I just can't figure it out, How does a change machine figure out if you're putting $1 or $5 or $20?

How does it know these things?

They used to have little strips in the bills that were read by the scanners.

You know, I haven't looked that closely at these newer bills that have come out. Guess I'll have to check on that.

a computer inside the change machine optically scans for programmed markers that are unique to each bill.
