Getting around while in Poland

Public transport tickets can be bought only in advance from kiosks, not on the vehicle. This includes the metro, although there may be a small coin-operated ticket machines at the entrance. If you so much as set foot on the escalator leading down to the platforms without a valid ticket you are liable to a fine of about US$25. There is a small notice (only in Polish) next to the ticket machine which says so. The ticket inspectors are paid on commission, so they lurk at the foot of the escalators waiting for tourists looking for a ticket office. If you are caught, demand to see a policeman. Because they are paid on commission, they will grumble and curse, but will let you go because they don't want the hassle and delay involved and the risk of losing the fine anyway. But I don't know if this will work if you're actually on board. Best value is a one-day tickets (from a kiosk, for Pzl4 - aobut US$1) which gives you unlimited travel in the centre on all public transport.
