Digital Outing System Using RFID And Raspberry Pi With MQTT Protocol

In this paper, a model of digitally controlled outing system is presented. The system is an application of the Internet of Things (IOT) which works on RFID (Radio-Frequency Identification) technology. The system can replace the traditional way of maintaining the records for the entries of the students or workers in an institution or organization. It's an effort to digitalize the traditional way which is not so much reliable and efficient. This paper presents the design and implementation of a low cost and flexible outing system based on hardware devices like Raspberry Pi, NodeMCU, MFRC552 Card Reader and software tools like Django, SQLite and Python scripts. This paper presents the efficient working of the system.
