Important to mention that while tickets are only valid for the vehicles of BKV (Budapest Transport Plc.), cards are valid for most of the vehicles of BKK (Budapest Transport Center). BKK is an umbrella organization of which aim is to control everything related to transport in Budapest. So for example if you want to travel to Gödöllő (which is a town near to Budapest and famous of a Habsburg castle), and you travel by either couch or train, then if you have BKK card, then you have to pay only the outside Budapest part of your travel, which is – in case of Gödöllő – exactly the half of the full price.
