I actually meant a message popping up on the ATM screen, sort of like a vacation-away responder but for people with bad spending habits.
The functionality you're talking about is obviously much more useful :) I'll have to check and see if my bank has this function, as I probably would not have set it when I opened my account and have yet to receive anything like it. My girlfriend's bank sends her a message when her account is under a certain amount and flat out denies withdrawals over that same amount (i.e. notifies when under $500, can't withdraw more than $500/mo regardless).
