Abstract

Apparatus for providing a security feature including a magnetic identification (ID) card reader on computer I/O terminal 1 not having such built in. The apparatus is interconnected between terminal 1 and modem 2 to the communication system, and includes a magnetic-stripe card reader. The apparatus monitors data received by terminal 1, and upon detecting a special character sequence transmits to the host data read from the operator ID card.

Data Communications Terminal Security Badge Reader

Apparatus for providing a security feature including a magnetic identification (ID) card reader on computer I/O terminal 1 not having such built in. The apparatus is interconnected between terminal 1 and modem 2 to the communication system, and includes a magnetic-stripe card reader. The apparatus monitors data received by terminal 1, and upon detecting a special character sequence transmits to the host data read from the operator ID card.

Referring to the drawing, terminal 1 is adapted to communicate with a remote CPU through modem 2 over transmit line 5 and receive line 6 through RS 232 interface blocks 3 and 4. Security apparatus 20 monitors the data received on line 6 for a special character. Upon detecting that special character, apparatus 20 operates gates 8 and 9 to enable the security device 20 to communicate on transmit data line 5 through OR gate 7.

Special character monitoring is accomplished by routing, through universal asynchronous receiver transmitter 10, serial data on line 6, buffering it into a multibit (i.e., parallel) character for testing in special character decode 11. When the special character is detected, which would be, for example, two unprintable characters such as "prefix" and "restore", reader sequence logic 12 operates to close gates 8 and 9, and turn on ready lamp 13, signaling to the operator that he should insert his magnetic-stripe card into reader 15. Sequence logic 12 then cau...
