Simple - a debit card cannot authorize if you have less money in the
account than you are asking for.. It is "direct bank transfer". It
simply will not authorize and turn on the pump.


Yes and no. The problem in low balance situations where the debit card
is tied to your checking account is that you can get authorization for
it one minute and the next minute a check arrives that you didn't take
into account. The hold from the card means you don't have enough money
to pay the check and it bounces.

Anyone with a debit card on a chequing account who doesn't have
overdraft protection is setting themselves up for a pile of grief.
