A flexible card may include a stacked dynamic magnetic stripe communications device having multiple layers, such as a magnetic emulator, 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.

A method for designing and constructing a thin programmable dynamic credential card is disclosed. The thin programmable dynamic credential card may comprise multiple layers, including a top surface layer containing an opening through which a graphical display system below the top surface layer can be viewed. The graphical display system is configured to present at least one coded image. The at least one coded image is determined based at least in part on context data associated with a context of the programmable credential card.

Systems and methods for associating a proxy card with an electronic wallet are disclosed. A computer implemented method may include receiving an authentication information of a proxy card, and associating the proxy card with an electronic wallet, wherein associating the proxy card with the electronic wallet allows secure access to the electronic wallet when the proxy card is presented at a point of sale. A system may include a proxy card comprising authentication information, and an electronic wallet associated with the proxy card, wherein the association of the electronic wallet with the proxy card allows secure access to the electronic wallet when the proxy card is presented at a point of sale. A wallet redemption card may comprise a rewriteable magnetic stripe, a smart chip, a wireless communicator operably connected to the smart chip, and an interface operably connected between the rewriteable magnetic stripe and the smart chip.

An embodiment includes a multi-function electronic device capable of generating a programmed magnetic field of alternating polarity based on a speed of a card swipe, and methods for constructing the device for the purpose of emulating a standard credit card. An apparatus is described to allow the device to emulate behavior of a credit card when used in electronic credit card readers. Additionally, methods are described to allow user control of the device for the purpose of authorizing or controlling use of the device in the application of credit, debit and cash transactions, including cryptocurrency and device-to-device transactions. Methods are also described for generating a limited-duration payment number when performing a transaction for the purpose of creating a limited-use payment number, which is limited in scope of use to a predetermined number of authorized transactions. Furthermore the device may interact with other similar devices in proximity for the purpose of funds or credit/debit transfers.

Methods and apparatus for enabling a proximity payment device to generate dynamic data for securely conducting a transaction by emulating a magnetic stripe payment card. In an embodiment, a mobile device processor transmits information to a digital enablement service computer to activate a simulated magnetic stripe payment wallet application stored in the mobile device. The mobile device then receives one or more cryptographic keys, generates an unpredictable number (UN), generates dynamic CVC3 data based on the UN, and then assembles emulated magnetic stripe data. During initiation of a purchase transaction, the mobile device processor transmits the emulated magnetic stripe data to a communications interface associated with a merchant device.

A method for the transmission of data to a magnetic read head of a payment terminal. The method is implemented by an electronic device capable of generating a magnetic field representative of an encoding of the data to be transmitted, and the transmission of the data includes a plurality of emissions of a same sequence of standardized data. The standardized data is data representative of a payment means and is formatted according to the ISO/IEC 7813 standard. The method further includes transmitting secondary data that are emitted between two successive emissions of the sequence of standardized data.

Advanced loyalty applications are provided to improve the functionality of cards and devices. For example, a user interface may be placed on a card (e.g., a physical button) or a telephonic device (e.g., a virtual button on a capacitive touch screen). Manual input provided to this user interface may, for example, cause a non-merchant product (e.g., insurance) to be purchased with a merchant purchase. The product can be paid for with debit, credit, gift card balance, or points. A code indicative of a user's desire to purchase the product may be communicated to a payment card reader (e.g., to a magnetic stripe reader via a magnetic stripe communications device). A display may be provided next to a button to allow a user to scroll, or toggle by pressing the button repeatedly, through different products (which may be merchant or non-merchant products).

A credit card shaped element with a dynamic stripe which may be activated or deactivated, where the stripe is formed by a plurality of coils provided along the curve thereof, where the plurality of coils are activated in a sequential manner, where a plurality of proximity sensing coils are provided in series along the curve thereof, where the plurality of coils are formed by one coil contacted at multiple positions along its length by contact pads and where the signals fed to the coils cause an output of a reader coil to output a signals with a minimum slope or where one signal fed to one track has no peaks when the other signal is close to zero.

Provided are a multi-function card that has a non-contact IC card function, a magnetic stripe card function, and a function of generating a magnetic card signal and an NFC signal, a Bluetooth function capable of transmitting a signal to devices such as smartphones, includes a metallic frame, and is robust against bending or breakage, a transmission/reception sensor system used for the multi-function card or the like, and a wearable device, and the transmission/reception sensor system includes a magnetic sensor 10 including a coil 2 wound around a magnetic sensor core 1, an NFC coil 12 formed in a planar shape, and a metallic frame 13a of a loop shape which is installed along the NFC coil 12 and includes one or more cut portions.

A mobile computing device for transmitting token data to a key card reading device having an activation mechanism is provided. The computing device is programmed to receive token data representing access data of a key card, generate a transmission signal representing the access data of the key card based on the token data in response to receiving the token data, and output the transmission signal to the key card reading device. The access data causes the key card reading device to activate the activation mechanism. The transmission signal causes the key card reading device to activate the activation mechanism when the mobile computing device is placed near the key card reading device and the transmission signal is authenticated by the key card reading device.
