The tokens and cards are sold at ticket offices, which are found at subway stations. The token can be used at the station of purchase and for a certain distance only. Passing through the faregate you have to insert the token into the reader or swipe the card over it. Please, keep it throughout the ride as it has to be validated at the end of the trip.
