The invention relates to a male device comprising an elongate portion and an antenna. The elongate portion extends in one direction between a first end and a second end, and is intended for receiving at least one female device by threading from the first end. The near-field communication antenna is placed inside the elongate portion and comprises at least one conductive turn comprising two connection terminals at the second end, the two connection terminals being intended for being connected to a reading circuit, the conductive turn being positioned so as to produce at least one magnetic field generating a flux passing through the elongate portion perpendicularly to the direction when the antenna is traversed by a current produced by the reading circuit.

Male device, electronic tag and near-field communication system

The invention concerns a method for detecting the handling of products on a display stand by a person, the products being provided with electronic tags, each person being associated with a communicating object, the display stand comprising a near-field communication device and at least two receivers. The method comprises the repetition of: a product inventory step during which the display stand sends and receives messages communicated by near-field communication in order to identify and locate the products; a step of comparing inventories in order to determine, between two successive inventories, a product removed from or added to the display stand and the position thereof; a step of locating a person by triangulation using the radio-frequency receivers receiving a signal from the communicating object; an association step during which a person is associated with a product when they are close.

Method for detecting the handling of products on a display stand, display stand and automated shop

The invention relates to a near-field communication surface intended to communicate with at least one electronic tag. The surface comprises a plurality of antennas, each antenna having a position along an axis, a circuit for reading electronic tags that is connected to said antennas in order to supply them with power and communicate with said electronic tag, and a processing unit controlling the antennas and the circuit for reading electronic tags. The processing unit is configured to activate just one antenna at a time and the reading circuit in order to communicate with said at least one electronic tag, and to locate a position of the electronic tag along the axis according to a number of responses or to a response time from the electronic tag. The invention also relates to the locating method.

Near-field communication surface and method for locating on said surface

A method and a circuit for detecting a binary state supported by an analog symbol, comprising sampling the symbol with a sampling signal based on a frequency having a period shorter than the duration of a symbol, selecting a number of significant samples smaller than the number of samples which would be obtained with a sampling of the symbol at said frequency, and deciding of the symbol state based on the selected samples.

Adaptable demodulator

In some implementations, a mobile device includes a first interface configured to communicably couple to a removable integrated circuit card; a second interface configured to wirelessly communicate with a contactless reader that is external to the mobile device; a communication interface that couples the first interface and the second interface and that is configured to obtain information from an integrated circuit card that is coupled to the first interface in response to receipt by the second interface of an information request from the contactless reader; and a programmable timer that is configured to be started in response to the second interface receiving an information request from the contactless reader, and that is further configured to, upon reaching a programmed value, cause the second interface to transmit the obtained information to the contactless reader.

Managing power and timing in a smart card device

A semiconductor chip has an active face in which an integrated circuit region is implanted. The chip includes an inclined lateral contact pad extending beneath the plane of the active face and electrically linked to the integrated circuit region. An electronic module includes a substrate having a cavity in which the chip is arranged. The module can be applied to the production of thin contactless micro-modules for smart cards and contactless electronic badges and tags.
