Canada's premier retail brand uses Postilion to standardize payment capture across POS

NORCROSS, Ga. and TORONTO, Feb. 5 /PRNewswire-FirstCall/ -- Postilion, a leading provider of integrated software solutions for payments processing and self-service banking and a division of S1 Corporation (Nasdaq: SONE), today announced that Canadian Tire Corporation, one of Canada's most-shopped retailers, has implemented Postilion for Retailers to enhance in-store transaction security, simplify operational management, and provide the foundation for EMV chip acceptance.

The Postilion solution enables payments from Canadian Tire Retail's 473 stores to be seamlessly integrated with retail functionality at the POS. All aspects of EMV chip and PIN payment processing will be handled by the integrated solution, standardizing the payment capture mode across the store network. Transactions will be submitted to a centrally located payment switch for online authorization via the integrated POS.

Postilion for Retailers can deliver faster transaction processing times than those associated with older technologies, and eliminate the need for dial-up lines. The solution is PABP certified, thus simplifying PCI DSS compliance programs.

"Postilion has proven to be a key partner in helping us build out our payments systems strategy, and has enabled us to offer new payment methods and channels," said Rick Bankes, Vice President, Information Technology, Canadian Tire Financial Services. "The breadth of the Postilion solution has allowed us to address EMV compliance, while simplifying our payments infrastructure, and gives us the flexibility to meet future payments needs."

"We are pleased to be a part of the successful implementation and launch of Canadian Tire's EMV chip card acceptance program," said Doug Parr, General Manager, Postilion Payments Americas. "Our open-systems payments software solution provides the agility that large retailers like Canadian Tire need in order to respond to new business functionality demands while maintaining a reliable, compliant payments systems infrastructure."
