In 2026, the fine for traveling without a valid ticket or failing to "check in" on an Amsterdam tram is €50.00, plus the price of a single ticket (approx. €3.40). GVB (the public transport operator) employs mobile inspection teams that frequently board trams to scan cards. If you are caught without a valid "OV-chipkaart," a scanned bank card, or a mobile ticket, the inspectors will issue a "process-verbaal." You must provide valid identification, and if you cannot pay the fine on the spot via card, you will receive a bill at your home address (including international addresses). It is important to remember that you must check in AND check out at the card readers by the doors; forgetting to check out may result in a "correction fee" being deducted from your balance, though it is the lack of a check-in that triggers the major €50 penalty.
