Description
BASIC IDEA:
RFID (radiofrequency identification) technology offers the ability to provide many new services and conveniences in the retail environment. Shoppers can be guided electronically to find desired products that are tagged with RFID chips and whose locations are tracked by RFID readers in the store (e.g., smart shelves or other reader systems). Smart shopping carts with electronic displays, in communication with a retail computer system, can display a map associated with a shopping list downloaded by a shopper to identify a route to obtain the desired items. The smart cart, also equipped with RFID tags, can also verify the purchase of the items as they are placed in the cart and, if desired, communicate with a billing system to automatically bill the shopper for the purchases.
INTRODUCTION TO RFID
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. The technology requires some extent of cooperation of an RFID reader and an RFID tag.
An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

The Advantages of RFID Over Bar Coding
No "line of sight" requirements: Bar code reads can sometimes be limited or problematic due to the need to have a direct "line of sight" between a scanner and a bar code. RFID tags can be read through materials without line of sight.
More automated reading: RFID tags can be read automatically when a tagged product comes past or near a reader, reducing the labor required to scan product and allowing more proactive, real-time tracking.
Improved read rates: RFID tags ultimately offer the promise of higher read rates than bar codes, especially in high-speed operations such as carton sortation.
Greater data capacity: RFID tags can be easily encoded with item details such as lot and batch, weight, etc.
"Write" capabilities: Because RFID tags can be rewritten with new data as supply chain activities are completed, tagged products carry updated information as they move throughout the supply chain.
