Both RFID tags and barcodes are used to tag products, but RFID has many advantages.
An RFID tag can be read at a distance. That helps with inventorying stock, and also helps to catch shoplifters.
Retailers have a problem with shoplifters putting an expensive item in a cheap item's box; because the RFID tag would be on the product itself it wouldn't matter what box it was in.
