Abstract (en)
[origin: WO2013072578A1] 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.
