Abstract
Abstract A system is disclosed for use with credit cards which carry a magnetic recording medium and utilizes time or discrete use intervals to regulate the use of a card. A register for indicating a time, e.g., month and day, is associated with structure for providing electrical reference signal indicative of such time. A time is also sensed from the card in the form of electrical subject signals which are compared with the reference signals. The result of the comparison is indicated as a manifestation of the acceptability of the card, and the reference signals are recorded on the card as subject signals.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
197 words
A system for use in cooperation with an identification card bearing magnetic recording medium, comprising: a manually operable register, settable to manifest a predetermined time. switch means controlled by said register to provide binary reference signals indicative of the time registered by said register; means for sensing said recording medium, including at least one magnetic transducer head and means for moving said card in relation to said head to thereby provide electrical subject signals indicative of a time recorded on said recording medium; comparison means for determining the occurrence of said subject signals representing an earlier time than said reference signals to thereupon provide an approval signal; means for manifesting said approval signal; means for indicating a value of a current transaction as contemplated to be supported by said card; means for providing electrical signals representative of said current transaction value; means for sensing said recording medium to provide electrical signals representative of a value recorded on said card; means for accumulating said values represented by electrical signals to provide total signals; means for recording said total signals on said recording medium; and means for recording said electrical reference signals on said recording medium of said card.
Claim 2
Independent Claim
197 words
A system for use in cooperation with an identification card bearing magnetic recording medium, comprising: a manually operable register, settable to manifest a predetermined time. switch means controlled by said register to provide binary reference signals indicative of the time registered by said register; means for sensing said recording medium, including at least one magnetic transducer head and means for moving said card in relation to said head to thereby provide electrical subject signals indicative of a time recorded on said recording medium; comparison means for determining the occurrence of said subject signals representing an earlier time than said reference signals to thereupon provide an approval signal; means for manifesting said approval signal; means for indicating a value of a current transaction as contemplated to be supported by said card; means for providing electrical signals representative of said current transaction value; means for sensing said recording medium to provide electrical signals representative of a value recorded on said card; means for accumulating said values represented by electrical signals to provide total signals; means for recording said total signals on said recording medium; and means for recording said electrical reference signals on said recording medium of said card.
Claim 3
Dependent Claim
53 words
A system according to claim 1 further including means for providing value limit signals representing a limit for an identification card; means for testing said total signals representing accumulated value against said value limit signals; and means for actuating said means for manifesting said approval signal under control of said means for testing.
Claim 4
Dependent Claim
24 words
A system according to claim 1 wherein said manually operable register is settable to manifest time intervals of card use as said predetermined time.
Claim 5
Dependent Claim
43 words
A system according to claim 3 further including inhibit means for inhibiting the operation of said means for recording said electrical reference signals on said recording medium of said card; and means for actuating said inhibit means under control of said comparison means.
Claim 6
Dependent Claim
46 words
A system according to claim 3 further including bypass means for inhibiting operation of said means for accumulating; and means for controlling said bypass means under control of said comparison means upon occurrence of said subject signals representing an earlier time interval than said reference signals.
