Process: My process included four main steps:

Step 1: Find out the RFID tag UID by using arduino

Step 2: Segregate the UIDs for data that represent data that is sensitive v/s the data that is okay for being taken out. I maintained an excel sheet to keep track of it and used Particle cloud function to see if RFID was bein read properly as per these. For example, for Alexa, there were two functions: AlexaYes and AlexaNo.

This step also helped me learn that Particle by default removes the extra zeros in the RFID UID, and it was helpful in the next step.
