About punching in the canteen.

What makes you say is complicated, but it's actually very simple.

1. The corresponding amount of advance deposit. If you stay for 3 meals, save the amount you should enjoy, 8 yuan per day, 30*8=240, and then deduct the subsidy (office worker 88 yuan). In fact, the person who checked in should pay 152 yuan, but 240 yuan was deposited in the card.

2. Consumers will spend at a fixed time, and the corresponding amount will be deducted every time they swipe their cards. 2 yuan for breakfast, 4 yuan for Chinese food and 2 yuan for dinner, all at once.

You can solve your problem.

If you want to be more clear, you can adopt another scheme.

Buying another machine requires people from different departments to swipe the cards of different machines. Independent credit cards are also acceptable.

Or you can spray different colors on the cards.
