The aim of the project was the development of the online passenger locator form (digital PLF), which is a tool for recording and tracking the passengers traveling from one country to another during the COVID-19 pandemic. The use of this mechanism allows government agencies of EU countries to impose rules on who can enter each country based on personal data, where their journey began or the area in which they reside. At the same time, it allows the easier detection of COVID-19 cases and the limitation of the pandemic spread. With this system EU member states monitor the itinerary of each traveler and exchange information about active covid cases that have traveled from one country to another, in order to track infected people and stop the spread of Covid.
