The Shopitize app, which is available on iOS and Android devices, enables users to scan their shopping receipts and receive discounts from participating partners.
As part of the deal, users will receive 50% cashback on the price of products including McVitie's Jaffa Cakes, Special K and Crunchy Nut cereals.
Consumers will receive cashback via PayPal or cheque. It launches with the brands this week and will be promoted via iTunes and Android Marketplace, as well on tech review sites.
Shopitize claims that brands will be able to offer consumers more targeted deals and offers, based on shopping behaviour, as more users sign up to its app.
Mobile payments and couponing is gaining traction in the UK, particularly with the increase in consumers seeking to purchase items on smartphones and looking for paperless transactions.
Google offers a paperless coupon service through its Google Offers mobile payments. However, this is yet to launch in the UK. O2 launched a similar service earlier this year.Follow @shearmans
