Cloud-based information exchange using identifiers such as QR codes

摘要

Document capture and tracking is simplified using coded information that may be printed on the document. In one embodiment, the coded information is scanned. As a result, the information of the document or a pointer thereto is retrieved or stored from a server (i.e., from the cloud). Preferably, the information of the document is in XML format such that one or more interested programs may process the information intelligently.
