How can a Debit Card get me out of debt?

Switching your credit card for a debit card is one of the best things you can do financially.

It means that whenever you use your debit card, you're spending your own money - not borrowing from your financial institution for your purchase.  It helps you to not spend beyond your means as a debit card will not work if there are not sufficient funds in the linked account.  Of course, using a debit card is not  a silver bullet for getting out of debt - you may still have an existing credit card to pay off or perhaps have other forms of credit such as a car loan, personal loan or mortgage.  However with credit cards typically providing the most expensive form of finance, switching to a debit card is a big step and will save you money immediately.  Not to mention it's symbolic and a sign of someone who is in control of their finances.
