Abstract
This paper presents an innovation in the implementation of RFID in terms of authentication and offline intelligent payment system in public transport, Bus Rapid Transit (BRT), for the academicians. The authentication is conducted using a contactless smart card as an e-ticket as well as an identity card. Contactless smart cards can be obtained through the registration process on the administrator to store user's identity in specific sectors and provide classified authentication key for the card. Passengers will make the payment on a device that has been previously installed on the BRT, called Contactless Payment Terminal (CPT). CPT consists of Raspberry Pi 3 Model B, MFRC522 and LCD Waveshare 3.5. CPT works without requiring server communication when conducting the transaction, but rather accessing the data stored in the contactless card. The optimum range for the CPT can identify the data on the contactless card is at a distance of 1 cm and 2 cm with a percentage of 100%, the percentage decreased by 86.67% at a distance of 3 cm. The fastest delay time is 0.1 s at a distance of 1 cm and the longest is 2.7 s at a distance of 3 cm. The designed system is also equipped with a website operated by an administrator to register a new user, to edit the user's identity, to top up the user's balances, and to check the transaction history.
