Which type of card do you prefer? Credit or Debit? Personally, I prefer debit cards. I like to spend what I have rather than go into debt, and acquiring credit card debt in particular is a really bad idea as the interest rates are very high. They also have a bunch of fees if you make your payments late. On the other hand, you do need a credit card for some things like renting a car, where they will often not accept debit cards as "collateral".
