Produce chip card for transportation business

I am a Cameroonian looking for someone who can develop an application that can be embedded in a chip card for a transportation business in Cameroon. This would require a component that can be installed in cars as well as bikes. The component would be used to scan cards each times someone boards the car or mounts the bike. Once scanned, the fare would be deducted from the prepaid card until the credit in the card is exhausted. The system should allow the use of credit in the card to be monitored through records in client accounts using a computer (laptop or desktop) with details on trips or rides that resulted in the deduction of credit. An app to top up credit on would also need to accompany the system. Please, send proposals including cost as soon as possible. Regards Emmanuel
