Tag...you're it! Gotcha...now read on to find out about RFID tags....
As we talked about previously, the RFID reader is needed in order to read the individual RFID tags. An RFID tag is placed on each object that needs to be tracked, just as a barcode is placed on items.
However, RFID tags can hold a lot more information than a barcode. RFID tags can track each individual item whereas a barcode is the same on every similar bottle of shampoo. So, with RFID tags you can track down to a specific item (remember, that's the bluebean!)
Once the RFID tag passes by the reader (antennas and portals are key to this process too...we'll cover those soon!), the tag's data is sent to the reader. Each tag's unique ID is it's individual "finger print" and this is what gives RFID an edge over barcodes.
Make sense? Good...now stay tuned for more on the role of the RFID portal and the RFID antenna.
