Abstract

The invention relates to a contactless identification card or smart card, which is provided with at least two electronic chips. The first of these chips comprises the programming for the basic application of the card concerned. Furthermore, a switch is incorporated in this chip, with the aid of which the I/O contact can be connected on the card in accordance with ISO 7816 to the internal I/O line of this basic chip. By means of an instruction from the card reader, this switch can be changed over. With this mode of operation, the I/O line of the second chip can be connected to the I/O contact in accordance with ISO 7816 and the card reader can communicate with the application for which the programming in the second chip is provided.

Description

Chipkaart met meer dan één chip en gecombineerde I/O-lijn.Chip card with more than one chip and combined I / O line.

De uitvinding betreft een identificatiekaart of smart card, bijvoorbeeld met contacten volgens de internationale ISO-standaard ISO-7816, of in een contactloze uitvoering volgens de standaard ISO-10536. In de gangbare uitvoeringen bevat een dergelijke kaart een electronisch circuit in de vorm van een chip die via de contacten, of contactloos met een kaartlezer kan communiceren.The invention relates to an identification card or smart card, for example with contacts according to the international ISO standard ISO-7816, or in a contactless version according to the standard ISO-10536. In the conventional embodiments, such a card contains an electronic circuit in the form of a chip which can communicate with a card reader via the contacts or contactlessly.

Ook is het mogelijk een combinatie te maken van de contacten de contactloze funktionaliteit, zoals beschreven in de Nederlandse octrooiaanvrage nummer 9101608 van aanvraagster.It is also possible to make a combination of the contacts and the contactless functionality, as described in applicant's Dutch patent application number 9101608.

De toepassing van deze chipkaarten wordt bepaald door de programmering die in de electronische circuits is aangebracht en ligt hiermee per kaart vast.The application of these chip cards is determined by the programming that has been made in the electronic circuits and is therefore fixed per card.

Steeds vaker ontstaat in de markt echter de behoefte verschillende toepassingen, ook wel applicaties genoemd, te combineren of deze combinaties in een later stadium aan te brengen.However, there is an increasing need in the market to combine different applications, also known as applications, or to apply these combinations at a later stage.

De onderhavige uitvinding beoogt hiervoor een oplossing te bieden en zal aan de hand van een schematisch blokdiagram in het vervolg worden beschreven.The present invention aims to provide a solution to this and will be described below with reference to a schematic block diagram.

Figuur 1 toont een blokdiagram van de chipkaart volgens de uitvinding.Figure 1 shows a block diagram of the chip card according to the invention.

Chip (1) bevat een electronisch circuit, dat via contacten volgens ISO-7816 met een kaartlezer kan communiceren.Chip (1) contains an electronic circuit, which can communicate with a card reader via contacts according to ISO-7816.

Hierbij worden de voedingslijnen (4) (5), een kloksignaal (7) , een resetsignaal (6) en een input/output-signaal (1/0-signaal) (8) via de contacten met de chip verbonden.The power lines (4) (5), a clock signal (7), a reset signal (6) and an input / output signal (1/0 signal) (8) are connected to the chip via the contacts.

Naast deze contacten kan eventueel ook een contactloze verbinding via een spoel en eventueel capicitieve koppeling volgens ISO-10536 met de basischip (1) zijn aangebracht.In addition to these contacts, a contactless connection via a coil and possibly a capacitive coupling in accordance with ISO-10536 with the basic vessel (1) may also be provided.

Om deze kaart ook voor een andere applicatie te kunnen gebruiken is het mogelijk het geheugen van de chip (1) uit te breiden en de noodzakelijke programmering voor deze applicatie in de chip (1) aan te brengen.In order to be able to use this card for another application, it is possible to expand the memory of the chip (1) and to install the necessary programming for this application in the chip (1).

Bij de kaart volgens de uitvinding is echter de chip (1) voorzien van een electronische schakelaar (2), die via een daarvoor bestemde instructie door de kaartlezer kan worden bediend.In the card according to the invention, however, the chip (1) is provided with an electronic switch (2), which can be operated by the card reader via an appropriate instruction.

Tevens is in de kaart volgens de uitvinding voor een tweede applicatie een tweede chip (3) ingebouwd, die ook met de voedingslijnen (4) (5), het resetsignaal (6) en de klok (7) via de contacten zijn verbonden, doch waarvan de i/O-lijn verbonden is met schakelaar (2) van chip (1). Deze verbinding is zodanig tot stand gebracht, dat de schakelaar (2) het I/O-signaal (8) hetzij verbindt met de basis chip (1), hetzij met de via de schakelaar (2) verbonden I/O-lijn van de chip (3), bestemd voor de tweede applicatie.A second chip (3) is also built into the card according to the invention for a second application, which are also connected to the supply lines (4) (5), the reset signal (6) and the clock (7) via the contacts, but whose I / O line is connected to switch (2) of chip (1). This connection is made in such a way that the switch (2) connects the I / O signal (8) either to the base chip (1) or to the I / O line of the switch connected via the switch (2). chip (3), intended for the second application.

Zo kunnen op eenvoudige wijze en zonder dat de programmering van verschillende applicaties telkens in één chip gecombineerd moet worden toch meerdere applicaties in één kaart worden ondergebracht.In this way, multiple applications can be accommodated in one card in a simple manner and without the programming of different applications having to be combined in one chip.

Het is uiteraard ook mogelijk meerdere schakelaars (2) aan te brengen in de basischip (1) tesamen met meerdere chips voor andere applicaties.It is of course also possible to arrange several switches (2) in the basic ship (1) together with multiple chips for other applications.

De schakelaar (2) kan bijvoorbeeld worden uitgevoerd in de vorm van één of meerdere transistor(en).The switch (2) can, for example, take the form of one or more transistor (s).

Claims (1)

Een chipkaart of smart card voorzien van tenminste twee electronische chips met het kenmerk, dat één van deze chips de programmering voor de basis-applicatie van de betreffende kaart bevat, tesamen met een electronische schakelaar, bijvoorbeeld in de vorm van één of meerdere transistoren, met behulp waarvan het I/O-contact op de kaart volgens ISO-7816 kan worden verbonden met de interne I/O-lijn van voornoemde basischip en waarbij door middel van een instruktie vanuit de kaartlezer deze schakelaar kan worden omgeschakeld, waardoor de i/O-lijn van de tweede chip met het i/O-contact volgens ISO-7816 wordt verbonden en de kaartlezer dus kan communiceren met de applicatie waarvoor de programmering in de tweede chip aanwezig is. Een chipkaart of smart card volgens de voorgaande conclusie met het kenmerk, dat in de basischip meerdere schakelaars aanwezig zijn, verbonden met de I/O-lijnen van meerdere electronische chips, die met behulp van verschillende instructies vanuit de kaartlezer kunnen worden bediend, zodat meerdere electronische chips en dus meerdere applicaties in één kaart kunnen worden gecombineerd.A chip card or smart card provided with at least two electronic chips, characterized in that one of these chips contains the programming for the basic application of the relevant card, together with an electronic switch, for example in the form of one or more transistors, with by means of which the I / O contact on the card according to ISO-7816 can be connected to the internal I / O line of the aforementioned basic ship and whereby this switch can be switched by means of an instruction from the card reader, whereby the I / O line of the second chip is connected to the I / O contact according to ISO-7816 and thus the card reader can communicate with the application for which the programming is present in the second chip. A smart card or smart card according to the preceding claim, characterized in that the basic ship contains several switches connected to the I / O lines of several electronic chips, which can be operated from the card reader by means of different instructions, so that several electronic chips and thus multiple applications in one card can be combined.
