Systems and methods are described related to using flexible circuity in a payment device. In one embodiment, a payment device comprises a computing device and a memory. The computing device is configured to store a biometric identifier associated with a transaction account. The computing device is configured to at least receive, by the antenna, an interrogation signal from a point of sale (POS) device in order to activate the payment device for a payment transaction. The computing device is configured to determine a scanned fingerprint identifier of a user based at least in part on the interrogation signal activating the payment device and authenticate the scanned fingerprint identifier by matching the scanned fingerprint identifier to the biometric identifier. The transaction account is transmitted to the POS device for processing the payment transaction based at least in part on the authentication of the scanned fingerprint identifier.

A method for removing an EMV chip from a plastic credit card or debit card and placing the removed EMV chip onto a metal card, includes heating the plastic credit or debit card containing the EMV chip to loosen the EMV chip, the EMV chip being substantially square and planar, the EMV chip having an upward top face, a downward bottom face, and four sides; removing the loosened EMV chip from the plastic credit or debit card; bending the four sides of the EMV chip towards the downward bottom face of the EMV chip; applying an adhesive coating to the bottom face and the bended four sides of the EMV chip; and placing the adhesive coated bottom face and bended four sides of the EMV chip into a holding cavity of the metal card.

A transaction card construction and computer-implemented methods for a transaction card are described. The transaction card has vector-formatted visible information applied by a laser machining system. In some embodiments, systems and methods are disclosed for enabling the sourcing of visible information using a scalable vector format The systems and methods may receive a request to add visible information to a transaction card and capture an image of the visible information. The systems and methods may capture data representing the image. The systems and methods may also determine an ambient color saturation of the image. Further, systems and methods may translate the image based on the ambient color saturation of the image. The systems and methods may also map the translated image to a bounding box and convert the mapped image into vector format. In addition, the systems and methods may provide the converted image to a laser machining system.

Systems and methods for overmolding a card are provided. A chip fraud prevention system include a device including a chip and a substrate. The chip may be at least partially encompassed in a chip pocket, and the substrate may be at least partially encompassed by the overmold.

A method for processing transaction data, implemented by a communications terminal having a touch screen. The method includes: detecting a necessity of entering a piece of personal identification data; transmitting to a card reader connected to the communications terminal a request for supporting a display of a virtual keypad, the request comprising a piece of data representing a passage of the communications terminal from a “master” mode to a “slave” mode of operation, the slave mode leading to implementation of the method for processing transaction data under the exclusive control of the card reader; of entry, by the user on the virtual keypad, of the piece of personal identification data; and receiving, from the card reader, the piece of personal identification data.

Various switchable devices including inductive antennas are disclosed. These switchable devices may include one or more RFID tags and one or more switches. Some of these one or more switches are optionally wireless and/or manual. In various embodiments, the switchable devices include are included within cellular phones, security devices, identity devices, financial devices, remote controls, and the like. The switchable devices are optionally configured to perform financial transactions.

A contactless card with power harvesting unit is described. The power harvesting unit is configured to harvest power from near field communication radio wave fields and supply power to a memory, processor, and communication circuit of the contactless card. In some embodiments, the contactless card may also include a capacitor for smoothing out power deliver or a rechargeable battery. The contactless card is configured to establish two-way communication with a secondary device and to store and execute applets. In some embodiments, the contactless card is a payment card which contains information associated with a primary profile and a secondary profile. The secondary profile may be activated using two-way communication if the primary profile is deactivated due to fraudulent activity.

An electronic payment card includes a payment card substrate having opposed top and bottom faces. An EMV chip is disposed at a location on one of the top and bottom faces of the payment card substrate. The EMV chip is a donor EMV chip removed from a donor electronic payment card on which the donor EMV chip was previously disposed.
