Abstract
Abstract A card reader system in which a combination of data indicia, and clocking and timing indicia are present simultaneously on a coded card, for example, an identity card or boarding pass, which is insertable into the card reader. As a card is inserted, clock pulses are generated in accordance with the clock markings on the card which clock data is sensed from the coding, and is transferred into a shift register at a variable clock rate and from the shift register into a central computer at a different clock rate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
236 words
A reader system comprising: a manually positionable element, said element having a first series of markings and a second series of markings; and means for receiving said element, said receiving means being adapted to permit manual insertion therein of said element, said receiving means comprising: first reading means positioned for reading said first series of markings; second reading means positioned for reading said second series of markings; means coupled to said first reading means for storing data represented by said first series of markings; and means coupled to said second reading means for clocking said data into said storage means; said second reading means including means for providing a pulse delayed from a reading of said second series of markings, said storing means comprising means coupled to said delay means and to said first reading means for forming a pulse which is terminated by said delayed pulse and which corresponds to a mark of said first series of markings, said storage means further comprising a shift register and means for switching selectively pulses from said pulse forming means and from an output of said shift register to an input of said shift register to permit recirculation of pulses stored within said shift register, and said storing means including means for selectively switching pulses from said delay means and from an external source of clock pulses to said shift register for clocking data through said shift register.
Claim 2
Dependent Claim
236 words
A reader system comprising: a manually positionable element, said element having a first series of markings and a second series of markings; and means for receiving said element, said receiving means being adapted to permit manual insertion therein of said element, said receiving means comprising: first reading means positioned for reading said first series of markings; second reading means positioned for reading said second series of markings; means coupled to said first reading means for storing data represented by said first series of markings; and means coupled to said second reading means for clocking said data into said storage means; said second reading means including means for providing a pulse delayed from a reading of said second series of markings, said storing means comprising means coupled to said delay means and to said first reading means for forming a pulse which is terminated by said delayed pulse and which corresponds to a mark of said first series of markings, said storage means further comprising a shift register and means for switching selectively pulses from said pulse forming means and from an output of said shift register to an input of said shift register to permit recirculation of pulses stored within said shift register, and said storing means including means for selectively switching pulses from said delay means and from an external source of clock pulses to said shift register for clocking data through said shift register.
Claim 3
Dependent Claim
46 words
The system according to claim 1 further comprising means coupled to said storage means for extracting said stored data; and means coupled to said extracting means for displaying said data, said clocking means providing a clock pulse for each marking of said second series of markings.
Claim 4
Dependent Claim
39 words
A system according to claim 1 wherein said receiving means comprises: a source of radiant energy; and means for guiding said radiant energy towards said element for illuminating said element when said element is inserted in said receiving means.
Claim 5
Dependent Claim
32 words
A system according to claim 3 wherein illuminating energy is reflected from said element, and wherein said first and said second reading means comprise means positioned for detecting said reflected radiant energy.
Claim 6
Dependent Claim
34 words
A system according to claim 4 wherein said guiding means has a recess for said insertion of said element, and wherein said guiding means supports said source of radiant energy and said detecting means.
