Described is a system (SY) comprising a card (DV1) and a peripheral device (DV2) configured to cooperate together to enable a biometric print to be acquired. The smartcard (DV1) includes a biometric print sensor (10) and a control module for transmitting control signals (SG) to the peripheral device (DV2), each control signal (SG) being defined by a respective single level of an electrical characteristic. Apart from a possible internal power supply, the peripheral device (DV2) may include passive components only, including a user interface (20) configured to put itself into a predetermined state in response to each received control signal (SG), so as to guide a user in acquiring a biometric print by means of the biometric print sensor (10).

A system includes one or more memory devices storing instructions, and one or more processors configured to execute the instructions to perform steps of a method. The system may receive an authentication request from a computing device and determine whether the authentication request corresponds with stored authentication data. Based on the determination, the system may store identification data associated with a smart device corresponding to the authentication request. The system may receive detection data when the smart device is detected within a predetermined area and, in response to a detection, obtain an identifier from the smart device. The system may determine whether the obtained identifier corresponds with the stored identification data. Based on the determination, the system may direct an electronic lock to transition from a locked state to an unlocked state.

Aspects described herein may allow for method of detecting when a payment card is in a retail establishment by establishing communication between the payment card and a real-time position tracking system; determining whether one of a plurality of accounts linked to the payment card has been used in one or more prior purchasing transactions in the retail establishment; detecting, movement of the payment card with respect to the individual carrying the payment card while the payment card is in a carrying device carried by the individual; and providing, by the payment card, haptic feedback and visible feedback to the individual carrying the payment card.

A transaction card is provided. The transaction card can include a top layer, a first intermediate layer, a middle layer, a second intermediate layer, and a bottom layer. Contact pads can be disposed in the top layer and bottom layer and can be electrically connected to each other via the first intermediate layer, the second intermediate layer, and the middle layer to provide an electrical connection to the same chip. At least one of the contact pads can be coupled to an integrated chip disposed between the top layer and the bottom layer.

Systems and methods involving biometric authentication of transaction cards including aspects of exception handling, deactivation and other features are disclosed. In one embodiment, an exemplary implementation may involve generating a first user interface having one or more interactive UI elements that enable a card owner to manage a plurality of features associated with a transaction card, and determining, if a biometric-activated control is enabled and the vendor is not excluded from the biometric-activated control, whether the transaction card is biometrically-active. Further, the interactive UI elements may include elements such as a first UI element that is configured to allow the card owner to enable a biometric-activated control of the transaction card, and/or a second UI element that is configured to allow the card owner to exclude one or more vendors from the biometric-activated control.

Various embodiments are generally directed to secure generation of barcodes using cryptographic techniques. An application may receive a request to generate a barcode. The application may receive encrypted data from a communications interface of a contactless card associated with an account. The application may receive, from a server, verification of the encrypted data and an encrypted authorization token associated with the account. The application may generate the barcode utilizing the encrypted authorization token.

Methods are provided for authenticating an initiator of a transaction during processing of the transaction. Methods may include initiating a transaction, including transaction details, at a transaction initiation node. Methods may include transmitting the transaction to a processing entity. Methods may include identifying that the transaction is above a threshold of anomalous transactions based on historic transactions associated with the transaction details. Methods may include transmitting an authorization request from the processing entity to a payment card linked to the transaction details. Methods may include receiving the authorization request at the payment card. Methods may include approving and/or denying the authorization request at the payment card. Approving and/or denying the request may include input of a signature and/or biometric. Methods may include transmitting the approval and/or denial from the payment card to the processing entity. The processing entity may transmit the approval and/or denial to the transaction initiation node.

Disclosed are various embodiments for predicting and customizing round-ups for various types of transaction. First, a computing device can access adjustment criteria for a user profile. The computing device can then generate an event listener configured to monitor events made in association with the user profile. When events are accessible by the event listener, the events are filtered or otherwise analyzed to identify a subset of the events that comply with the adjustment criteria. Individual ones of the events in the subset are adjusted by performing a round-up operation. The round-up operation can include adjusting a transaction amount by a predetermined amount and depositing the predetermined amount into the destination account.

A physical card (in some cases without any on-board source of power or computing capabilities) is configured to maintain access information for digital bearer assets. The physical card may include disposed thereon a single address operable to receive digital bearer assets in one or more transactions on a decentralized computing platform, like a blockchain-based decentralized computing platform. Other decentralized computing platforms utilize different address generation protocols, thus preventing use of a single address on those other platforms. A set of addresses is generated, each address corresponding to a given decentralized computing platform. Each address is based on a same underlying key-pair, and a primary address is selected from the set for a given card. The remaining addresses in the set are stored, without storage of the public key or private key, and returned in a response to a request for additional addresses of the currency card.
