On Brazil's electronic vote machines (voting is compulsory here, and almost all of it on these machines), there is even an explicit (and quite big, though all the buttons on these machines are big) "blank vote" button. You can also cast a null/invalid vote, but it is a bit more hidden; simply type any number which does not match a party or candidate (like "99" or "00") and it will be accepted as a null/invalid vote.
