I just found out that my 12-year-old son has my credit card number memorized. I have only occasionally let him use it and it has been at least a month since I last let him use it. He says he never tried to memorize it, he just remembers it. When I let him make an online purchase today he was able to type the number correctly without looking at the card and he also remembers the 3-digit number on the back. He only needs to look at my card to double check that his "dyslexia" which he has not been diagnosed with didn't cause him to accidentally transpose any numbers.
He always memorized lines faster than most kids but he never really talked about his ability to memorize numbers. He says he has always been able to do this.
I don't have my credit card number memorized. My husband doesn't have it memorized either and we don't have "learning disabilities."
