In Bangladesh almost 70% people use railway system as common transport. Among them majority of the train commuters have to endure undesirable difficulties in collecting ticket as the existing railway ticketing system is severely engulfed by corruption. Up to now Bangladesh railway system has been using a manual ticket issuing system. This leads to long queue and wastage of time and corruption. So the train commuters have to experience difficulties when purchasing their tickets. An effective and secured solution to this problem is to automate the system. In most of the developed countries of the world there are automated ticketing systems based on smart card. Now-a-days this automation in ticketing system is very much obvious around the developing countries of the world. Our proposed system for Bangladesh Railway is low cost automated ticketing system using RFID card. If RFID cards are provided to train commuters as a step of Government, this will be easily accessible to passengers. Commuters have to be registered when collecting card. During registration passengers must provide their information regarding to address, name, age, profession. Then railway will give a unique password to them. The information of user including password, discount facilities and others are stored in the system. At the time of purchasing tickets when the card is touch to the ticking machine for a few millimeters from the reader, user id no and corresponding password is asked for matching to the system. If this information is verified, then the user can purchase ticket for desired destination. The screen of the machine on which user can feed all the information regarding date, time, arrival and departure stations will be appeared if the person is verified. On this display passenger can be provided with extra facilities to observe all the information about stations and trains. Touch screen display will be more convenient to user. When all the information will be given, sufficient amount will be deducted from the card. This information is stored in system. RFID systems are widely used for identification and security.
