4. Tagged MRFID reader for automatic identification and navigation.
In the optimal case the MRFID reader is equipped with a device identification tag, which is identified from the master-slave reader system automatically. For example, if a mobile reader with identification tag enters a shopping section, it will be detected from the section (master or slave) readers (Step (9)). This feature allows additional services such as localization or navigation of user of MRFID reader in the smart spaces (chapter 3). The steps 10–12 are similar to the steps 5, 7 and 8 of previous method.
In all of these methods the MRFID reader can query additional information from the smart spaces local, external object server or any other information servers (steps (13) to (16) in Figure 2).
