Abstract
This article discusses how technological innovation develops to support conventional merchants by implementing RFID for a fast and easy payment solution. This payment uses a contactless smart card as a medium for electronic money or e-Money. This e-Money card can be obtained through a cashier available at merchants and e-Money balance can also be topped up by registering the card first. This cashless machine uses Arduino UNO as a microprocessor, MFRC522, Micro SD Module and 16x02 LCD Display. This cashless machine does not require internet to access the database and can also be used immediately without problems. This cashless machine can work within a range of 3cm for e-Money card detection with the fastest response time of 0.1s and takes a long time to process a balance of 1.4s. This machine is equipped with a menu variant selection at merchants using a serial monitor display integrated on the Arduino UNO.
