Sending RFID Events in Real time w/ Tessel RFID Module

Radio-frequency identification (RFID) technology enables wireless data transfer for object tracking and identification, and its affordability has led to diverse applications such as Coca-Cola's use of RFID-embedded cups for refill authentication and Boeing's tracking of manufactured parts. This blog post, as the first part of a Tessel RFID module tutorial, guides users in setting up an authentication network using the Tessel microcontroller, which runs JavaScript. It details the process of detecting an RFID scan and sending information in real-time through PubNub's secure network. The tutorial includes practical instructions for preparing the Tessel setup, connecting to WiFi, cloning the necessary repository, and using the example file to publish messages. By initializing PubNub with unique pub/sub keys and running the provided code, users can observe successful RFID card readings denoted by a blinking LED, indicating proper device functionality.
