Abstract

A cash replacement system using consumable transaction cards, each card comprising a body portion bearing multi-digit magnetically recorded validation and identification codes and a transaction portion divided into a plurality of transaction segments bearing the identification code and a denomination code, both magnetically recorded. A card reader senses the validation code and severs one transaction segment from the card for each transaction after checking the denomination and assuring presence of the required segment. Printed indicia on each card enable the user to determine the number and denomination of possible remaining transactions.

Claims

1. A consumable cash replacement transaction card comprising:

a body portion bearing a plural-bit machine readable indentification code characterizing the specific transaction card and distinguishing that card from all other cards in a multi-card series, and further bearing a multi-bit machine readable validation code common to all cards in the series; and

a transaction portion sub-divided into a plurality of individual transaction segments sequentially detachable from the card, each transaction segment bearing the plural-bit machine readable indentification code characteristic of the transaction card;

the card further bearing human readable indicia enabling the user to determine, at any given time, the number and denominations of transactions that may yet be completed by use of the card.

2. A consumable cash replacement transaction card according to claim 1 in which the machine readable codes are magnetically recorded in binary form.

3. A consumable cash replacement transaction card according to claim 2 in which each machine readable code is recorded as a cyclic pulse signal of constant cyclic displacement along a given track, with all excursions of one polarity present to provide a continuous clock output and with selected excursions of the opposite polarity omitted to provide a data output upon scanning of the track.

4. A consumable cash replacement transaction card according to claim 3 in which the waveform of the pulse signal is substantially sinusoidal.

5. A consumable cash replacement transaction card according to claim 1, claim 3, or claim 4 in which each transaction segment also bears a machine readable transaction denomination code.

6. A consumable cash replacement transaction card according to claim 5 in which the card comprises at least two transaction portions, the segments of the two transaction portions having different denominations

7. A consumable cash replacement transaction card according to claim 2, claim 3 or claim 4 in which the transaction card is of laminar construction, comprising at least one strip of magnetic film laminated between layers of magnetically inert material.

8. A consumable cash replacement transaction card according to claim 5 in which the card comprises at least two transaction portions, the segments of the two transaction portions having different denominations.

9. A cash replacement system comprising:

a multiplicity of consumable transaction cards, each card comprising a body portion bearing a plural-bit machine readable identification code distinguishing that card from all other cards in the system and a multi-bit machine readable validation code common to all of the cards, and a transaction portion sub-divided into a plurality of individual transaction segments sequentially severable from the card, each transaction segment bearing the plural-bit machine readable identification code, each card further bearing human readable indicia enabling the user to determing, at any given time, the number and denominations of transactions that may yet be completed by use of the card;

and a plurality of card readers, each including a first sensor for sensing the codes on the body portion of one of the cards, a validation data store having the validation code recorded therein, validity comparison means for comparing the validation code from the validation data store with a validation code output from the first sensor to determine the presence of a validity match, a second sensor for sending the presence of a transaction segment on the card, and transaction approval means, connected to the comparison means and the second sensor, responsive to the combination of a validity match and presence of a transaction segment, for approving a transaction;

completion of the transaction including severance of the transaction segment from the card.

10. A cash replacement system according to claim 9 in which each card further comprises segment severing means, actuated by the transaction approval means, for severing a transaction segment from the card.

11. A cash replacement system according to claim 9 or claim 10 in which each reader further includes an identification store having code data identifying invalid card identification codes recorded therein, and in which the validity comparison means also compares the recorded identification code data with an identification code output from the first sensor in determining the presence of a validity match.

12. A cash replacement system according to claim 9, claim 10, or claim 11 in which each transaction segment on each card also bears a machine readable denomination code, and in which each card reader includes denomination sensing means for sensing the denomination codes on the cards and settable denomination comparator means for comparing a denomination code from the denomination sensing means with a pre-set denomination code, and in which the transaction approval means approves a transaction only when a denomination code match is identified by the denomination comparator means.

13. A card reader for a cash replacement system utilizing consumable transaction cards, each card including a body portion bearing machine readable identification and validity codes and a pluraity o sequentially severable transaction segments each bearing the identification code, the card reader comprising:

a first sensor for sensing the codes on the body portion of one of the cards;

a validation data store having a validation code recorded therein;

validity comparison means for comparing the validation code from the validation data store with a validation code output from the first sensor to determine the presence of a validity match;

a second sensor for sensing the presence of a transaction segment on the card;

transaction approval means, connected to the validity comparison means and the second sensor, responsive to the combination of a validity match and the presence of a transaction segment, for approving a transaction;

and segment severing means, actuated by the transaction approval means, for severing a transaction segment from the card.
