A processor of a computing device may receive, from a contactless card, a uniform resource locator (URL) and a cryptogram. An operating system (OS) executing on the processor may open an application based on the URL. The application may transmit the cryptogram to an authentication server. The application may receive, based on the server verifying the cryptogram, an account number. The application may store the account number in a memory of the device.

A transaction card receives sound waves that represent a user command, where the user command identifies one or more transaction restrictions of the transaction card. The transaction card converts the sound waves to a digital signal and identifies, based on an analysis of the digital signal, user command data that identifies the user command. The transaction card sets, based on identifying the user command data, one or more transaction restriction values for the one or more transaction restrictions. The transaction card receives transaction metadata associated with a transaction and determines whether the transaction is compliant with the one or more transaction restrictions. The transaction card causes, based on determining whether the transaction is compliant with the one or more transaction restrictions, the transaction to be processed by a server device, or to be declined.

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.

Systems and methods are provided for use in processing transactions based on biometric data used in connection with authenticating consumers to payment accounts to which the transactions are directed. One exemplary method includes prompting a consumer to provide a biometric in connection with a transaction by the consumer, and receiving a payment account credential specific to a payment account for use in the transaction. The method also includes appending a biometric score and an indication of a biometric technology used to capture the biometric to an authorization request associated with the transaction, and transmitting, by the computing device, the authorization request to an issuer.

A self-authenticating chip includes first and second memory regions storing, respectively, first and second authentication codes. The second memory region is adapted to be unreadable and unmodifiable by the chip or a chip reader. The chip also includes a comparator for providing an indicator of whether given input matches the second authentication code. The chip also includes an authentication circuit that is operable to read the first authentication code from the first memory region, present the first authentication code to the comparator, and in response to receiving an indicator from the comparator indicating that the first and second authentication codes match, unlock at least one of (i) a communication interface of the chip to allow data to be transmitted therethrough to a chip reader and (ii) a third memory region of the chip to allow data to be read therefrom.

A system and method is provided for generating a sensory indication on a transaction card, whereby a user is rewarded with a visual, audial, haptic, or olfactory experience. The method comprises executing a purchase transaction on the card, the transaction relating to an event, charging a power source on the card, receiving an input signal by the card, the signal indicating an output indication relevant to the event, and generating an output signal using power from the power source, based on the input signal. The card comprises a security component enabling a purchase relating to an event, a power source receiving charging energy at the time of the purchase, an input component receiving an input signal comprising information specifying a desired indication relevant to the event, an output component for generating the desired indication, one or more memories storing instructions and one or more processors executing the instructions to perform the method.

A smart card includes a plurality of display devices on an outside surface of a housing. Circuitry within the housing includes a processor, and communication circuitry configured to communicate with at least one computing device located within a geographic region around the smart card. The processor is configured to continuously receive a plurality of communication signals from the computing device, to continuously assess a geographic distance from the smart card to the fixed position of the computing device within the geographic region using the plurality of communication signals, to continuously activate or deactivate the plurality of display devices based on the geographic distance from the smart card to the fixed position of the computing device in the geographic region for providing a user with a directional indication, distance indication, or both, to the computing device in the geographic region.

Various embodiments are generally directed to techniques to perform transaction with transaction cards utilizing characteristics of customer's signature. Techniques may further include determining characteristics of a signature including a reduced set of data points for the signature and storing the characteristics in secure memory of transaction card. The transaction card including the characteristics are used to perform transactions, such as those performed at Point-of-Sale (POS) terminals.

Provided are approaches for providing multiple user accounts in a same transaction card assembly. The transaction card assembly may include a first card including a first card first side opposite a first card second side, the first card first side including a first pair of magnetic stripes and the first card second side including a first pair of identification chips. The transaction card assembly may further include a second card coupled to the first card, the second card including a second card first side opposite a second card second side, the second card first side including a second pair of magnetic stripes, and the second card second side including a second pair of identification chips. The first and second cards are slidable relative to one another between multiple positions to selectively expose and cover each identification chip of the first and second pairs of identification chips.

A credential authorization device having a first fingerprint sensor, configured to detect first sensor data representing one or more elements of a finger from a first person in contact with the first fingerprint sensor; a second fingerprint sensor, configured to detect second sensor data representing one or more elements of a finger from a second person in contact with the second fingerprint sensor; and one or more processors, configured to determine an authorization for a transaction based on an authentication of the first sensor data and the second sensor data.
