Abstract: A server and method for sending a transaction receipt via a push notification is provided. 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 an issuer server, an approval message approving the user-initiated transaction request and transaction receipt details indicating a completion of the user-initiated transaction request, the user-initiated transaction request having corresponding transaction request details including a unique device identifier identifying a payment device that has been used to initiate the user-initiated transaction request; encrypt the transaction receipt details to provide encrypted transaction receipt details; and push, to the payment device identified by the unique device identifier, the encrypted transaction receipt details via a push notification channel.

Abstract: The invention provides methods, systems and computer programs for dual layer identity based access control implemented within systems that implement a micro-service architecture. The invention involves (i) receiving at a first resource server (a) a request for a first processor implemented service, (b) a primary access token generated by the primary identity authentication server, and (c) validation information corresponding to the primary access token that is transmitted by the primary identity authentication server, (iv) responsive confirming validity of the primary access token, transmitting to a secondary identity authentication server, a request for generation of a secondary access token, (v) receiving the secondary access token at the first resource server, and (vi) transmitting to a second resource server within the server system, a request for a second processor implemented service implemented by said second resource server.

Abstract: According to an embodiment, there is provided a method for authorizing use of an application on a device. The method includes: identifying a plurality of device identifiers of the device; determining authorization information based on predetermined one or more of the plurality of device identifiers; and determining authorization for use of the application on the device in response to the authorization information.

Abstract: A computer-implemented method and computer system are proposed for assisting a consumer associated with a plurality of payment cards. When the consumer wishes to make a payment transaction, a computer system with access to information about the payment cards and access to at least one consequence database storing information relating to consequences of the making payment using the payment cards, determines consequences of making the payment using each of a plurality of the payment cards. According to the determined consequences, the computer system makes an automatic selection of one of the payment cards to use for the purchase. The computer system's selection may be presented to the consumer as a proposal. Upon the consumer accepting the proposal, the payment transaction is performed using the selected payment card.
