Worked on an RFID implementation project in Malaysia for Touch ‘N Go. The project aimed at streamlining toll payments and parking payments using RFID technology, enhancing the overall efficiency and user experience in transportation. RFID tags are attached to vehicles and registered under individual accounts. When a vehicle entered a toll or parking area, money was automatically deducted from the linked Touch ‘N Go (TNG) e-wallet. The RFID tagging process occurred at fitment centers operated by service providers across Malaysia. Touch ‘N Go has around 30+ million active cards, with individuals often holding multiple cards. Additionally, the TNG e-wallet app allowed users to add, and reload their physical TNG cards, further simplifying the user experience.
