The UK’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 UK and the rise of Amazon.com Inc, said 1.2 million records containing nonfinancial information such as names, addresses and e-mails were breached.
