Abstract :
This paper reports the Implementation of a
Radio Frequency Identification (RFID)-based
multiproduct vending machine. It is designed to
automatically dispense drinks such as coke, malt and
yoghurt using RFID prepaid method system. After a
careful analysis of the existing system, noting its
shortcomings, a new system was designed and developed
such that the shortcomings of the old system were
carefully overcome. The system was designed using
Microcontroller (Ardiuno Mega board), RFID tag/card
reader, servo, Liquid Crystal Display (LCD) and other
electronic devices. Prototyping methodology was adopted
and the machine parts (hardware and software) were
designed in modules. These modules were then
separately tested and found to be functioning as desired.
They were then integrated to form the finished product.
A C-language based software that is able to drive a
multiproduct vending machine was designed and
implemented in this work and it made the hardware
components to function in a well-co-ordinated manner.
The customer can buy product using RFID card by
swiping the card across the RFID card reader, then the
embedded system reduces the amount from the card,
shows balance on the LCD display and the product
which is stacked in the machine plunges out of each
funnel inside the machine (this is controlled by a servo
attached to the microcontroller) and accessed via the
dispensing unit outlet. The vending machine developed
in this thesis uses a PC as a guide to connect to the
machine especially for generating recharge codes. The
RFID based multiproduct vending machine was
compared with the cash-based alternative and found to
outperform it in terms of flexibility, efficiency and
security and has a better way of managing the financial
return to the business due to the prepaid method of
recharging the RFID card
Keywords :
LCD, Microcontroller, multiproduct vending machine, etc.
