This project falls within the scope of the configuration and programming of a Point of Sale (PoS) for the payment by using the contactless technology RFID and NFC. The main objective is to implement the PoS in ESADE to perform the payment of menus or any other amount using ESADE's corporate cards or Android mobile devices. To achieve this goal we chose a PoS that meets the requirements specified by ESADE in which we have designed and developed an application to carry out the payments. We used the RFID technology to identify ESADE's corporate cards and also developed an Android application that, by emulating NFC tags, allows to identify clients who use Android mobile devices. To connect to the database we used the SOA web services that, consuming this services through the application, will perform the actions needed to record each payment in the database. Finally, we checked the correct operation of our project by performing different payment transactions.
