What is RFID Tag ?

RFID (Radio-frequency identification ) is a technology that uses bar codes to track items in a store.

Traditionally  stores uses UPC (Universal Product Code) to identify a certain product, where shoppers stand in line to have the products scanned. If RFID is used, Shoppers no longer required to stand in the line, Instead, RFID tags would communicate with an electronic reader to a large network that will detect all the item in the cart almost instantly, so that the bill is registered and paid automatically from your bank account.

RFID tags will help companies to optimize business processes and reduce operational costs.

Soon, RFID could replace UPC.
