Abstract:
A system for performing a restore transaction, in response to interruption of a value increase transaction involving a particular electronic payment card, after an authorization for the transaction has been given to the card for the value increase transaction, wherein the particular card stores a balance, the system comprising:(A) an authentication device which determines authenticity of the card and, in response thereto, generates an authentication of the card;(B) an authorization device which checks authenticity of the card and generates an authorization to increase the balance of the card;(C) a storage device which stores a plurality of restore records, each one of the records having identification data, which identifies a corresponding one of a plurality of electronic payment cards, and authorization data which authorizes an increase of a balance stored in the corresponding one card; and(D) a control device coupled to the authentication device, the authorization device, and the storage device, the control device being capable of communicating with the card;(E) wherein the control device performs the value increase transaction which, prior to the interruption, comprises the operations of:(E1) receiving the payment card authentication for the particular card so as to define a received payment card authentication;(E2) receiving the balance increase authorization for the particular card so as to define a received balance increase authorization;(E3) generating a balance increase message in response to the received payment card authentication and the received balance increase authorization; and(E4) sending the balance increase message, including the received balance increase authorization, to the storage device such that the received balance increase authorization can be stored, as authorization data, in an associated one of the restore records corresponding to the particular card; and(F) wherein the control device performs the restore transaction which, after the interruption of the value increase transaction occurs, comprises the operations of:(F1) determining that the value increase transaction was interrupted; and(F2) ascertaining a last value increase transaction message sent prior to the interruption and resuming the value increase transaction at its point of the interruption, wherein the resuming operation further checks authenticity of the particular card and performs the last value increase transaction, after the interruption, in response to the authorization data stored in said associated one restore record, wherein the performing operation:(F2a) retrieves the authorization data, for the particular card, stored in the associated one restore record, so as to define a retrieved balance increase authorization; and(F2b) re-sends the balance increase message to the particular card in response to the retrieved balance increase authorization.
