For one thing I'm not giving someone I don't know my bank account number for a wire transfer. What's so hard about going to the post office to get a money order?
And yet we’ll willingly hand a check or mail one with our account number to a stranger. I know very few people actually still use checks but they’re still more secure than debit cards. Without an ID and PIN number there not much way to get money out of your account with just an account number.
