You dont get my point, it is not about bouncing the check. Im talking about the history of technology changes, and how society has adapted the changes. During the whole time 20th century, government banned the electronic transfer of checks. They had law that checks are required to physically transport them. If you watch the movie, "Catch me if you can" That con artist knew how the paper check were transferred, and made it go around the world, took two weeks for banks to realize that the check is fake. Frank Abagnale himself advised and encourage the concept of 21 century checking system. Uncle sam was opposed thinking that electronics aren't that reliable and not dependable. Now they have changed their mind and law. See? They have changed the minds of technology and they will.
Same with cell phone, I could collect more examples how technology has changed, and how we society have adapted.
