So I can buy a “de-laser” machine ,, buy a cashiers check for $10 , de-laser it ,, and imprint my new amount ,, say $100,000.00 and change the recipient at the same time.. cool.
But there is security devices in checks such as watermarks.
The man who designed those watermarks in checks is Frank Abagnale Jr. whose life was made into the movie “Catch Me If You Can”.
