Solar operated water ATM

This is an automatic liquid vending machine based on radio-frequency identification (RFID) system. A fixed amount of liquid can be dispensed by swiping an RFID tag across the RFID reader. An alphanumeric LCD is used to display the operation and instructions for users to follow while dispensing the liquid. This machine could be implemented in organisations like hospitals and colleges (medical, engineering, etc) to provide 24-hour service to customers with no humans involved.
