Abstract
Abstract A card is coded with preselected partially completed circuits including selectively positioned insulators, a card reader is coded with second partially completed circuits and a plurality of manually operated contacts which are actuated in an array known only to the owner of the card, a mismatch completes the network through the card reader and the card and energizes a fuse device within the card to void the card. A coded circuit in the card corresponds to the stored amount of credit and an electrical network in the machine is operable by contacts corresponding to the amount of stored credit to complete a circuit to the fuse of the device to void the card when the credit is used up.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A verification system for an information card having a plurality of continuous and discontinuous concealed conductors arranged in the card according to a predetermined code pattern, a card-voiding element forming a part of one of said conductors, a card reader having a source of electrical power operable to energize said card-voiding element to void a card, and means in said card reader for comparing a memorized code with the code pattern of conductors in the card and for coupling said power source to said conductor having said card-voiding element when the codes do not match thereby voiding the card.
Claim 2
Dependent Claim
99 words
A verification system for an information card having a plurality of continuous and discontinuous concealed conductors arranged in the card according to a predetermined code pattern, a card-voiding element forming a part of one of said conductors, a card reader having a source of electrical power operable to energize said card-voiding element to void a card, and means in said card reader for comparing a memorized code with the code pattern of conductors in the card and for coupling said power source to said conductor having said card-voiding element when the codes do not match thereby voiding the card.
Claim 3
Dependent Claim
28 words
The verification system of claim 1 said comparing means including switch means having a plurality of contacts engageable with various ones of said continuous and discontinuous card conductors.
Claim 4
Dependent Claim
81 words
The verification system of claim 2 said continuous and discontinuous card conductors extending across said card, a plurality of second switch means spaced along said conductors and having contacts overlying the conductors, and a plurality of insulators interposed between the conductors and the contacts of said second switch means and arranged according to said coded pattern whereby said contacts will engage the insulators when actuated in accordance with the coded pattern so as not to cause energization of said card-voiding element.
Claim 5
Dependent Claim
19 words
The verification system of claim 3 further including means for storing a predetermined amount of credit in the card.
Claim 6
Dependent Claim
87 words
A verification system for an information card comprising a card having a plurality of conductors, a card reader including switch means having a plurality of spaced manually operated contacts overlying said conductors in the card and being operable upon engagement with said conductors to void the card, and a plurality of insulators interposed between the contacts and the card conductors and arranged according to a coded pattern whereby moving the contacts in accordance with the coded pattern into engagement with the insulators will not void the card.
Claim 7
Dependent Claim
87 words
A verification system for an information card comprising a card having a plurality of conductors, a card reader including switch means having a plurality of spaced manually operated contacts overlying said conductors in the card and being operable upon engagement with said conductors to void the card, and a plurality of insulators interposed between the contacts and the card conductors and arranged according to a coded pattern whereby moving the contacts in accordance with the coded pattern into engagement with the insulators will not void the card.
Claim 8
Dependent Claim
36 words
The verification system of claim 5 said card conductors being continuous and discontinuous and arranged according to said coded pattern, and second switch means having contacts operable upon engaging a continuous conductor to void the card.
Claim 9
Dependent Claim
32 words
The verification system of claim 6 including a card-voiding element in one of the conductors of said card and being operable to indicate that a mismatch has occurred and void the card.
Claim 10
Dependent Claim
19 words
The verification system of claim 6 further including means for storing a predetermined amount of credit in the card.
