> Like many other European countries, the Netherlands uses the Euro. Foreign currencies are usually not accepted. Amsterdam is still a cash society. However, these days you can pay almost everywhere with debit cards that use the Maestro, Cirrus or Plus system.
You do need your PIN code for that. Credit cards (VISA and MasterCard) are accepted in many restaurants and hotels, but many shops, cafés, museums etc. still don't. However, you can get Euros from the many ATMs in the city with a debit or credit card that uses the Maestro or Cirrus system.
