Project Description
The project is about to create a system for settlement by the Popcard in commercial vending machines.
The author is a vending machine in the hallway of their building and was selling drinks to your neighbors. Think of how selling drinks without cash, started this project.
The author built using Arduino, Adafruit ethernet shield, WIZ811MJ, LCD, RFID reader.
The basic operation of the system is like this: A user scans their card, which is read via the RFID reader. The ID is sent to a piece of software running on one of my servers, which compares it to a database and retrieves the user name and their current credit amount. This is then displayed. If the vending machine is ready to accept money, pressing a "buy" button subtracts $1 from the account and places it in the machine. The user can then use that money to make a beverage purchase.
