Hybrid contact/contactless integrated circuit card, the strength of the electronic module of which is reinforced

Abstract

The invention relates to a hybrid contact / contactless smart card (1), including a card body consisting of a plurality of layers, from among which a so-called support layer (40) supports a printed antenna (41) consisting of at least one coil, and supports an integrated circuit module (10) connected to the antenna via two inner and outer connection contacts (43, 44) arranged in alignment with the inner and outer ends (45, 46) of the antenna coils, respectively, the module being located on the card in a portion delimited by a first side (6) of the card, a second side (8) of the card perpendicular to the first side, a first line (3) parallel to the first side (6) of the card, and a second line (4) parallel to the second side of the card.; According to the main characteristic of the invention, the inner end (45) of the antenna coils, which is connected to the inner contact (43), is located entirely in said portion, such that when the card is bent and / or twisted, the connection between the module and the antenna is not broken.

Description

technical field [0001] The present invention relates to a non-contact radio frequency identification device (RFID), and more particularly to a contact-non-contact hybrid integrated circuit card with a ruggedized integrated circuit module and a manufacturing method thereof. Background technique [0002] A non-contact type RFID device is a device composed of an antenna and an integrated circuit connected to an antenna terminal. The integrated circuit is usually not powered and receives its energy through electromagnetic coupling between the reader antenna and the antenna of the RFID device, information is exchanged between the RFID device and the reader, and more specifically, is stored in the integrated circuit The information in is related to the identification of the owner of the item, with the RFID device on the item and the permission to enter the controlled access area. [0003] A contact-contactless hybrid integrated circuit card is a contactless RFID device with the d...

The disadvantage presented by this type of card is the fragile strength of the provided electronic modules on the card

In fact, the antenna support of fibrous material (such as paper) has the advantage of retaining the "memory" of the bending of the card, but between the glue seam (the glue seam holds the module on the card and is therefore perpendicular to the thinner part of the card body). After the underlying paper delamination produces multiple wrinkles, the card lacks favorable internal cohesion, thus causing disconnection of the electronic module and antenna
