OPEnLOC wireless access permission system
OPEnLOC is designed for primary and secondary schools and public institutions to ease supervision of use of stationary wood and metalworking machines.
OPEnLOC consists of RFID receiver mounted on woodworking or metalworking machine and keychain transponder.
The machine is put into operation by placing the transponder near to the antenna of the receiver. Green indicator light shows that the machine is ready to use.
Access permission expires when transponder is placed again near to the antenna or the main current is turned off.
