RFID vs RF

Dear All,

I am very new to RFID Technology. My company is thinking to implement RFID .

As i am novoice to RFID , Please help me to understand few concepts.

1. When we are talking about the business process , lets consider we have RF guns in our business line - now when we are implementing the RFID what all changes?

2. Do we need to change the complete business process to implement the RFID against RF guns?

Please help me to understand.

Thanks,

lakshmi
