Desarrollo de un prototipo de sistema de pago automático de compras mediante una aplicación móvil para una caja rápida con tecnología RFID

Abstract

This project develops an automatic payment prototype system for express checkout counters at supermarkets. This prototype uses RFID technology to read the products and an Android application for making the payment. It also includes the development of an ASP.NET web application for supermarket management. The system consists of four essential components: the database, the express checkout counter, the Android application and the web application. First, the database stores the information of the supermarket (e.g. the products). Second, the web application allows the management of customer accounts, product management and the generation of sales reports. Third, the checkout counter is composed of a computer connected to an RFID reader to scan the products to be acquired. Finally, the Android mobile application works as an electronic wallet allowing the customers to view the details of their purchases. It should be noted that functionality tests and average purchase time estimates show the usefulness of this prototype as an alternative and complementary system to the traditional barcode scanning model.
