MANAGEMENT OF DIGITAL RECEIPTS

摘要

Digital receipts for purchases can be managed using a variety of techniques. Digital receipts can be obtained by an application running on a computing device and can be authenticated when not connected to a server, such as when offline. Digital receipts can be efficiently synchronized, such as when connected to a network for other reasons. A last synchronization timestamp can be obtained and sent to a server environment and digital receipts can be received that are new and/or have been updated since the last synchronization timestamp.
