GERMANY - When a little-known online payments firm from a small German town called Aschheim overtakes Deutsche Bank in stock market value, people tend to take notice. What makes Wirecard tick? It's as valuable as it is inconspicuous. This week, a little-known Bavarian payment processing company called Wirecard overtook Deutsche Bank to become Germany's most valuable financial services firm on the stock market. While traditional money houses like Deutsche battle to stay relevant in the smartphone age, Wirecard has already established itself as a serious player. The company provides software for online payments, contactless payments and fraud prevention systems and the German fintech success story is close to knocking Commerzbank out of the DAX index.
