Abstract:
A radio frequency identification device support (2) featuring an antenna (12) screen-printed on a support (20) and a chip (10) connected to the connection terminals (17 and 19) of the antenna. According to a main characteristic of the invention, a thermoplastic layer (22) and a top layer of synthetic paper (24) are laminated on the antenna support (20) so that the antenna and the chip are trapped in the thermoplastic and the three layers (20, 22, and 24) cannot be separated and so that the device is resistant to water and humid environments.

Abstract:
A multi-step method for producing contactless tickets or cards, the tickets or cards including a chip (24) which is connected to an antenna (10) on a paper carrier. The method includes: printing the antennae in series on the paper carrier strip using a silkscreen ink; fixing a chip to each ticket by connecting bond pads of the chip to the antennas' bond pads (14, 16); and covering the paper strip, including the silkscreen-printed antenna and the corresponding chip, with an adhesive paper strip. After each step, the paper carrier strip is wound up before the next step is begun. Each of the silkscreen-printed antennae is coated with a protective layer (12) to prevent silkscreen ink from being transferred to the back of the paper carrier strip during the successive winding-up following each step.
Abstract:
Method of manufacturing a chip card having an antenna support, two card bodies and an electronic module or a chip linked to the antenna. This method has a first lamination step which includes fusing two thermoplastic sheets (32, 34 or 62, 64) on each side of antenna support (10 or 40) at a temperature sufficient for the thermoplastic sheet material to soften and to flow wholly so as to eliminate any differences in thickness from the support, and a second lamination step carried out after a period of time necessary for the thermoplastic sheets (32, 34 or 62, 64) to be solidified, the second step including fusing by hot pressing two plastic layers (36, 38 or 66, 68) making up the card bodies onto the plasticised and even faces of uniformly thick antenna support (30 or 60) plasticised by the thermoplastic sheets.
