This project is about new life and the media. In today's increasingly convenient, people will certainly take the mobile phone out. However, there are still some inconvenient things to do, like trying to buy a snack or drink on a vending machine and finding that there is no cash on it. If you can pay by mobile phone at this time, then this problem is very simple.So I designed an app for vending machines with detailed product information on the app. Use your mobile phone to pay for it easily.
