Facing all these problems and at a time that digital is booming, we develop a solution of automatic payment without contact via NFC technology. Concretely, we make available to all students and users an NFC card connected with a rechargeable mobile application via the means of local money transfers (mobile money). And to pay our users spend their cards 10 cm from our smart readers without any information. This solution will help save time, contribute to the promotion of clean and Eco-responsible universities.
