Author | Jaime RamosThe way in which we choose our political representatives has hardly varied in the last few decades. A vote is still a vote. Practically all around the world, citizens go to their public centre to vote, they choose between ballot papers or they mark a series of options on these, they insert them into an envelope and deposit them in a ballot box.This liturgy forms part of the very essence of democracy. Technology has barely managed to change the details of this human ritual. And that is not because there are no electronic solutions available and capable of offering guaranteed transparency.The first technologies to prove that electronic voting was possible, emerged in the 1960s. They were optical scan voting systems or making use of perforated ballot papers. Since then, other methods have been developed to replace the original system, preserving the guarantees thereof.
