If you are looking to catch up on the concept of RFID (Radio Frequency IDentification ), there is a fairly straight forward rfid training video at RFIDent.org.

In general if you are not sure why you should understand this technology consider that barcodes could be replaced and will be replaced in phases in many retail stores and warehouses across the country.  Wal-Mart, Home Depot, Lowe’s and many other retailers already have plans in place to convert from barcodes to RFID.

Below is a picture of a RFID chip.

These little wafer sized chips can be taped inside a book, inside a package, even sewn into your clothing.  My local library already uses RFID to scan and checkout books.
