摘要:
The invention concerns a manufacturing process for a contactless smart card (or ticket) which includes the following steps: a manufacturing process for an antenna consisting in screen-printing turns of an electrically conductive polymer ink onto a transfer paper sheet, and then subjecting said support to heat treatment in order to bake and polymerize said conductive ink, connection of a chip 14, provided with contacts, to the antenna 12, lamination consisting in making the transfer paper sheet integral with a layer of plastic material 16 which constitutes the support for the antenna, by hot press molding, in such a way that the screen-printed antenna and the chip are both embedded within the layer of plastic material, removal of the transfer paper sheet, and lamination of the card body onto the antenna support by welding at least one layer of plastic material (18, 20) by hot press molding on each side of the support.
摘要:
A smart card including an antenna (18) on a support made of paper type fibrous material (12), two card bodies on each side of the support each consisting of at least one layer of plastic material having a low flow temperature, and an electronic module (26) featuring a chip connected to the antenna, the assembly made up of the antenna support and the two card bodies being welded together by hot-lamination under pressure. The support made of fibrous material includes at least one opening (14, 16) such that the plastic layers (23, 25) of the card body come into near perfect contact during the lamination operation, the opening forming a weld between the card bodies thus reinforcing the connection of the module.
摘要:
A contactless portable device including a support layer and a protective layer, the support layer having, on its first side, an antenna made up of a flat winding of turns and a protective layer glued to the first side of the support layer, the antenna having two cuts, two wires and four ends including two connection ends for connecting a chip, and two ends each connected to a contact separated from one another by a narrow space so as to render the antenna open, such that the antenna is closed by flow of a current between the two contacts through the protective layer when a user places a finger on the protective layer where the contacts are located, and enabling communication between the chip and a reader associated with the contactless portable device.
摘要:
The invention concerns a method for manufacturing a radio frequency identification device (RFID), featuring a flat and flexible substrate made of polycarbonate equipped with an antenna (14) composed of conductive ink fully encased in the polycarbonate and a chip or integrated circuit module (29) connected to the antenna, the antenna formed by the winding of several turns features a turn overlap zone, an insulating strip of dielectric material separating the turns of the antenna in the overlap zone, the edges of the device being completely uniform so that no lines of demarcation between the various layers are visible, thereby preventing all attempt of delamination of the device over its thickness.

The invention concerns a method for manufacturing a radio frequency identification device (RFID) support (52) featuring an antenna (42) and a double-sided integrated circuit module (10) featuring internal contacts (13, 14) and external contacts (12) connected to a chip (15) encased in a module, the method including the following steps: printing the antenna (42) having contacts (43 and 44) on a support (40), creating a recess (41) between the contacts (43 and 44) of the antenna, pasting a film of glue (110) on the internal face of the module except on the internal contacts (13, 14), positioning the module on the support (40) on the antenna side and so that the internal contacts of the module are against the antenna contacts and the encapsulation (18) of the chip is in the recess, laminating together the support layer (40) and the module so as to connect the module to the antenna and to glue the module.
摘要:
Contactless label designed to ensure the traceability of an object featuring a microcircuit (16) and a Y-shaped dipole antenna connected to the microcircuit, which contains information necessary for tracing the object, which can be read with a reader through the exchange of ultra high frequency (UHF) electromagnetic waves. The antenna includes three main wires, a first main wire (10), a second main wire (12) forming a dipole with the first main wire and a third main wire (14) forming a second dipole with the first main wire. The angle between the first and second main wires is equal to the angle between the first and the third main wires and the angle between the second main wire and the third main wire is between 60° and 180°. Each of the main wires features a secondary wire (24, 26, or 28) at its end perpendicular to the main wire.

The invention concerns a device (10) featuring an optical reader (12) for printed codes capable of transforming the information of a code printed on an object such as a label into digital data, the object being equipped with a radiofrequency system featuring an antenna (27) and a chip (28) connected together. According to a main characteristic of the invention, the device features a radiofrequency dialog unit (15) designed to encode the chip (28) with digital data read from the printed code and to compare the digital data encoded in the chip with information from the printed code.
摘要:
A method for modification of data in a card transaction system having a memory card and a reader for reading the card. The card has a first memory (RAM) and a second memory (EEPROM) with data locations occupied by data recordings. Each transaction involves the modification of at least one of the data locations or the addition of a new recording. The method reads the address of a free location from a previous control register located in a first fixed location in the EEPROM memory, writes the new modified recording or addition in the free location, repeat the steps for each new recording to be modified or added, and writes in a second fixed location in the EEPROM memory a new control register containing the addresses of free locations within the EEPROM memory to use in the next transaction.
