Problems solved by technology

Commonly used booster antennas extend in most cases over the entire area of ​​the smart card, possibly also over a partial area, which is provided, for example, for embossing text in the smart card (embossing area, for example in ISO / IEC 7811-1 specification) or for chip-cavities, so such chip cards basically do not comply with ISO / IEC
In addition, in chip cards until now no optimization of the booster antenna has been achieved with regard to the electronic parameters of the booster antenna, so that such a chip card cannot, for example, be certified according to the EMVCo standard, the global standard for credit and bank cards based on chip card technology.

Abstract

In various embodiments, a booster antenna structure for a chip card is provided, wherein the booster antenna structure may include a booster antenna; and an additional electrically conductive structure connected to the booster antenna.

Description

technical field [0001] Various exemplary embodiments relate to a booster antenna structure for a smart card. Background technique [0002] Conventional chip cards, which are widely used, for example, for electronic payment transactions, in which the communication between the chip located on the chip card and the reading device takes place on the basis of contact, that is to say by means of a contact towards the outside of the chip card The exposed chip card contacts enable communication. Furthermore, the chip card has to be continuously detached and inserted into a corresponding reading device during use, which may be perceived by the user as a nuisance. An interesting development solves this problem by providing a so-called Dual Interface chip card in which, in addition to the usual contact-based interface, the chip can also be Contact interface communication. The contactless interface on the smart card has a smart card antenna which is contained in the smart card and co...
