Abstract

An application identifier (AID) for an application installed on a smart card comprises a registered application provider identifier (RID). The AID may be processed by determining the RID for an application from the AID of the application, generating an identifier for a network resource from the RID, transmitting a request to the network resource using the identifier, and receiving a response to the request. The response comprises material for use in handling the application on the smart card.
