Disclosed is an electronic device including: a body; a module enclosed in the body; a microcircuit and a direct current source, both forming part of the body; and an electronic component forming part of the module and accessible from the exterior, the electronic component being electrically connected to the microcircuit and having to be supplied with direct current from the direct current source. The body includes a first antenna connected to the direct current source via an oscillator and the module includes a second antenna connected to the electronic component via a rectifier circuit, the first and second antennas being electromagnetically coupled, providing a wireless radio frequency power supply to the electronic component of the module from the direct current source of the body.

A credit card with an obscurable account identifier. The credit card further comprises a substrate defining a first surface with a chromogenic feature wherein the chromogenic feature is capable of changing from a first state and a second state based on an activating trigger. In the first state, the chromogenic feature appears with a first optical property that obscures the account identifier, and in the second state, the chromogenic feature appears with a second optical property that reveals the account identifier.

An circuit includes a first inductive coil and a second inductive coil each including a plurality of metal traces. The first and second inductive coils are each configured to receive a first signal from an electromagnetic field and generate respective first and second output voltages. Each of the first inductive coil and the second inductive coil are configured to inductively couple to the electromagnetic field. A first circuit element is configured to receive the first output voltage and generate a first response at a first power level of the first output voltage. A second circuit element is configured to receive the second output voltage and transition to an active state to perform one or more functions when the second output voltage exceeds a second power level. The first and second power levels are related to movement of the first and second inductive coils through the electromagnetic field.

A transaction card may include a body having a first part connectable with a second part, and a magnetic stripe on a first main side of the body. A first section of the magnetic stripe is provided on the first part of the body, and a second section of the magnetic stripe is provided on the second part of the body. The transaction card may further include an engagement member extending from the first part of the body for retention within a slot of the second part of the body, the slot embedded within the body between the first main side and a second main side.

A reader for article identification comprises one or more solenoids configured to generate a magnetic field for locally exciting portions of a marker element carrying at least one data feature as the marker element moves through the magnetic field and for causing the marker element to generate a varying magnetic field; and one or more giant magnetoimpedance (GMI) sensors upstream of the one or more solenoids configured to detect the varying magnetic field and produce output based on the varying magnetic field.

A flexible card may include a dynamic magnetic stripe communications device having multiple layers, such as an electromagnetic generator, a magnet, and a shield. A shield may form a non-flexible layer within the stack and may bend, but the shield may not be able to stretch or compress. Flexible layers may surround and adhere to the shield such that when the card is flexed, the flexible layers may stretch and compress with the movement of the shield. The dynamic magnetic stripe communications device may include one or more coils. Each coil may contain a stepped material, such that a length of a lower layer of the stepped material is longer than a length of a middle layer of the stepped material, which is longer than a length of a top layer of the stepped material.

The invention relates to a laboratory device, in particular to a peristaltic pump, having an accessory part, in particular a pump head, that is removably arranged at the laboratory device; and having an apparatus for an automatic recognition of the accessory part from a plurality of accessory parts, in particular mutually different pump heads, removably arrangeable at the laboratory device, wherein the recognition apparatus has a coding at the accessory side and a detection unit for detecting the coding at the laboratory device side.

A transaction card is provided. The transaction card includes a card frame having a card inlay and a card housing. The transaction card also includes a magnetic stripe disposed inside the card frame between the card inlay and the card housing.

A modular transaction card assembly includes a card frame having the traditional dimensions of a credit card, and a transaction card that is smaller than a traditional card and that fits into a receptacle of the card frame. The card frame may include a window in which contact pads of the transaction card are positioned and flush with the surface of the card frame when the transaction card is secured in the receptacle. The card frame and transaction card assembled together may form a uniform assembly that appears and functions as a traditional transaction card (e.g., credit card).

A modular transaction card assembly includes a card frame having the traditional dimensions of a credit card, and a transaction card that is smaller than a traditional card and that fits into a receptacle of the card frame. Each of the card frame and the transaction card may be capable of performing contactless data transactions individually. In some instances, the combined assembly of the card frame with the transaction card may detect a proximity of a mobile device to the assembly and generate an authentication credential that is unique to the combination of the card frame, the transaction card, and the mobile device. The authentication credential may be used to authentic the transaction card when conducting a data transaction.
