Data security of Wiegand interface

Wiegand is a popular type of communication interface for door access systems, but it lacks
IT security protection. Data transmission is not secure because the interface is not
encrypted.
The communication cable and the area between the connected devices should be physically
protected from access by unauthorized people to avoid unauthorized data. The cable should
also be routed in the secured area.
The tamper detection feature of the reader should be used.
Data protection note: The card reader sends personal data (card number) over the unsecure
interface to the access management system. Check in advance if this is compliant with your
data protection regulations.

Reading distances

optimal reading distance.
