A debit card transaction in Canada consists of:
The retailer keys in an amount.
The card is swiped.
You look at your hand-held display. It says how much. You say "OK" or "Cancel".
You enter your PIN (security number).
You pick which account you are paying from.
The Debit machine connects to the bank, checks that your account has the money and the PIN is correct, then moves the money from your account to the business's account.
...
While someone could engage in fraud, they can't debit you for more than you OK them for without engaging in fraud.
