The disclosure includes systems and methods for disabling a payment function of a transaction card. The system receives payment account data from a transaction card and transmits a payment authorization request message to a card issuer associated with the transaction card. The system receives, from the card issuer, an authorization request response message. The authorization request response message declines the transaction and includes a status response code corresponding to a status of the transaction card. The system determines whether the status response code indicates that the transaction card is to be captured, and if so, disables the payment function of the transaction card via activation of a disabling system.

An authenticated data transfer system may include generating, after entry of one or more processors of a transmitting device into a communication field, a link, the link comprising a near field communication data exchange format uniform resource locator including identifier data and user data; transmitting, to a first application comprising instructions for execution on a first device, the link to initiate data transfer; authenticating a user associated with the first device by activating one or more actions based on the link; transmitting one or more requests for confirmation of quantity and recipient data associated with the data transfer; receiving one or more notifications that are based on the one or more requests for confirmation of quantity and recipient data associated with the data transfer; and performing one or more login credentials that are responsive to the one or more notifications so as to complete the data transfer.

A payment terminal may receive a request to process electronic payment information from a chip card in an expedited processing mode. The payment terminal may provide an opt-in request. If a user accepts, the payment terminal may receive a request for payment and request an electronic payment response from the chip card. The payment terminal may receive the electronic payment response from the chip card and store it in memory at the payment terminal. The payment terminal may approve the payment transaction associated with the electronic payment response, allowing the chip card to be removed from the payment terminal. The payment terminal may process additional requests for payment and associate payment-type and time indicators with each electronic payment response. The payment terminal may transmit approval requests to one or more payment servers when the terminal determines they may be transmitted, and, for each request, receive a payment approval response.

PROBLEM TO BE SOLVED: To provide an information service system and the like that can notify useful information using location information to a user terminal that does not use a location-based service.

SOLUTION: In a settlement server 200 in an information service system, an acquirer 242 acquires location information indicating a payment location where a payment was made, for example, when a taxi fare was paid by a payment application executed on a user terminal, from a settlement device that processes settlements in the taxi. A generator 243 generates regional information to be provided by an information service application of the user terminal, based on the acquired location information. Then, the transmitter 220 transmits the generated regional information to the user terminal, for example, in a push notification format.

A multiple-application systematic framework for an IC card comprising a card issuer device 10, a service provider device 20 and a user terminal device 30, in which the three devices are interconnected by a first communications means. The card issuer device 10 comprises a card-issuing module 100 and a service provider management module 101. The service provider device 20 comprises a service module 200. The user terminal device 30 comprises an IC card 300 supplied by a card issuer and a communications device 301 comprising an application control module 3010, the IC card 300 comprises an authentication and security management module 3000 and a multi-application data storage area 3001. The communications device 301 and the IC card 300 communicate through a second communications means. The service provider management module 101 enables the service module 200 to use storage space in the multi-application data storage area 3001 for providing a service to a user via a service token, and the service module 200 communicates with the application control modulo 3010 enable a user and/or at least one service provider to manipulate one or more service tokens in the IC card 300.

Methods and systems are presented for enabling an online service provider to process transaction requests according to a dual control workflow using multiple transaction processing systems that are only configured to process transaction requests according to a single control workflow. A dual control module is implemented between an interface server and the transaction processing systems. The dual control module may intercept transaction requests from the interface server. The dual control module may withhold transaction requests from being sent to any one of the transaction processing systems until a set of criteria is satisfied according to the dual control workflow. The dual control module may obtain approvals and/or denials from designated approvers. Once the set of criteria is satisfied for a transaction request, the dual control module may forward the transaction request to one of the transaction processing systems for processing.

A first request for a transfer of data is transmitted in response to the use of a user device; it is determined that the first request for the transfer of data has been declined; an event is detected that indicates that the transfer of data in response to the use of the user device can be accepted; and a second request for the transfer of data is transmitted in dependence on detecting that the event has occurred.

A device may receive application data associated with transaction applications of client devices and transaction card data associated with transaction cards. The device may receive geographical data identifying a geographical area associated with users of the client devices and the transaction cards. The device may determine, based on the application data, the transaction card data, and the geographical data, location data identifying geographical locations of the users in the geographical area. The device may determine, based on the location data, quantity data identifying quantities of the users located on multiple paths of the geographical area. The device may process the geographical data, the location data, and the quantity data, with a machine learning model, to identify a path with less than a threshold quantity of users in the geographical area. The device may perform one or more actions based on the path.

A transaction indicator monitoring computer-implemented method, medium, and system are disclosed. One computer-implemented method includes obtaining sampling sequences of a transaction indicator of transaction data under multiple sets of transaction dimension values, each set of transaction dimension values corresponding to one sampling sequence, a first sampling sequence including values of the transaction indicator at a predetermined quantity of sampling points under a first set of transaction dimension values, and a value of the transaction indicator at a target sampling point is a first actual value. An estimated value of the transaction indicator at the target sampling point in the first sampling sequence is calculated based on the first sampling sequence and compared with the first actual value, to determine whether the transaction indicator at the target sampling point under the first set of transaction dimension values corresponding to the first sampling sequence is abnormal. An abnormality prompt is given.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating rules to apply to fare transactions when a fare card reader cannot communicate with an authorization server, for generating historical data and a risk score for a fare card that are used by a fare card reader, with the rules, to determine whether to authorize access to a transit service when the fare card reader cannot communicate with the authorization server, and for selectively permitting or denying access to the transit service using the rules and the historical data or the score for a fare card.
