ZKTeco KR500 HID Compatible 125kHz Proximity ID Card Reader
KR500H
Due to its conveniently small mullion size, KR500H is the ideal card access solution for any metal doors with thin frames, parking gates, fences, turnstiles or any security device having a narrow mounting surface. For the highest level of security KR500H has a built-in Wiegand-Out port which can be connected to most any access control panel (including ZKAccess C3 and InBio door controllers).
