DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE PRESENT INVENTION
The present invention relates to a method for effecting a transaction between at least one first plug-in data carrier incorporating a microcircuit, said carrier being of the type commonly referred to as an IC memory card or a microprocessor card, and at least one second data carrier, comprising at least the steps of setting up a relation between said carriers, reading said first data carrier, identifying the compatibility of said first data carrier with the second carrier and transferring data from one of said carriers to the other during a transaction between said first and second carriers via an interfacing circuit. More in particular, the invention relates to transactions in the field of intelligent cards, commonly called chip cards or smart cards, also referred to as microcircuit cards. The invention also relates to devices and accessories for carrying out the method according to the invention. It also relates to a plug-in data carrier incorporating a microcircuit enabling said method to be carried out.
Since the filing of the first patents in the nineteen seventies, the smart card has experienced considerable success and has come into widespread use, accompanied by a parallel growth in its technical capabilities and potential applications.
In this specification we shall use the term "microcircuit card" in preference to the terms "IC memory card", "smart card", or "microprocessor card" commonly employed to describe the same object. A microcircuit card can be defined, in the most general way, as a portable device for acquiring and storing information and/or data which is endowed with its own intelligence and includes provisions for identification and protection. The cards we are dealing with here are defined, at least as regards their physical format, by the ISO 7810 standard that specifies the physical structure of a type of card, generally referred to as a credit card. Another ISO standard, number 7811, defines, among other things, the position of the magnetic tracks currently employed for cards of a hybrid nature, particularly those intended for banking applications. Pursuant to the recommendations of the French Standardizing Association, AFNOR, ISO issued a "Draft International Standard"--DIS 7016 which not only defines the physical characteristics of the card such as those found in the ISO 7810 standard, but also defines the surface profile of the microcircuit contacts, along with numerous other parameters essentially relating to reliability and physical strength of the microcircuit. This provisional standard also determines the majority of the microcircuit's electrical parameters, notably the signals and protocols used in its dealings with the outside world, initialisation functions, transmission formats and standards, whereas a definitive choice between synchronous and asynchronous transmission has not yet been made.
While still on the matter of standards, three possible physical locations of the microcircuit on the carrier are currently accepted, a position at the top left hand corner which was initially chosen by the AFNOR, a position at the bottom left which should become the standard in France as from 1990 and a left hand middle position preferred by the ISO.
It is appropriate to make a distinction between passive cards which constitute the type of card in current use and which one could categorise as being a sort of portable information or data carrier, a read/write terminal being necessary in order to be able to read the data contained therein, and a new generation of cards which can be categorized as being active, incorporating their own power source, and their own display and keyboard; the extremely thin battery, rendered necessary in order to conform to ISO standards, currently preventing such cards becoming available. Although this invention is oriented towards the "passive" cards currently available, the means employed in the present invention are perfectly capable of handling both types of cards, whether they be active or passive.
