Yes, I was indeed mistaken. Pretending to use someone else’s credit card is a crime of credit card fraud.

Then this is an implicated crime. The means is to defraud credit cards, and the purpose is to fraudulently use other people's credit cards. The principle of punishment for implicated offenders is to punish them first, that is, to choose a serious crime and punish them.

But this is definitely not a matter of competition and cooperation, it is clearly two behaviors.

Your supplement has no idea what you are talking about. I don't understand your expression. It's not like you said that there is no provision for multiple crimes to be punished at the same time. Whether multiple crimes should be punished together depends on your own analysis. What the criminal law specifically explains is generally the case where there are originally several crimes, but only one crime is punished. You cannot think that if there is no provision, all crimes will be punished together.
