Details of the problem:
Hello, there are two types of cards in the consumption setting fixed-rate consumption mode: the first type of card is 5 yuan for breakfast and 7 yuan for Chinese food. The second type card is 10 yuan for breakfast and 20 yuan for Chinese food, can it be realized and how to set it?
Expert answer:
Hello, currently a consumer machine cannot implement this function. However, this function can be realized by using two consumer machines, one set the consumption amount and fixed consumption of one type of card, and choose one type of card when issuing the card. The setting method of the two types of cards is the same for the same type of cards.
