Automatic Toll Road Payment System Security Using Radio Frequency Identification (RFID) with the Blowfish method

This paper makes the toll road payment system automatically using Radio Frequency Identification (RFID) using the Blowfish method. RFID will be applied to toll road payment system aims to be able to identify objects quickly, so that will provide time efficiency and will realize a new revolution in payment management. In applying for the payment automatically is necessary accuracy and speed for the introduction of the object. So by using such a system is expected to reduce the congestion that often occurs in front of toll doors and toll road exit. This is usually due to the length of time spent on manual payment transactions at the toll gate, where using a manual payment system can make the toll road service limited efficient and less satisfactory. In addition to the speed of transaction time in the toll door, data security is also required from the device used by the user i.e. electronic card toll or e-toll using RFID tags. E-toll card data theft will harm the user. The blowfish method here is used to secure or conceal user data, so securing user data can prevent manipulation from occurring to duplicate RFID tags.
