 +The team would like to thank the Instituto Superior de Engenharia do Porto (ISEP) for making their facilities available to us, and the teachers of the European Project Semester (EPS) for sharing their experience with us during this semester. We are grateful for the opportunity to participate in this project.

 Our team consists of 5 students from 4 different countries, namely Portugal, France, Romania and Poland. Our main mission is to make team work our main strength in order to create a positive work environment and achieve all established goals. In this sense, our main objective is to carry out a project that helps to organize events (in this case festivals) and in this way that overcrowding is avoided as much as possible, which is quite desirable nowadays due to the pandemic. Our team consists of 5 students from 4 different countries, namely Portugal, France, Romania and Poland.

-All team members are from different areas of study and we will make this one of our greatest strengths, taking advantage of the different experiences, knowledge and skills of each one. During these 5 months we will do our utmost to obtain the desired results and carry out a good project. **Table {{ref>flabel2}}** displays the team members.+All team members are from different areas of study and we will make this one of our greatest strengths, taking advantage of the different experiences, knowledge and skills of each one.

   * In order to maximise the impact of our promotion, we will target festival organisers directly, who are often responsible for several festivals at the same time. We will create a website where we will offer a video presentation of our scanner, a pdf leaflet and the user manual to show how it is used.

 It is important to define a marketing budget in order to have a clear idea of the costs that will be incurred. The duration of the marketing campaign, the internal and external costs, the type of communication you want to implement and its cost are defined.

 The team wanted to implement the idea of solar panel charging in the device to use it for outdoor festivals. On our list of materials there was a portable monocrystalline silicon solar panel in a PET package, with an integrated voltage regulator output of 5V with a USB plug. It can supply plenty of power in various environments to prevent the system from shutting down.  The team wanted to implement the idea of solar panel charging in the device to use it for outdoor festivals.
