The KeyMaster AC-1100 is a slimline proximity card reader/writer for a range of contactless
identification and transaction applications, including access control, time & attendance
reporting, membership cards, electronic keys, parking systems and prepaid card systems.
The AC-1100 employs very large scale integration (VLSI) surface-mount components, and
utilizes the I/O capability of the system controllers to deliver a compact, flexible proximity
solution. A single tri-color LED and an internal piezo buzzer indicate status and error
information.
