Today, we can choose using credit card or using cash. What do you think about credit card? Are you afraid of using it too much? I choose using credit card which is more convenient than using cash. There are three reasons.

First, we can buy things without cash. We just need to sigh or press PIN code to shop. Besides, we can shop all over the world because we do not need to have cash. It means we do not have to exchange money everywhere we go. And if we do not have money at that time, we can buy what we want. Of course we have to return later.

Secondly, we can enjoy shopping on Internet. Recently, Internet shopping services, Amazon, Rakuten, Yahoo, are satisfactory. We can buy everything. If I buy something, those services can delivery me during the day at the earliest. I think it is very useful. To use those services, we need credit card.

Finally, we can earn some points through using credit card, for example, miles, shopping points and so on. For instance, we can exchange miles for airline ticket. We have to be wise, if so we can earn a lot of points and gets benefits.
