What are two differences between an RFID and a UPC system?

UPC is a global database of product information formatted in a bar code system. The codes are placed on products or containers and are scanned with a laser and read by a computer to log and track information. RFID is a radio-frequency technology designed to help in tracking and data collection.

Which is better barcode or RFID?
