Contactless Tool for COVID-19 Surveillance System

Due to the COVID-19 pandemic, surveillance systems have been implemented to monitor public health and trace the infected individuals. The Malaysian government has imposed the standard operating procedure (SOP) which includes checking of temperature for fever, use of hand sanitizers, and record their name, contact number, and date of attendance at points of entry. This paper proposes a contactless tool for COVID-19 surveillance that integrates all the 3 processes into one. The system carries out each stage in sequential order for every person, starting with checking temperature, dispensing hand sanitizer, and lastly data profiling record. The temperature is done using infrared thermometry that automatically adjusts to forehead height. Hand sanitizer is automatically dispensed when hands are detected under the pump. Image processing and optical character recognition are used to capture the name and contact number that will be shown on a tag carried by the individual and saved to the database. The process is contactless and requires no human operator, and yields accurate temperature data, works as intended while demonstrating high accuracy and speed in extracting information with optical character recognition.
