This system was developed to make a booking bus ticket system in Malaysia easier since the currently used manual system is using manpower and is having some difficulties and quite problematic to handle a lot of customers at once when it comes to holiday celebrations or public holidays. Hence, we developed a system named "BusTicket" to make sure people have a functioning operating system while booking tickets. The system can be used by customers and will display all the details while the system will make sure the input that has been key in is accurate so the system does not have any particular reason to reject or postpone their booking. This system is expected to operate smoothly, accommodating and is a user friendly structure.
