The discovery services offered on the EPCglobal Network are used to find RFID tags marked with EPC codes
. These services enable trading partners to find all parties that use tagged products. One of these services is the EPC InformationService (EPCIS). It is the standard
for the company databases in which file information about the products marked with the EPC code is contained. This information includes the manufacturer, product class, serial number, and dimensions and weight. Other EPC discovery services can be used to retrieve various information about the companies involved in the supply chain and the current status of the deployment. Authorized network participants can access this information.
