The agency was appointed without a pitch following proprietary research conducted into the UK credit card market. It also contributed to brand naming and product research.
The Co-operative Bank's biggest launch campaign to date will include direct mail, press, posters, email, online and branch-based point-of-sale executions.
Kelvin Collins, head of marketing communications at the Co-operative Bank, said: "Clear Card is a very important launch for us and given the competitive nature of the market we need to achieve stand-out both in terms of the consumer benefits, product offering and brand awareness."
Clear Card will be offering a low long-term interest rate at 8.9% APR on all transactions and up to 59 days' interest-free credit. There will also be a 1.25p donation to the Bank's Customers Who Care programme for every £100 spent on the card.
David Morley, director at Iris, said: "Our experience in brand response and corporate responsibility marketing ties in with what the Co-operative Bank is looking for."
