Girocard
Girocard is an interbank network and debit card service connecting virtually all German ATMs and banks. It is based on standards and agreements developed by the German Banking Industry Committee.
German Girocards are usually co-branded with MasterCard's Maestro/ Cirrus or VISA's V PAY logo, allowing cardholders to use them in other European countries. As another co-badging option, combined Girocard/ JCB cards were introduced in 2016.
