Números binários, corpos finitos e divisão polinomial, construindo um QR Code

Through a bibliographical review, we present all the processes of how a QR Code model 1, version 1, is made and the mathematical theories involved, making it possible to create a functional QR Code. We comment on how to write the data in the form of binary numbers, the correspondence between writing a number in base ten and in base two (binary). We emphasize the subject of finite fields, with a polynomial view, this subject being necessary to write the error correcting code data into a QR Code.
