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: A cashless transaction processing method is disclosed. The method comprises: receiving, in an issuer server, a transaction token request from a customer device, the transaction token request comprising an indication of a payment card account associated with a customer; providing a token to the customer device in response to the transaction token request; storing an indication of the token on the issuer server; receiving, from an acquirer server, a transaction authorization request, the transaction authorization request comprising a token; authenticating the token received in the transaction authorization request against the stored token; and initiating a transaction for the transaction amount from the payment card account associated with the customer.
