A system and computer-implemented method for analyzing chip card transactions to identify defective chip cards and/or defective chip readers in need of replacement. Constraints are established to define a subset of card transactions. From a full set of card transactions the subset is identified consisting of each card transaction falling within the constraints and occurring at a merchant having a chip reader. From this subset the unique chip cards are identified, and for each unique chip card a percentage of fallback transactions is calculated. The percentage of fallback transactions is compared to a maximum value, and if the percentage of fallback transactions exceeds the maximum value, the chip card is identified as defective. Each defective chip card is reported to the card issuer, along with at least a recommendation to replace the defective chip card. A similar process may be used to identify defective chip readers of particular merchants.

A computing node comprises a processor and a transaction cache. The transaction cache comprises transaction data records for a plurality of account numbers. Each transaction data record comprises a plurality of transaction data elements for a transaction including the account number for that transaction. The computing node is adapted to receive an authorization request for a transaction pending authorization from a transaction network, use the transaction data records in the transaction cache to calculate function values for one or more predetermined functions for the account number associated with the transaction pending authorization, wherein the function values are determined from the transaction data elements of the transaction data records for that account number, and provide the calculated function values to the transaction network. If the transaction pending authorization is authorized, the computing node adds a transaction data record for that transaction to the transaction cache.

The present disclosure provides a server for processing a transaction using a plurality of devices. The server comprises at least one processor; and at least one memory including computer program code. The at least one memory and the computer program code configured to, with the at least one processor, cause the server at least to receive, from a second device, a request to continue with the transaction, the transaction being initiated and postponed by a first device. The server is then configured to determine whether the second device is associated with a user account that is associated with the first device; and transmit, to the second device, details relating to the postponed transaction based on the determination of whether the second device is associated with the user account to enable the second device to further process the transaction.

A system and method for validating user address information is disclosed herein. A computing system periodically polls a client device associated with a user to identify a current location of the user. The computing system records the current location of the user after polling and a time associated with the polling. The computing system receives one or more transactions from one or more third party vendors. The computing system identifies, based on the one or more transactions, a location and a time associated with each transaction in the one or more transactions. The computing system defines a geographic area. The computing system determines that a current primary address on file for the user is outside of the geographic area. The computing system prompts, based on the determining, the user to update the current primary address.

The present application discloses methods and devices for providing risk information. A risk factor corresponding to a risk control decision result of a service that matches service data for a corresponding risk factor is determined. The risk factors are associated with risk control rules and a risk control model identifying relationships between risk factors and risk control decision results. A risk information set corresponding to the risk factor is determined that includes levels of risk information having different refinement degrees and including information explaining a cause of the risk control decision result. The levels of risk information are determined from the levels of risk information based on a risk information requirement level of a service owner of the service. The levels of risk information have refinement degrees matching the risk information requirement level of the service owner. The levels of risk information are provided to the service owner.

A virtual card opening method and system, a payment system, and a card issuing system are disclosed. The method comprises: receiving, through an online traffic entrance associated with a payment system, a virtual card opening request from a user, the virtual card opening request comprising user information and type identifier information of a virtual card; searching, by the payment system, for a rule for acting as an agent to open a card and a card opening condition corresponding to the type identifier information from the payment system, the rule for acting as an agent to open a card and the card opening condition being obtained in advance by the payment system from a card issuing system; and generating, by the payment system, a target virtual card according to the user information and the rule for acting as an agent.

A processor may detect a transaction made using a point of sale system. The processor may determine that the transaction indicates a smart device is not in use. The processor may send a command causing the smart device to operate in an away mode.

Various embodiments are generally directed to method and devices to receive biometric data and transaction data relating to a transaction, apply a model to the biometric data and the transaction data to determine an emotional state of the user during the transaction, and determine an action associated for the transaction based on the emotional state of the user during the performance of the transaction. Embodiments further include causing performance of the action.

The present invention relates to virtual code-based control system, method and program, a control device and a control signal generating means. A control method on the basis of a control signal comprising a virtual code according to an embodiment of the present invention comprises: a control signal receiving step for a control module receiving, from a control signal generating means, a control signal generated by means of combining a plurality of specific codes in accordance with a particular rule; a step for the control module extracting the plurality of specific codes comprised in the virtual code; and a command searching step for the control module searching for a storage location comprising a particular command on the basis of the plurality of specific codes.

A method and a program for outputting a virtual code generated from a payment card, and a payment card for generating a virtual code are provided. The method for outputting the virtual code generated from the payment card includes receiving, by a virtual code output application, a virtual code from a payment card after connecting the payment card with a mobile terminal through short-range wireless communication, and outputting, by the virtual code output application, the virtual code on the screen.
