So, sometime last year, me, my wife and her best friend were riding together somewhere. Even though she's usually the one with money, I was giving her my ATM card to pull out some cash. As I dictated the PIN, her face screwed up into a look of confusion and disbelief.
"What's with all those numbers?"
"Yeah. My PIN is 6 digits."
"What? What kind of PIN is that? 6 digits! You need to change that. That's crazy."
"I will." (I didn't)
The point is, Bank of America is SO large now and they issue out so many cards, that there just aren't enough 4-digit numbers to give their customers a certain sense of security.
They're that large.
Know What I'm Sayin'??
