EPCglobal 2005a
A particular tag population is selected with the “Select” command before the inventory process is initiated with the “query” command. Only tags matching the mask of the “Select” command, reply with a random number (RN16) and with their unique ID (EPC).

processing services with frequent changes to the reader configuration.

7. Figure 10.4 Filtering and aggregation of RFID data
Filtering and aggregation of RFID data: data of two dock door readers are combined,
duplicate EPCs are eliminated, EPC is filtered out, and quantities of product categories are
calculated. Eliminated ‘reads’ are shown in grey.
