In one embodiment, the method comprises generating a trusted artifact with a forward immutable continuous integration (CI) implemented as a build pipeline, wherein the artifact comprises updated software comprising payment processing code with an EMV vector kernel for processing of EMV-based card present transactions; and in response to the software update, performing end-to-end testing of EMV card present transactions using code commits from one or more code repositories, wherein the end-to-end testing comprises executing the code commits that includes executing payment processing code for processing EMV-based card present transactions with an EMV vector kernel and one or more emulated EMV cards, and running tests against the executing code commits to validate behavior the payment processing code including the EMV vector kernel, wherein the tests comprise running one or more emulated EMV cards against the vector kernel as part of one or more emulated EMV-based card present transactions and monitoring communications related to the one or more emulated EMV-based card present transaction communications.

A wireless transmit/receive unit, WTRU, can select a constellation from a set of constellations corresponding to a symbol configuration for indirect carrier modulation, ICM, based on at least one constellation performance efficacy indicator, each constellation performance efficacy indicator respectively corresponding to a constellation of the set of constellations, and use the selected constellation and symbol configuration to simultaneously harvest energy and transmit data.

An RFID device is provided for communicating with at least one RFID transponder that has a transmitter, a receiver, a transmission antenna and a reception antenna for emitting and receiving RFID signals and has a control and evaluation unit that is configured to transmit and receive an RFID signal in a respective one of a plurality of frequency channels, in particular to encode RFID information into the RFID signal and/or to read information from the RFID signal in accordance with an RFID protocol and to carry out an intensity adaptation of the RFID channel in dependence on the frequency channel used for the transmission and reception.

Shelf rail for an electronic shelf-label system, wherein the shelf rail comprises a first fastening structure for fastening at least one electronic shelf label that can be supplied with power in a contact-free manner, in particular, an electronic shelf-label display, wherein the first fastening structure comprises a wall running between a head area and a foot area of the shelf rail with a wall front side and a wall back side, which is used to define a shelf-label plane with its wall front side for the positioning of the at least one shelf label along the wall, and wherein the shelf rail on the wall back side comprises at least one second fastening structure, which is tubular or channel-shaped in particular, for attaching at least one conductor loop on a conductor-loop plane, wherein the conductor-loop plane is aligned parallel to the shelf-label plane and runs at the defined first distance from the shelf-label plane, and wherein the shelf rail comprises a third fastening structure for fastening a conductive structure, in particular, a planar structure, at a defined second distance from the conductor-loop plane.

In a card reader, an interfering magnetic field generation mechanism 11 includes a core part 14a, a core part 14b, and a core part 15a, each of which is formed of soft magnetic material in a straight line, a coil 16 that is wound around the core part 14a, a coil 17 that is connected to the coil 16 in series and is wound around the core part 14b, a coil 18 that is wound around the core part 15a, a first drive circuit that supplies alternating current to the coils 16 and 17, and a second drive circuit that supplies alternating current to the coil 18. The core part 15a is disposed between the core part 14a and the core part 14b. The core part 15a is formed independently of the core parts 14a and 14b, and is separated from the core parts 14a and 14b.

A system for prevention of electrostatic discharge from a payment card to a point of sale (POS) device comprising an integrated circuit card (ICC) socket, includes a spring member comprising a first end electrically coupled to a second end. The first end is electrically coupled to an electrical ground, the first end is mechanically coupled to the POS device, and the second end is positioned for contact with a top edge of the payment card. When the payment card is inserted into the ICC socket and the top edge comes into contact with the second end, the first end and the second end form a first electrical path for electrostatic discharge between the payment card and the electrical ground.
