Many innovations have been made in the field of contact tracing and tracking. However, studies have shown that there is no holistic system that integrates the overall process from data collection to the proper analysis of the data and actions corresponding to the results. It is critical to identify any contact with infected people and to ensure that they do not interact with others. In this research, we propose an IoT-based system that provides automatic tracking and contact tracing of people using radio frequency identification (RFID) and a global positioning system (GPS)-enabled wristband. Additionally, the proposed system defines virtual boundaries for individuals using geofencing technology to effectively monitor and keep track of infected people. Furthermore, the developed system offers robust and modular data collection, authentication through a fingerprint scanner, and real-time database management, and it communicates the health status of the individuals to appropriate authorities. The validation results prove that the proposed system identifies infected people and curbs the spread of the virus inside organizations and workplaces.<\/jats:p>","DOI":"10.3390\/s22249902","type":"journal-article","created":{"date-parts":[[2022,12,16]],"date-time":"2022-12-16T03:55:39Z","timestamp":1671162939000},"page":"9902","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["An IoT-Based Wristband for Automatic People Tracking, Contact Tracing and Geofencing for COVID-19"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5454-7069","authenticated-orcid":false,"given":"Sharanya","family":"Mahapatra","sequence":"first","affiliation":[{"name":"School of Electronics Engineering, Vellore Institute of Technology, Chennai 600127, India"}]},{"given":"Vishali","family":"Kannan","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, Vellore Institute of Technology, Chennai 600127, India"}]},{"given":"Srinidhi","family":"Seshadri","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, Vellore Institute of Technology, Chennai 600127, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5097-6189","authenticated-orcid":false,"given":"Visvanathan","family":"Ravi","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, Vellore Institute of Technology, Chennai 600127, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4057-1911","authenticated-orcid":false,"given":"S.","family":"Sofana Reka","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, Vellore Institute of Technology, Chennai 600127, India"},{"name":"Centre for Smart Grid Technologies, Vellore Institute of Technology, Chennai 600127, India"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13","DOI":"10.1002\/hbe2.242","article-title":"Digital technology use during COVID-19 pandemic: A rapid review","volume":"3","author":"Vargo","year":"2021","journal-title":"Hum.
