This is the 5th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. In this tutorial we will be using a Radio-Frequency Identification (RFID) reader/writer to capture information from an RFID tag that will be stored together with some other metadata on the IOTA tangle. We will also be creating a simple report that retrieves the same information from the tangle and displays it on a monitor.
