Figure 10.2 “Select” command defined in the EPCglobal UHF Class 1 Generation 2 Protocol 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).

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 11.49.40 is filtered out, and quantities of product categories are calculated. Eliminated ‘reads’ are shown in grey.
