For all the security in online banking, you sometimes can’t find your bank account number. I mean the full one. Lets face it, you hardly have to use it anymore. ATM cards, your bank’s site’s cookie and your social security number have all replaced our need to memorize our bank account number. My dad had his bank account number memorized for thiry years all I have to remember is my password. But, when you’re asked for it, the full account number, where do you get it from? Citibank which makes me feel very smart for choosing them, provide the solution. Very simple, you can choose to have you account number displayed in a masked format (xxxxxxxxxxxxxxx-111) or display it fully. I love them for that. Now, if they could only apply some of their online logic to their billboard campaign.
