Definitions
- the invention relates to a portable data carrier with a substrate, in particular a chip card, smart card, smart label or smart tag.
- Various portable data carriers are known from the prior art, which in general are commonly referred to as smart cards, smart cards, smart labels or smart tags. A distinction is made here, for example, between memory cards, microprocessor cards and contactless cards.
- the memory cards generally have integrated security logic in order to protect the stored data from manipulation. For example, they are used as prepaid cards.
- Microprocessor cards are characterized by a microprocessor integrated into the card that can be freely programmed.
- the possibility of storing secret keys and executing cryptographic algorithms by the microprocessor has made it possible to implement offline payment systems with a relatively high level of security.
- Another important area of application for microprocessor cards is mobile telephony, where they are used as so-called subscriber identity modules (SMs).
- SMSs subscriber identity modules
- Both memory cards and microprocessor cards can be made contactless. Such contactless cards are particularly suitable for applications in the area of access control and electronic ticketing in local public transport.
- optical memory cards with an optical memory on the chip card for applications for which the space available on the chip of the card is not sufficient.
- chip card systems that allow interactive use have also been known from the prior art.
- DE 199 14 587 shows a chip card with keypads integrated in the card body for the input of data by a user.
- a common disadvantage of such previously known chip cards is that there is no correspondingly reliable protection against the module being separated from the crimp card body and the module being inserted into another chip card body. This basically allows manipulation, for example by removing the module from a card and misusing it in conjunction with a counterfeit card body. Corresponding manipulations are conceivable, for example, in chip card applications for access control.
- the object of the invention is therefore to create a portable data carrier which is improved compared to the prior art.
- the integrated circuit of a chip card or at least part of it forms an integral part of the chip card, which cannot be separated from the chip card without being destroyed.
- the card body is used as a substrate on which a polymer-based integrated circuit is applied. A separation of the integrated circuit from the chip card is therefore fundamentally excluded.
- such a polymer-based integrated circuit is applied directly to the substrate formed by the card body, so that the polymer-based integrated circuit forms an integral part of the portable data carrier. det, which can not be separated.
- a conventional plastic such as, for example, acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC) or polyethylene terephthalate (PET), can be used as the card body.
- ABS acrylonitrile-butadiene-styrene
- PC polycarbonate
- PVC polyvinyl chloride
- PET polyethylene terephthalate
- the polymer-based integrated circuit can be applied directly to this plastic surface of the card body; alternatively, a further layer is first applied to the plastic surface in order to facilitate the application of the polymer-based integrated circuit to the substrate.
- the polymer-based integrated circuit is applied to the substrate by means of a printing process.
- Inkjet printing processes, stencil or screen printing, letterpress printing, gravure printing and planographic printing are particularly suitable as printing processes.
- the desired electrically conductive, insulating or semiconducting polymer-based materials are used for printing on the polymer-based integrated circuit.
- a multi-layer printing process By using a multi-layer printing process, several circuit levels of the polymer-based integrated circuit can be printed on top of one another.
- the portable data carrier contains a conventional IC chip in addition to the polymer-based integrated circuit.
- a conventional silicon or germanium-based IC chip is integrated into a module which is inserted into a cavity in the card body.
- the remaining substrate surface can be used for the application or printing of the polymer-based integrated circuit, which is electrically coupled to the IC chip.
- card functions can be shifted from the IC chip to the polymer-based integrated circuit.
- additional memory space and / or additional logic functions can be made available by the polymer-based integrated circuit.
- the polymer-based integrated circuit contains a security feature for querying the IC chip.
- this security feature is a code word stored in the polymer-based integrated circuit, which is queried by the IC chip.
- Cryptographic techniques can be used here.
- the chip card has a function module, such as a sensor, actuator or an input or display device.
- a function module such as a sensor, actuator or an input or display device.
- a furcation module is preferably also applied or printed onto the substrate as a polymer-based integrated circuit. So-called organic light emitting diodes (OLEDs), for example, can be used to implement a display.
- OLEDs organic light emitting diodes
- the polymer-based integrated circuit is designed to control such a functional module.
- the polymer-based integrated circuit is electrically connected to the functional module, for example by means of a printed conductor printed on the substrate.
- a portable data carrier with different radio Produce tional components which is also referred to as a chip card system or as a "Super Smart Card”.
- a further layer is applied to the polymer-based integrated circuit in order to mechanically protect the polymer-based integrated circuit. Motifs or markings can be placed on or in this layer in order to use the chip card, for example, as an advertising medium. Preferred embodiments of the invention are explained in more detail below with reference to the drawings. Show it:
- FIG. 1 shows a section through an embodiment of a chip card according to the invention
- FIG. 2 shows a block diagram of a further embodiment of a chip card according to the invention
- FIG. 3 shows a block diagram of a further embodiment of a chip card according to the invention with a display.
- FIG. 1 shows a section through a chip card 1.
- the chip card 1 has a card body 2, which consists, for example, of a conventional plastic.
- the card body 2 serves as a substrate for applying a polymer-based integrated circuit 3.
- the polymer-based circuit has a plurality of circuit levels 4, 5 and 6, which are printed on the card body 2 in succession, for example in a multi-layer printing process.
- the circuits of circuit levels 4, 5 and 6 can be contacted with one another in the vertical direction by so-called vias in order to create a coherent polymer-based integrated circuit.
- a further layer is preferably applied to the surface 7 of the polymer-based integrated circuit 3.
- this can be a further plastic layer, which consists of the same or a different plastic as the card body 2.
- This layer can also serve as a carrier for prints or labels. It is particularly advantageous with the chip card 1 that the polymer-based integrated circuit 3 forms an integral part of the chip card that cannot be separated from the cardiac body 2 without being destroyed. Because of this, manipulations are practically excluded.
- FIG. 2 shows a further embodiment of a chip card 8 according to the invention with a card body 9.
- the card body 9 has a cavity in which a module 10 is located.
- the chip card 8 preferably has a standard-compliant format, for example in accordance with the ISO 7810 standard, with an arrangement of the module 10 conforming to the norm.
- the module 10 contains a conventional IC chip which can be contacted by a chip card reader via the module 10.
- a polymer-based integrated circuit 11 is located on or in the card body 9 and is applied to an area of the card body 9.
- the polymer-based integrated circuit 11 is electrically connected to the IC chip in the module 10 via lines 12, which are used for voltage supply and signal transmission.
- the lines 12 are printed on the card body 9 with a conductive printing ink.
- the chip card 8 To operate the chip card 8, it is inserted into a chip card reader which contacts the module 10 in a manner known per se and supplies it with voltage. The polymer-based integrated circuit 11 is then also supplied with voltage via the lines 12.
- the IC chip of the module 10 reads the content of the memory 13 of the polymer-based integrated circuit 11, which contains a cryptographic key. This cryptographic key is evaluated by the IC chip in order to check whether the IC chip of the module 10 belongs to the polymer-based integrated circuit 11.
- the chip card 8 can only be used if this is the case; otherwise, the IC chip in the module 10 blocks the function of the chip card 8. This prevents the module 10 from being removed from the chip card 8 in order to replace it with another one.
- a security feature can be stored in the IC chip of the module 10, which is evaluated by the polymer-based integrated circuit 11.
- both the laser direct writing method mentioned and the ink jet printing technology or another printing method can be used.
