The Minister of Education stated that one of the reasons for the failure in digitizing national exams was the fact that teachers stapled the QR Codes.
The Funchal Notícias article questions this explanation, raising two points: why teachers felt the need to use staples and the robustness of QR Codes, which should function even with missing parts.
The text suggests that the need to staple may have arisen due to the number of loose sheets and the separation of continuity sheets for answers. Tests are conducted to see if a staple prevents QR Code reading, as alleged.
