Problems solved by technology

[0018] Another disadvantage of this prior art device is that it is difficult to implement industrially
In fact, the realization of the switch or the insertion of the electronic components in the thickness of the contactless device increases the number of steps in the manufacturing process and thus increases the cost of the final product

Embodiment Construction

[0032] The radio frequency device according to the present invention is a contactless device for remote communication with a reader. The device according to the invention is advantageously applied to contactless cards or contactless tickets of the smart card standard format, or to passport covers known as "inlays". However, the apparatus described herein may be of another size without departing from the scope of the present invention. The device according to the invention comprises image 3 The support layer 311 is shown. The support layer 311 is made of paper, synthetic paper (Teslin type) or other material such as PET, PVC or polycarbonate. A loop is implemented on the first surface of the support layer 311 , including the antenna 312 , the chip 314 and a sensitive area 316 . Antennas, preferably planar, using conductive inks of the epoxy ink type filled with conductive particles such as silver or gold or using conductive polymers, by screen printing, flexographic printin...

Abstract

The invention relates to a portable contactless device consisting of at least two layers, a support layer (311) comprising, on the first face thereof, an antenna (312) formed from a planar winding of turns (310) that intersect each other via an electrically insulating bridge (309), a protective layer adhered to the first face of the support layer; the antenna comprises two cuts and consists of two strands and four ends (321, 322, 323 and 324) including two connection ends (321, 322) for connecting a chip (314). According to the principal feature, the antenna comprises two ends (323, 324) each extended by a pad (333, 334), said pads not being in contact with each other and being separated by a thin space (525) such that the antenna is open, the antenna being closed by the flow of a current between the two pads via the protective layer when a user applies a finger to the protective layer in the region of the pads, thus allowing communication between the chip and a reader connected to the portable contactless device.

Description

technical field [0001] The present invention relates to a radio frequency identification device with a device for interrupting operation, and in particular to a radio frequency communication device whose operation is controlled by the operator's gesture. Background technique [0002] Contactless radio frequency identification devices (RFID) are increasingly used to identify persons traveling in access controlled areas or passing from one area to another. As a result, security documents such as passports, ID cards, and other types of identification documents are being developed by leaps and bounds. A non-contact RFID device is a device composed of an antenna and a chip connected to a terminal of the antenna. The chip is not powered and receives its energy through the electromagnetic coupling between the reader antenna and the antenna of the RFID device, between which information is exchanged, in particular information stored in the chip, which involves, for example Identifi...
