This paper proposes a very novel approach to implement the automatic toll tax collection system on the toll plazas using radio frequency identification (RFID) and global system for mobile (GSM). Nowadays, the cities and highways are bursting with traffic, and very often long queues of vehicles can be seen at various toll plazas so that they can pay the toll and then able to use the road or highway. So a system is proposed wherein the toll tax could be paid via cashless transactions and people wouldn’t have to wait for a long time for the cash payment of the toll tax. This would save people’s money and time simultaneously. It would also eliminate errors in cash transactions and further ease the job of the toll plaza companies. It would definitely bring down any of the corruptions occurring at the toll plazas. Finally, it would make the existing toll tax collection more efficient and ease our lives a bit more. © Springer Nature Singapore Pte Ltd 2019.
