关于credit card不知道credit card到底有什么好处，只是听说在外面吃饭付账的时候比较方便。我也想办一张，不过不知道哪家银行的比较好。另外，这样的服务银行一定要赚钱的吧，不过有些credit card第一年都不用付钱，他赚什么啊？不懂，那位可以指点一二？多谢多谢。
credit card has surcharge.
they earn from surcharge (that's why some shops refuse to accept credit cards, or require a minimum amount for it) on the shops.
they earn from interest impose on you if not paid back on time.
...
Don't worry for credit card issuers (these need not be banks). They have plenty of ways to make money out of you (or your actions, if that matters).
