It features a hardware device built using an Arduino UNO with Ethernet and RFID components. We have developed a simple protocol over TCP/IP that the device uses to communicate. The receipt data is processed through JSON services provided by an application built on Ruby on Rails. To showcase possible applications we have developed an Android app capable of receiving the information through NFC. We have also shown that non-RFID enabled devices, as the iPhone, are able to receive the same information.
