What is believed to be the biggest credit card recall ever in Europe is underway in Germany after the theft of card users details from a payment processing centre in Spain.The problem came to light when Visa and Mastercard noticed inconsistencies on people’s monthly statements. At least 100,000 people have been told they will have to be issued with new cards. One them, Karin Henkel, said: “Honestly I was shocked, because I never thought something like this could happen. We have used this credit card for years and nothing like this has happened before.” Andreas Martin, spokesman for ZKA, the body that oversees credit cards in Germany, said: “This is a big replacement campaign, it may even be the biggest ever. Several credit card companies, international companies, with card holders who were in Spain at the time in question have been affected, but we don’t have all the information yet.” Customers of nearly all the banks in Germany have been affected. The card replacement has particularly focused on Germans who have used their cards in Spain recently. It is not clear if the details of card holders from other countries have been compromised.
