Does you country have an official ID card?
We have our "Cédula de Identidad". It's mandatory for all, free, and expires every so often, so you must renew it.
One must always carry it, and we use it to vote and basically for every legal and banking process and for anything that needs your identity to be validated. From entering a National Park, to acquiring a cellphone line, to enter a gated community... we use it a lot!!!
(I just realized the US doesn't have one! And got me wondering)
