The benefits of a Postilion platform for a sizeable group like The Co-operative are numerous, particularly when working with an industry leader such as TNS. We work with TNS on many different levels through our payment services and work incredibly well with them. TNS manages each element of the Postilion platform with great ease and maximum effort which only an experienced provider can do given the extensive amount of traffic we experience.

Co-operative Group Chooses TNS for Outsourced ACI Postilion Solution


The Co-operative Group is the UK’s largest mutual business, owned by more than seven million consumers. It is the UK’s fifth biggest food retailer, the leading convenience store operator and a major financial services provider, operating 4,800 retail trading outlets and employing more than 100,000 people with an annual turnover of over £13 billion. The Co-operative Group’s payment processing platforms had evolved dramatically over the years due to the growth in card payments, new stores and additional payment types. With the added complexity of PCI DSS certification, The Co-operative Group made the decision to simplify its infrastructure and processing systems by selecting TNS to provide a fully outsourced solution for its retail stores and service stations using the ACI Postilion platform.

Business Challenge

The Co-operative Group had been running its own payments system in-house for a number of years and with the acquisition of Somerfield Supermarkets it also acquired an ACI Postilion payments system. The challenge of PCI DSS meant that significant effort and expertise was required to upgrade the payment systems of both The Co-operative Group and Somerfield. As with many retailers, unmasked card details were being stored locally in the store payment systems, which necessitated a major upgrade of the entire payment infrastructure within The Co-operative Group. Data centre facilities also had to be migrated for business reasons,which added to the scope of work, all of which had to be resolved quickly to enable PCI DSS compliance to be achieved.
