BNP Paribas and retailer Carrefour are testing a mobile payment/loyalty app, jointly developed by the two entities. A mobile app called Wa! has been created for the trial, set to take place over the next few months in the Greater Paris region at a dozen Carrefour outlets. Using their PIN code, customers will be able to pay for purchases both at physical retail outlets and online, while being able to claim their usual loyalty benefits. Other retailers are being invited to take part in the initiative. BNP Paribas CEO Jean-Laurent Bonnafe, said the bank and Carrefour are delighted to be able to offer the market this disruptive innovation, which is fully secure and based on customers’ new needs and expectations. He said the technology platform is already operational.
