RFID is much more than the next generation of bar codes. It creates a variety of interfaces that can connect computers directly to individual physical items, and even to people.
For instance, all Gillette Mach 3 razor blades would have the same bar code. However, with RFID tags, each packet of these blades would have its own unique identifier that can be transmitted to suitably located readers for monitoring(Srivastava, 2007).
Electronic Product Code (EPC) is the dominant standard for the data contained RFID tags for item-level tracking.
EPC can hold more data than a bar code. EPC becomes a mini database embedded in the item (Srivastava, 2007).
RFID allows data capture without the need for a line of sight, making it more advanced than the bar-code. It allows for easier access with no required physical manipulation of items (Srivastava, 2007).
