2. According to the author, what is the disadvantage of using credit cards?
(A) Your credit cards may be lost or stolen easily.
(B) Credit cards may not be used at some stores.
(C) You may use credit cards too much and spend more than what you have.
(D) Your personal information will be obtained by someone else.

One more thing worth attention is to be a careful user of your credit cards. It is a lot easier – and sometimes safer – to pay with a credit card than to carry around all that cash in your pocket or purse. However, it is also easy to get into trouble with credit cards if you regard and use them as a substitute for money you don’t have or haven’t earned yet. If you charge so much that you can’t keep up with your monthly bills, interest charges will quickly add up. Going into credit card debts is definitely a sure sign of low financial IQ.

值得一提的另一件事是謹慎使用信用卡。用信用卡付款比隨身攜帶口袋或錢包中的所有現金容易得多，有時甚至更安全。但是，如果您考慮並使用信用卡代替沒有或尚未賺到的錢，也很容易遇到麻煩。如果您的費用太多，以致無法跟上每月的賬單，利息費用將迅速增加。信用卡債務肯定是財務智商低的肯定跡象。
