Do I even need credit cards?
If you are in the U.S., without credit cards, you probably don't have a credit history. Without a credit history, you won't be able to get a loan/mortgage, and even if you do, you'll get it on very unfavorable terms. Depending on where you live you might even have great difficulty renting an apartment. So, the most important reason to have credit cards is to have a good credit score. People have already listed other advantages of having credit cards, but another thing that wasn't mentioned is fraud protection. Credit cards are better protected against fraud than debit cards. You probably shouldn't use debit cards online unless you must. Also, without a credit card or credit history, some simple and important liberties like renting a car while you are travelling might be denied to you. So, in conclusion, it's bizarre, but in modern America you need credit cards, and you need them bad.
