Abstract

Abstract A system for preventing improper use of credit cards having necessary data recorded thereon in card-actuated machines, wherein the system checks for a predetermined correspondence between the data read from a card inserted into the machine, and the data manually entered by the user of the card. If a correspondence does not exist, the stored number of times of absence of said correspondence with respect to the individual card is increased. When the stored number reaches a predetermined number, the card is invalidated.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 155 words
A system for preventing improper use of cards having necessary data recorded thereon in card-actuated machines, comprising: means for reading said data from each said card; means manually operated by the user of said card for inputting data into said system; means for checking whether a predetermined correspondence is present between said read data and said input data; means for storing the number of times of absence of said predetermined correspondence with respect to each said card, said storing means having the capability of indicating the total number of said absence of predetermined correspondence during the life of said card; means for increasing by one the number stored in said storing means when said checking means has decided that there is no correspondence between the read data and the input data; means for returning said card after said number has been stored; and means for invalidating said card when said number becomes a predetermined number.
Claim 2
Independent Claim 155 words
A system for preventing improper use of cards having necessary data recorded thereon in card-actuated machines, comprising: means for reading said data from each said card; means manually operated by the user of said card for inputting data into said system; means for checking whether a predetermined correspondence is present between said read data and said input data; means for storing the number of times of absence of said predetermined correspondence with respect to each said card, said storing means having the capability of indicating the total number of said absence of predetermined correspondence during the life of said card; means for increasing by one the number stored in said storing means when said checking means has decided that there is no correspondence between the read data and the input data; means for returning said card after said number has been stored; and means for invalidating said card when said number becomes a predetermined number.
Claim 3
Dependent Claim 16 words
The system of claim 1, wherein said storing means stores said number on each said card.
Claim 4
Dependent Claim 12 words
The system of claim 1, wherein said storing means is a computer.
Claim 5
Dependent Claim 23 words
The system of claim 1, further including means for decreasing said number stored in said storing means when said predetermined correspondence is present.
Claim 6
Dependent Claim 30 words
The system of claim 1, wherein said invalidating means is means for collecting each said card into said system so as not be returned to the user of said card.
Claim 7
Dependent Claim 20 words
The system of claim 1, wherein said invalidating means includes means for returning each invalidated card to the user thereof.
Claim 8
Dependent Claim 17 words
The system of claim 1, wherein said checking means compares said read data and said input data.
Claim 9
Dependent Claim 27 words
The system of claim 3, wherein said checking means compares said input data and the data derived from the computer on the basis of said card data.
Claim 10
Dependent Claim 27 words
The system of claim 3, wherein said checking means compares said card data and the data derived from said computer on the basis of said input data.
Claim 11
Independent Claim 112 words
A system for preventing improper use of cards in a card actuated machine comprising: card means for feeding data into said system, said card means having data recorded thereon; means for reading said recorded data; means manually operated for feeding data into said system; means for determining that said manually fed data is uniquely associated with said recorded data; means for incrementally recording an indication of the number of incorrect determinations of said unique association with respect to an individual card means, said recording of said incorrect determinations having the capability of indicating the number of said incorrect determinations during the life of said card means; and means for returning said card.
Claim 12
Independent Claim 112 words
A system for preventing improper use of cards in a card actuated machine comprising: card means for feeding data into said system, said card means having data recorded thereon; means for reading said recorded data; means manually operated for feeding data into said system; means for determining that said manually fed data is uniquely associated with said recorded data; means for incrementally recording an indication of the number of incorrect determinations of said unique association with respect to an individual card means, said recording of said incorrect determinations having the capability of indicating the number of said incorrect determinations during the life of said card means; and means for returning said card.
Claim 13
Dependent Claim 38 words
An apparatus in accordance with claim 10, wherein said determining means includes a means for comparing said manually fed data with a preselected number stored within said system, said preselected number being uniquely associated with said recorded data.
Claim 14
Dependent Claim 23 words
An apparatus in accordance with claim 11, wherein said card means is invalidated after a predetermined number of said incorrect determinations is recorded.
Claim 15
Dependent Claim 23 words
An apparatus in accordance with claim 12 including means to record said indication of the number of incorrect determinations on said card means.
Claim 16
Dependent Claim 36 words
An apparatus in accordance with claim 12 including means for storing said indication of the number of said incorrect determinations, said storing means having the capability of storing said indication during the life of said card.
