Security device for controlling access to a computer or a network terminal

摘要

The access control has the access code recorded on a portable support which is placed near a detector. The detector reads the access code from the portable support and is connected to the computer or to the network to transmit the code read from the support. The support is a disc that is inserted in the computer or a smart card (8) that is placed on a surface so the mouse can be run over its surface. The mouse (5) then has an inductive detector built into it to read the data and to deliver the access code over the mouse connecting cable to the computer. Alternatively the reader can be incorporated in the keyboard or built into the keyboard or terminal.
