ABSTRACT:
TECHNICAL FIELD THE INVENTION
This invention relates generally to an improvement for the use of magnetic striping on devices such as credit cards and the like, and in particular, but not by way of any limitation to a methodology and improved magnetic stripe card which is capable of encoding additional information other than that originally presented on the card.
BACKGROUND OF THE INVENTION
In today's electronic commerce there has been a proliferation in the use of various types of credit, debit, identification and other types of authorization cards. For example, an average individual is likely to carry a driver's licence, several credit and/or debit cards, an identification card for access to a health club, an identification card to gain access to a place of employment and an access card to gain entry into a parking garage, among others. Furthermore, with advances in electronic commerce, smart cards are likely to replace paper and coin money resulting in an additional card for consumers to carry. Each of these cards typically incorporates a magnetic stripe or bar code to facilitate easy recognition of the card and to store various types of data. Although the use of these cards allow for easy and efficient electronic commerce, the number of such cards quickly becomes cumbersome and many individuals find carrying the large number of cards inconvenient.
Prior art magnetic stripe credit cards and the like have various limitations. For example, virtually all the prerecorded magnetic stripe cards that are currently in use are used for a single purpose. For example, a credit card or an identity card is generally used for just that purpose alone. In many instances, owners and users of these type of cards need to present several cards in order to maximize or complete a given transaction. Specifically, a discount card such as is used in certain supermarkets as well as the credit card to make the purchase must be both presented so as to obtain the discount.
Various solutions such as providing a sticker which can be placed on a credit card or the like have been suggested, however, these defeat the purpose of having an increased level of automation for check outs for example.
Accordingly, the inventor herein proposes a solution which is both cost efficient and time efficient and which allows the use of conventional types of magnetic stripe readers which are currently being used in most retail establishments. The invention herein also allows that a single swipe of the card through the magnetic strip reader can provide all the information in one pass. This can be accomplished by recording onto the conventional magnetic stripe of the credit card, the desired data from multiple cards and other sources which are necessary to complete a chosen transaction.
SUMMARY OF THE INVENTION
This invention uses a method and apparatus for providing onto the magnetic stripe of a card additional information and consolidating multiple information from multiple cards as well as other sources onto the magnetic stripe card. To do so a wallet consolidator such as is shown in co-pending U.S. patent application Ser. No. 09/087,193 filed May 29, 1998 (for which a Notice of Allowance has been issued) can be employed although other types of readers and writers can be used to generate this data and this invention should in no way be considered to be limited to the use of the specific wallet consolidator mentioned above. Specifically, a device such as the wallet consolidator can be used in which the magnetic stripe information from multiple credit cards can be read from what is generally the commonly used three ISO/8711 tracks that are present on the card. However, it should be noted that in many types of credit cards one or more of these tracks may have no data provided on the card. What then can be accomplished is the reading of multiple tracks from multiple cards storing this all in memory and then rewriting the information to either a blank card or to the existing card after erasing the information along with, if necessary, additional “foreign” data onto the card. In an other embodiment it may be possible to write the additional foreign data on an existing card without an erasure and re-writing of the data, however this is not the preferred mode of operation.
In one embodiment of this invention, the foreign data is placed at the end of any data which was originally on the track or on an empty track. It may also be placed at any other position that the reading software in a point of sale (POS) terminal would have or would find to be ideal, this could also be at the front of a track for example or embedded within the track. The data of each track is formatted with a start sentinel character followed by the data itself followed by a stop sentinel. Conventional magnetic swipe readers, which are presently used, look for the start or stop sentinel to indicate that a body of data follows. It should be noted however, that some readers will read the data irrespective of which way the card is swiped through the reader. The electronic circuitry in these type of readers know which way the swipe is being done by whether a start or stop sentinel is received first. This means that foreign data placed after the stop sentinel will not be recognized if it is not bracketed by standard start and stop sentinels.
The standard ISO-8711 standard (a copy of which is supplied hereto as an appendix) specifies that at least two machine control codes for each type of track specifically, the types of tracks can be for example 75 or 210 bpi. These control codes and be used to bracket the foreign data. It would then be possible to design the reader that will look for data bracketed by the special control codes and/or designed software that will look for the data bracketed by these special control codes after a standard stop sentinel. Foreign data such as a coupon information, a discount card number or the like may be written in any track that was originally unused or even if used after a stop sentinel is present, and if that foreign data is bracketed by these special control codes then the foreign data will not be read by standard magnetic swipe readers and therefore will be ignored. However, special readers in the software at the host computer for the transaction can look for these control codes and then confine the foreign data and organize it in a manner acceptable for multiple purposes in the individual cards. This makes it possible to have additional information placed on the magnetic stripe card which would not be read by conventional readers in the field but would be obtainable from specialized readers.
