Electronic access control systems including pass-through credential communication devices and methods for modifying electronic access control systems to include pass-through credential communication devices

摘要

Electronic access control systems and methods address one or more weaknesses of conventional electronic access control systems. In some cases, an electronic access control system includes a secure communication channel for transmitting information to the access control system computer (ACC). In some cases, a method secures the communication channel between user access credentials (UACs) and the ACC.
