This paper introduces the implementation of IoT based event management system using RFID. These days Security has become crucial in sensitive areas like Meetings and many places where VIPs attend, the event managers need to log the entry of the guests to ensure no outsiders except invites are attending the meet. It’s not easy for a person to manually log the entry of attendees with their entry time, and these days due to COVID-19 Pandemic everything is being contactless so it is not even possible to use fingerprint sensor and the fingerprints of the attendees need to be pre-registered, this may be not possible in many cases. In these cases, the IoT- based Event Management System using RFID plays a vital role in logging the entry of the attendees, this requires no human intervention and ensures contactless procedure. The details of the attendees are encoded in the RFID cards and they are given to attendees as the entry pass to the event, at the entrance the attendees need to place the RFID card before the RFID reader, the RFID reader decodes the information in the RFID Card and displays the name and place of the attendees, using NodeMCU the System can be connected to the internet and data can be retrieved from the ThingSpeak Server which is pre-configured by the event organizers, and the entry time of the attendees will be stored internally which can be retrieved from ThingSpeak Server. IoT-based Event Management System not only tracks the entry log but also sends the log and entry data directly to a dedicated server that can handle all of the authentication, authorization, and management. This helps in monitoring the Sensitive areas and to log the entry of invites.
