In this example, the EPC (in Pure Identity EPC URI form) would be a primarykey of a database that tracks the accumulated exposure for each physical object; eachentry/exit event pair for a given object would be used to update the accumulated exposuredatabase.This example illustrates how the EPC is a single, universal identifier for any physicalobject. The items being tracked here include all kinds of things: trade items, reusabletransports, fixed assets, service relations, documents, among others that might occur. Byusing the EPC, the application can use a single identifier to refer to any physical object,and it is not necessary to make a special case for each category of thing.Copyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
