A data breach in Spain has caused Visa and MasterCard to warn banks of possible fraudulent credit card transactions.

The breach likely affects people across Europe who may have had transactions processed in Spain. As a result, many German banks have opted to replace their customers’ cards, according to the Central Credit Committee, an organization that represents several German banking associations.

Banks in Austria, Sweden and Finland have also issued new cards, according to a report on Wednesday in the Stuttgarter Zeitung.
