A device, including a main element and a set of at least two auxiliary elements, said main element including a master SWP interface, each auxiliary element including a slave SWP interface connected to said master SWP interface of said NFC element through a controllably switchable SWP link and management means configured to control said SWP link switching for selectively activating at once only one slave SWP interface on said SWP link.

There is provided a method including generating an initial token being associated with a given context, and sending the initial token to a destination device. The method also includes receiving a scanned token generated by a mobile device scanning an output of the destination device. The output may be generated based on the initial token. In addition, the method includes authenticating the scanned token by comparing the scanned token to the initial token. Furthermore, the method includes generating a productivity indicator based on the scanned token, and outputting the productivity indicator.

Various aspects of the disclosure generally relate to security for a credit card processing reader. Part of security for a reader is a secure cover having a trace mesh to discourage drilling through the cover. The mesh may be connected to one or more landing areas on the cover. The landing area has electrical pads with trace routing that provides tamper protection for the landing area.

The present embodiments relate generally to methods for providing viewing access to an ultrasound image feed generated at an ultrasound imaging machine. A multi-use display device may form a first link-layer connection with the ultrasound image machine for transmitting commands that control imaging parameters of the ultrasound image feed. The multi-use display device may then: determine link-layer connection parameters that allow the ultrasound imaging machine to form a second link-layer connection with a receiving device (the receiving device having no link-layer connection with the ultrasound imaging machine), and provide the connection parameters to the receiving device. The ultrasound imaging machine forms a second link-layer connection with the receiving device, based the connection parameters. The second link-layer connection is then used for receiving, at the receiving device, the ultrasound image feed controlled by the multi-use display device.

Disclosed is a method for determining a type of an object arranged in a radio frequency, RF, field transmitted by an NFC reader device. This method involves analyzing the oscillatory behavior in the NFC reader device, after the RF field transmitted by the reader has been switched off, using a decomposition scheme with a degree M for decomposing a decay signal trace into M superimposed components. The method involves predetermining the decomposition scheme with a degree M for decomposing a decay signal trace into M superimposed components, e.g. weighted oscillation components, wherein each one of said M superimposed components is defined by a predetermined superimposition function, which in turn is determined by an associated set of characteristic parameters, and storing, e.g. in a database that is accessible for the P&E unit, an indication of the decomposition scheme and the M predetermined superimposition functions.

Example embodiments of the present disclosure include a system comprising a computer-readable storage medium storing at least one program and a computer-implemented method for providing an interactive graphical user interface (GUI) on an interactive mirror display responsive to user interest. Consistent with some embodiments, the method may include identifying an item of interest to an individual in a retail store and accessing detailed product information for the item from a product database. The method may further include generating the interactive GUI using the detailed product information and causing the interactive GUI to be presented to the individual on the interactive mirror display.

A circuit for an NFC chip is described herein. According to one exemplary configuration, the circuit comprises an antenna for near field communication, an antenna resonant circuit which has an adjustable resonant frequency, a temperature sensor and a controller circuit coupled to the temperature sensor. The controller circuit is designed to change the resonant frequency of the antenna resonant circuit according to a temperature sensor signal provided by the temperature sensor.

An electronic tag, which may be used in a data management system, comprises a Bluetooth transmitter and an RFID transmitter. The Bluetooth transmitter is operable to transmit first data packets. The RFID transmitter is operable to transmit second data packets. The first data packets comprise a first identifier, ID1, and the second data packets comprise a second identifier, ID2, which is different from ID1. A portable electronic device is configured to, upon receiving one of the first data packets by a Bluetooth receiver, selectively activate an RFID receiver for the second data packets, thereby enabling transfer of ID2 from the electronic tag irrespective of the data transfer capacity of the first data packets.

A method for performing a card-to-card direct contactless transaction between a first active smart card and a second active smart card, each comprising an active near-field communication (“NFC”) reader. The method may include activating the first active smart card by receiving input of a personal identification number (“PIN”) on a keypad located on the first active smart card, verifying the PIN and further receiving input of a transaction amount on the keypad. The method may further include initiating a wireless NFC communication to perform the transaction by positioning the first active smart card within a pre-determined distance to the second active smart card and confirming accuracy of each of the first and second active smart card using the active NFC reader to retrieve card ID data and confirm accuracy. Following confirming, the method may include completing the transaction using the first active smart card and a payment network.
