The bright side is that Maestro cards are recognized worldwide, offering convenient access to money at home and abroad. They are especially popular in Europe with the largest European markets being Germany, Austria, the Netherlands, Belgium, and Switzerland.
You may use your Maestro card anywhere in the US that accepts MasterCard debit cards. You must physically have your card present and enter your PIN. However, Maestro cards may not be used in the US for online purchases. All US issued debit MasterCards work internationally on the Maestro and Cirrus networks.
