In the latest firmware versions released since August 2018 ( starting with BioStation 2 and will be released so on), when scanning AoC(Access On Card) card, Card ID will be sent even if Bypass Mode is ON.
Here the Card ID on Access on Card would be same as User ID. In this article the reference to Card ID = User ID
Here in this example, BioStation A2 (Output Device) is connected to FaceStation 2(Input Device).
Please refer to the link below on how to issue an Access on Card (AoC), a type of a smart card.
1) Set Bypass Mode ON on Output Device (Device -> Advanced -> Wiegand section)
*Please make sure that Pulse Width and Pulse Interval are matched between two Wiegand Input & Output devices based on the device specification.
Please refer to the FAQ below.

2) Set CSN card format (Device -> Authentication -> CSN Card Format section)
*It is important to set CSN card Format as Wiegand for Wiegand Output device. Also ensure that Wiegand Format is unified across all of the settings(Here in this example, it's 26 bit).
