Jim idk if you're still living in 1994 or what but today there are these little things people carry in their pockets that allow them to take a picture of anything they'd like in literally 2 seconds flat. This means they wouldn't have to memorize anything. Really amazing technology and literally everyone has them!If you can memorize my credit card info in the amount of time it takes to pass my card....hats off. I won't even report it stolen right away.
