The mobile solution provider AIRTAG has partnered with the Madrid-based multiformat grocery chain DIA on a program dubbed "Diadiscount," which includes a mobile wallet for ordering and payment and a system of refrigerated lockers for customer pickup.

DIA is now using AIRTAG's AIRSHOP mobile commerce platform, which enables retailers to launch self-branded wallet apps with customized functionalities.

With an iPhone app, Android app or mobile website, DIA customers can order groceries from a list of more than 1,300 products and pay online before they arrive at the store. During checkout, the customer chooses a preferred order pickup time, then retrieves the order from the locker by entering a confirmation number that acts as a key to open the locker. 

The program is now piloting in Paris, with the first 300 customers who place an order using Diadiscount receiving a special prize.
