SWEP Protocol and S-Wallet System - Mobile Payments using Near Field Communications

摘要

This paper presents a system for mobile payments denominated S-Wallet using the technology of Near Field Communications (NFC) currently present in several smartphone devices. For this system, a protocol called SWEP was developed with encryption algorithms (RSA and 3DES). An application for the Android platform has been also developed in order to carry out performance tests and security. The protocol presented in this study proved to be adaptable to different situations of mobile payment. The S-Wallet system showed satisfactory results compared to other systems in the literature. The project carried out in this research can be used to maximize security, usability and efficiency of mobile payments.
