The U.K.’s data-protection watchdog said it’s investigating a cyberattack at Dixons Carphone Plc that affected almost 6 million payment cards.

The retailer, already struggling with a slowing mobile-phone market in the U.K. and the rise of Amazon.com Inc., said 1.2 million records containing nonfinancial information such as names, addresses and emails were breached.
