Coles Myer is to fold its various credit cards into a single branded card.

The group's 1.7 million credit card customers currently use cards under four different brands: Myer, Grace Bros, Target and Kmart. They will all be folded under a single brand to be called the Coles Myer Card.

A new deal has also been struck with GE Capital Finance, which will provide credit facilities for the new credit card business. It is believed that the deal includes a joint marketing agreement.
