Embodiments of the present disclosure provide a device, system, methods and components related to a modular card. Example components of the modular card include a thin rectangular rear plate, a thin rectangular front plate overlying the rear plate, a first plurality of fasteners fixed to the thin rectangular front plate, a second plurality of fasteners fixed to the thin rectangular rear plate, the second plurality of fasteners being configured to be removably engaged with the first plurality of fasteners; a magnetic strip, and/or an integrated circuit. In operation a user may remove and/or replace various components to customize the modular card. Some customizations include altering the accounts to which the modular card relates. In some example, the modular card may include components which relate to different accounts.

A transaction card package assembly comprising at least one transaction card, at least one sample product, and a card holder, and methods and system for processing the same.

A building element (for example plasterboard) is described, and comprises a wirelessly or magnetically readable identifier. Since the identifier is wirelessly or magnetically readable, it is possible to determine the type of the plasterboard (or other building element) after installation, without damaging the plasterboard or any decoration applied to it.

A fluid treatment cartridge includes a housing having a fluid inlet and a fluid outlet with a treatment media contained within the housing. The fluid treatment cartridge includes a detection member comprising at least one closed electrically conductive loop having at least two spatially separate sections. Each of the sections generates a magnetic response when at least one section is electromagnetically excited. The magnetic response of each section is predetermined by the physical shape of the section and comprises at least one of a predetermined magnetic phase response and a predetermined magnetic amplitude response. The predetermined magnetic response of at least one other section of the closed electrically conductive loop corresponds to at least a one digit code.

Laminated cards with user interfaces are provided. The user interfaces can have enhanced tactile feel. In one embodiment, a card may be constructed to have a dual-layer user interface. In another embodiment, a card may be constructed to include a support structure. In yet another embodiment, a card may include a relatively soft material that covers at least a portion of the user interface. In yet another embodiment, a card may include a user interface that is fluidically coupled to a bladder. In a further embodiment, a card can include any combination of a user interface, which may be a dual-layer user interface, a support structure, a soft material that at least partially covers a user interface, and a bladder.

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.

The invention concerns a security element having a magnetic coding consisting of magnetic coding elements. At least one of the magnetic coding elements has a grid-shaped magnetic region which is formed by a plurality of mutually parallel grid strips made of magnetic material which respectively have a magnetic anisotropy. The grid strips lead, through their magnetic anisotropy, to the magnetization direction of the coding element being able to differ from the direction of the applied magnetic field. Since the resultant magnetic signals that the grid-shaped magnetic regions deliver cannot be simulated by conventional magnetic regions, said coding elements increase the anti-forgery security of the security element.

Systems and methods for authenticating a product using a magnetic code are disclosed. The systems and methods include detection of a magnetic code on the product using a device comprising a magnetometer, correlating the detected magnetic code to a symbolic code, determining whether the symbolic code matches a symbolic code stored in a database, and receiving, by the device, a signal indicating that the product is authentic if the symbolic code matches a symbolic code stored in the database.

A magnetic secure transmission (MST) system includes a switching circuit, an inductor, and a control circuit. The control circuit is configured to control the switching circuit to adjust a level of current in the inductor. The inductor current may be adjusted by a first amount over a data transmission period such that the inductor emits a magnetic pulse including a first magnitude. The inductor current may be kept constant during a first sub-period of a data non-transmission period and may be changed by a second amount at a constant slope during a second sub-period of the data non-transmission period, such that the inductor emits a magnetic pulse including a second magnitude during the second sub-period of the data non-transmission period. The second amount is less than the first amount. The first magnitude is greater than a threshold value. The second magnitude is less than the threshold value.
