Transaction cards having a security cover to selectively obscure transaction information and related methods are disclosed. A transaction card may include a card body having a first layer and a second layer secured to each other, and a cover portion pivotably movable relative to the second layer about a cover rotation axis coplanar with the first layer via a hinge portion, wherein, when in an obfuscation orientation, the cover portion is coplanar with the first layer such that one or more elements of transaction information is obfuscated when viewing the transaction card.

A transaction card construction and a method for making transaction cards provides increased security for transaction card magnetic strips. The transaction card construction includes a card inlay and a clear card body. The card inlay is formed via a lamination press process with the magnetic strip attached to a back surface of the card inlay. The card body may have a window through which a data storage element may be exposed for accessing, such as by a magnetic stripe reader or EMV chip reader. The card body may be formed by adhering the card inlay to the clear card body.

A transaction card and a process of making the transaction card are described. The transaction card includes a core having first and second faces, a core thickness therebetween, and an opening, and embedded electronics disposed in the opening.

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 method and system for programming a smart card using multiple programming protocols in a single card programming station. The card can include at least two programmable chips, with each chip being programmed using a different programming protocol. Alternatively, the card can include a single programmable chip, and the chip is programmed using at least two programming protocols. The card can also include at least two programmable chips, with each chip being programmed using at least two programming protocols.

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 fluid for ink jet printing characters on a substrate that become magnetized in the presence of a magnetic field, the fluid HAVING a suspension of nanoparticles dispersed in a solvent, wherein the fluid comprises a viscosity from 1 to 50 cps and a surface tension of 20-45 dynes/cm, further wherein each nanoparticle is sized between 10-180 nm and comprises M(III).sub.2O.sub.3, M(II)O and M(II)M(III).sub.2O.sub.4, wherein M(III) is a trivalent metal and M(II) is a divalent metal, or Fe.sub.2O.sub.3, MnO and M(II)O, wherein M is a divalent metal selected from the group consisting of Fe, Ni, Mn, Co, Cu, Pt, Au, Ag, Ba and a rare earth metal.

In accordance with aspects of the present invention, a magnetic secured transmission system is presented. A magnetic secure transmission (MST) system can include a full-bridge driver that includes four transistors configured to regulate current through a coil; and a driving controller coupled to drive the full-bridge driver at a high frequency. In some embodiments, the transistors in the full bridge regulator are driven with a high frequency pulsed-wave modulated (PWM) signal to control the current through the coil. A method of magnetic secured transmission (MST) of MST data according to some embodiments includes receiving the MST data; generating coil data in response to the MST data; driving transistors in a full bridge at a high frequency to drive current through a coil according to the coil data.
