local reseller or Fingertec Support team to retrieve latest firmware update.
The anti-pass back feature of the R3 device allows the admin to prevent users from tailgating behind other people. It does this by denying access to users that verify at the same terminal consecutively. For example, if the user enters a zone without verifying at the entrance terminal, they will not be able to leave that zone when they verify themselves at the exit terminal. This feature requires a slave device (usually R2c) in conjunction with R3 to function. Both will control the same door, one for the entrance and one for the exit.
