The building society is launching the card under its 'We're On Your Side' strategy as it seeks to acquire new customers for the Select card from the customer base for its FlexAccount, which is available to those who pay in at least £750 a month.
Direct mail, email and statement insert activity created by Kitcatt Nohr Digitas will launch today (16 February) to support the acquisition drive.
The card offers 0% interest on purchases for 18 months, unlimited commission-free purchases abroad, 0% balance transfers for 17 months and 0.5% cash back on all purchases.
Alastair Pegg, head of brands and marketing at Nationwide, said the card underlined the brand's commitment to the 'We're On Your Side' positioning.
