Prototipo de un sistema que permita utolizar el teléfono celular para realizar compras en establecimiento comerciales como alternativa a la tarjeta bancaria

摘要

This thesis project describes the development of a prototype system that allows buying in commercial establishments using the cell phone as an alternative to the debit card. The prototype compounds of three main elements: one mobile application installed in the client’s cell phone; another mobile application installed in the seller’s cell phone; and one server application that processes the orders sent by the users of the system. The first mobile application allows the user to buy in any commercial establishment that provides the service, and to check the purchase history. The second mobile application allows the commercial establishment to check for and verify received payments, and to check the sales history. Finally, the server manages petitions, confirmations and funds transfer related to purchases and sells performed by the clients and the commercial establishments respectively. The communication between the server and the mobile applications is made by SMS text messages.
