Can you scan real money?

Excuse me, I've been hearing a lot about the advancements in technology and how it's changing the way we handle money. I'm curious, is it possible to scan real money using technology? I'm thinking specifically about converting physical currency into digital form or perhaps using some sort of scanning technology to verify the authenticity of bills. Could you elaborate on the current capabilities and limitations of scanning real money, and if there are any security concerns or benefits associated with this process?
