The present disclosure provides a financial card with function of fingerprint verification and a working method therefor, which belongs to information technology field The financial card with function of fingerprint verification includes: a waiting and receiving module (401), a determining module (402), a storing module (403), a first sending module (404), a second sending module (405), a third sending module (406), an application cryptogram module (407) and a fourth sending module (408). The financial card provided by the present disclosure further includes a cardholder verifying module and/or a boot-up verifying module The solution provided by the present disclosure improves security of the identity verification in an e-transaction and makes the e-transaction to be more convenient by using the fingerprint to execute identity verification.

A system for securely updating an electronic transaction card held by an account holder with an additional account and/or account data is described. A dynamic transaction card may be securely updated with an additional account by using pre-stored shell data and/or inactive data, whereby the pre-stored shell data may be populated using data received from an issuer system and/or the inactive data may be activated via an activation signal received from a mobile device. A backend server may determine, via a fraud determination, expiration determination, and/or user-request, that new account data should be transmitted to an account holder. The dynamic transaction card may receive the data associated with a notification, update a display, instruct an EMV applet to use a key associated with a received EMV key identifier for signatures, and/or update any additional data stored on the dynamic transaction card.

Various embodiments are generally directed to enhancing a card activation experience for an authorized card user when activating a new card by at least displaying various types of information related to the new card in augmented reality (AR) and allowing the user to perform the activation itself or experience other aspects of the activation process in AR. Information pertaining the successful activation of the card may also be provided to the user in AR.

A Digital Payment Device (DPD) including a Digital Transaction Processing Unit (DTPU), a Microcontroller Unit (MCU), and a command generation unit, wherein the command generation unit is operable to generate a DTPU command capable of being authenticated against a targeted security domain of the DTPU, the DTPU command including a payload capable of being executed by the DTPU; and the MCU is operable to communicate the DTPU command to the DTPU for execution by the DTPU.

Provided is a biometric data registration system, which displays screen data for causing a user to select whether a destination of registration of the user's biometric data is a card for payment or a registration destination server device, accepts from the user a selection of the destination of registration, and acquires the user's biometric data.If the selection indicates the card for payment, the biometric data registration system stores the biometric data in a first storage unit which is for managing data which is stored in a storage medium of the card for payment, whereas if the selection indicates the registration destination server device, the biometric data registration system stores the biometric data in a second storage unit which corresponds to the registration destination server device.

A program for running on a processor of a portable payment device is adapted for carrying out a payment interaction and permitting ticket storage in a memory of the portable payment device. The program is configured to interact with an access point and includes a set of instructions, a first code portion and a second code portion. The set of instructions, when executed by the processor, causes the portable payment device to perform the steps of: responsive to a first message from said access point, executing the first code portion; and responsive to a second message from the access point, executing the second code portion. The first code portion includes first instructions corresponding to the payment interaction. The second code portion includes instructions corresponding to the payment interaction and second instructions corresponding to the ticket interaction.

Systems and methods for authentication may include a first device having an association with a first account, including a memory containing one or more applets, a counter value, and transmission data, a communication interface, and one or more processors in communication with the memory and communication interface. The first device may create a cryptogram based on the counter value, wherein the cryptogram includes the counter value and the transmission data. The first device may transmit, after entry of the communication interface into a communication field, the cryptogram, and update, after transmission of the cryptogram, the counter value. The first device may receive, via the communication interface, one or more encrypted keys and one or more parameters. The first device may decrypt the one or more encrypted keys and, after decryption of the one or more encrypted keys, switch an association from the first account to a second account.

A dynamic transaction card that includes a number of layers, each of which may be interconnected to one another. For example, a dynamic transaction card may include an outer layer, a potting layer, a touch sensor layer, a display layer (including, for example, LEDs, a dot matrix display, and the like), a microcontroller storing firmware, Java applets, Java applet integration, and the like, an EMV chip, an energy storage component, one or more antenna (e.g., Bluetooth antenna, NFC antenna, and the like), a power management component, a flexible printed circuit board (PCB), a chassis, and/or a card backing layer. The card includes a secure element to receive visual impairment settings and alert data. A microprocessor can convert the alert data into impairment data based on the visual impairment settings. A display is generated based on the impairment data.

Implementations of a smart card comprising a single smart card for multiple uses which has a number of separate areas that are accessed by one code are provided.

A method, at a mobile device, of assigning a preferred payment application stored on the mobile device to a merchant, the method comprising the steps of: receiving a selection of a merchant at the mobile device; receiving a selection of a preferred payment application; and mapping the payment application to the merchant by creating a record containing an application identifier and a merchant identifier.
