A home system can include a central control unit, which can be paired with a plurality of accessory devices including a client device. The client device can receive an instruction signal from a contactless card. An application of the client device can process the instruction signal and generate an event signal. The client device can transmit the event signal to the central control unit and the central control unit can transmit a device signal to one or more of the accessory devices. The device signal can instruct the one or more accessory devices to perform one or more tasks.

A smart card with secure and efficient image capture and analysis is provided. The card may include a non-transitory memory embedded in the housing storing computer-executable instructions. The instructions, when run on the microprocessor, are configured to capture, via the camera, an image of a building (or other suitable image), process the image via an image processing module, determine, based at least in part on the processing of the image, a payment amount and a payment recipient associated with the building. The smart card may also display payment information on the display screen. The payment information may include the payment amount and/or the payment recipient. When authorization is received via a tactile sensor, the card may execute a payment or other communication, over a payment gateway from an account associated with a user of the platform to an account associated with the payment recipient.

In certain embodiments, location-based activation of card identifiers may be facilitated. In some embodiments, an electrophoretic display card may store a set of location-specific card identifiers, where each card identifier of the set is associated with (i) an account of a user and (ii) creation location information indicating a device location of the user at a creation time of the card identifier. In response to being powered by a user device, the card may initiate wireless communication with the user device. The card may determine a device location of the user device, select a card identifier from the set of card identifiers that matches the device location, and switch a state of the card identifier to an active state to enable transaction processing for the card identifier. In some embodiments, the card may cause the active card identifier to be presented on an electrophoretic display of the card.

Example embodiments of systems and methods for contactless card verification include a contactless card including a substrate, a processor, and a memory, wherein the memory contains a first applet and a second applet, and a recipient device in data communication with the contactless card, wherein the second applet is configured to retrieve one or more parameters from the first applet via an interface; and wherein the second applet is configured to transmit the one or more parameters to the recipient device for verification.

Systems and methods for autonomous payment routing are provided. A method may include storing in a smart card a database of contacts accessed from a digital contact directory. The method may include receiving a request to reroute a payment via an alternate payment channel, the payment including a recipient and an amount, and the alternate payment channel originating from an account associated with one of the contacts in the database. The method may also include resolving, via a wireless communication element that is embedded in the smart card, routing information for the account. The method may also include transmitting, to an administrator of the account, a request for authorization to reroute the payment, and, when authorization is received, executing the payment via the alternate payment channel.

Systems and methods for verifying users in connection with transactions using biometric payment card devices are disclosed. One exemplary biometric payment card device generally includes a card body, a fingerprint sensor, a modem, and a processor coupled to the modem and the fingerprint sensor, where each of the fingerprint sensor, the modem, and the processor are disposed on the card body. The processor of the payment card device is configured to capture, via the fingerprint sensor, a fingerprint of a user associated with the payment account, compare the captured fingerprint to a reference fingerprint stored in memory in communication with the processor, and then compile and transmit, by the modem, an authentication result to an issuer of the payment account and/or a payment network associated with the payment account in response to the user being authenticated, or not, based on the comparison of the captured fingerprint and the reference fingerprint.

A method for contactless payment relay attack protection includes receiving an online authorization request including a cryptogram, a measured processing time, and a reference processing time from a terminal. The cryptogram is verified, and a determination is performed as to whether the measured processing time exceeds the reference processing time. An online authorization response authorizing or declining a monetary transaction is transmitted, based on the determination. An artificial intelligence transaction analysis can be performed based on past and current conditions (e.g., battery level, operating system, open applications) of a payment device such as a mobile phone, past and current conditions of a terminal, and/or a monetary amount. The online authorization response can be based on the artificial intelligence transaction analysis.

Systems and methods for secure and efficient bill capture, analysis, and execution are provided. A method may include capturing, via a camera embedded in a smart card, an image of a bill. The bill may include a plurality of text fields. The method may include processing the text fields via a microprocessor embedded in the smart card. The method may include determining, based at least in part on the processing of the text fields, a balance amount and a payment recipient associated with the bill. The method may also include executing a payment for the balance amount from an account associated with a user of the smart card to an account associated with the payment recipient. The executing may be performed via a wireless communication element embedded in the smart card which may be configured to provide wireless communication between the smart card and a payment gateway.

Controlling communications between arrangements of computing systems improves letter of credit (“LC”) administration, speed, flexibility, and reach. The computing systems can be operated by an Applicant, Issuer, Custody Bank, and Beneficiary. LC improvements are achieved by the Applicant computing system making a LC request to the Issuer computing system, which obtains a hold on non-cash collateral and provides the hold to the Custody Bank computing system, designating the Custody Bank as both nominated person and paying agent. The Custody Bank computing system obtains a hold on the collateral, using it to immediately act on Beneficiary payment requests in kind of the collateral. Under these arrangements, the LC is capable of immediate payment and automated amendments to Stated Amounts to rebalance capacity amongst Beneficiaries of the Applicant, the LC Stated Amount and collateral values are always equal, and the LC is less susceptible to payment interference, automatic stays, and double payment.

A home system can include a central control unit, which can be paired with a plurality of accessory devices including a client device. The client device can receive an instruction signal from a contactless card. An application of the client device can process the instruction signal and generate an event signal. The client device can transmit the event signal to the central control unit and the central control unit can transmit a device signal to one or more of the accessory devices. The device signal can instruct the one or more accessory devices to perform one or more tasks.
