Patent Images
1. An electronic identification system employing a data bearing identification card comprising:
- means for receiving said card;
means for sensing the data on said card;
keyboard means for accepting a manually entered identification code;
data scrambling means connected to said sensing means for modifying the data sensed from said card in order to affect coincidence between said sensed data and said identification code;
means for comparing said manually entered identification code with the modified data sensed from said card; and
means operable by said comparing means when said modified data coincides with said identification code to cause said receiving means to release said received card.

- 13. A plant security system for selectively controlling a barrier in a passageway in response to a code entered into a manual keyboard and a code automatically sensed from an identification card comprising, barrier means controlling the open and closed condition of said passageway, actuator means for operating said barrier means, means for receiving said card, means for sensing the code from said card, scrambling means for modifying the data sensed from said card in order to effect coincidence between said sensed data and the code entered into said keyboard, comparing means for comparing data from said keyboard with the modified data from said scrambled means, and means operable by said comparing means to energize said actuator means and control said barrier to maintain said passage in an open condition.
- 19. An electronic identification system for controlling the admittance of entrants through a passageway comprising, barrier means for controlling the open and closed condition of said passageway, means for selectively controlling said barrier means to permit an entrant to proceed through said passageway, said controlling means comprising means for receiving an encoded identification card carried by said entrant, keyboard means operable by said entrant to place a code in said controlling means, said card having thereon two distinct groups of encoded information, and comparing means for simultaneously reading both groups of information from said card and comparing same with the code placed in said controlling means from said keyboard means, said controlling means being responsive to said comprising means to open said barrier means to permit said entrant to proceed through said passageway when at least one group of information on said card compares with the information in said controlling means.
- 23. An electronic identification system for controlling the admittance of entrants through a passageway comprising, barrier means for controlling the open and closed condition of said passageway, means for selectively controlling said barrier means to permit an entrant to proceed through said passageway, and controlling means comprising means for receiving an encoded identification card carried by said entrant, keyboard means operable by said entrant to place a code in said controlling means, and comparing means for reading the information encoded in said card and comparing same with the code placed in said controlling means from said keyboard means, said controlling means being responsive to said comparing means to open said barrier means to permit said entrant to proceed through said passageway when the information encoded in said card is identical to the information placed in said keyboard means.
