① Credit card has no function of value scale ② Credit card cannot be used as a means of circulation ③ Credit card has no means of storage ④ Credit card will not become the world currency

A.12B.23C.234D.1234P > Answer: D

Credit card is only the carrier of electronic money, not the electronic money itself. There are many carriers of electronic money, and now there are virtual carriers, such as Alipay, Tenpay and online banking.

Although the money in a credit card is just numbers, it is really money, which is called "electronic money". Except that it has no materialization, its function is similar to that of paper money, and it has the function of means of payment, but paper money also has the function of circulation, and some paper money also has the function of world currency (such as US dollars and euros), but electronic money does not. Storage means and value scale are only available in currency, but electronic money and paper money are not available.

the so-called means of circulation refers to the function of money as a medium of commodity exchange. When we use a credit card to spend money, the electronic money in it also acts as a medium of commodity exchange, so the electronic money has the function of circulation means, but the credit card strictly does not have this function.
