Abstract
This thesis discussed the methods to read the balance of Touch ‘N Go (TnG) card that currently available and analyse its efficiency and reliability for TnG users. This project intended to resolve the user’s unexpected insufficient TnG card balance by providing a portable smart card reader as an alternative method for TnG users to check TnG card balance conveniently. The development of the portable smart card prototype involves manipulation of Radio Frequency Identification (RFID) system programming in Arduino IDE with MFRC522 RFID module whereby the EEPROM (Electrically Erasable Programmable Read-Only Memory) organization of contactless smart card is written with ambiguous values to be read by the prototype and interpreted as digital money with Malaysian currency. The energy storage system is developed based on utilization of typical application schematic of TP4056 lithiumbased battery charger integrated circuit (IC) alongside FS312F-G battery protection IC. The battery voltage is then converted into a higher direct current (DC) voltage level by MT3608 DC-DC boost converter IC to fulfil Arduino Nano input voltage requirements. All hardware components are integrated on a printed circuit board where its layout design was made using free online software called EasyEDA. At the end of this project, the system was able to read and display the information stored in the smart card successfully. Meanwhile, battery charger had successfully charged a single cell lithium-polymer battery with capacity of 1500mAh up to 4.205V for 190 minutes.
