What Is the Most Important Comparison Between RFID and Bar Codes?

That is an interesting question. I guess I would have to say the biggest difference is that RFID does not require line of sight, as bar codes do. This allows you to read all tags on items within a box, for example, to protect a data carrier by embedding it in a plastic container, and to automate data collection. With an RFID system, a person could walk past a reader portal carrying five or six clothing items on hangers, and the tags could be read automatically.
