Beware of Credit and Debit Cards
These cards are basically allowing you to use someone else's money that eventually you would have to pay back. If you do not have that money by the time they will start to send you bills and adding on interest if you don not pay them back in time.
These debit cards are linked to your bank account and every time you use it that money from your bank account gets taken away. The good part about debit cards is that it tells you if you have no more money left over in your bank account. With the credit cards you can keep on spending then you would be in debt.
