Brazilian retailer Grupo Pão de Açúcar (GPA) has said that it is testing new formats to optimise customer in-store purchasing time.
One initiative, dubbed 'pre-scanning', is currently being tested at a laboratory at Pão de Açúcar Jardim Paulista, in São Paulo.
This sees store employees equipped with a mobile reader approach customers to pre-scan purchases easily and quickly while waiting in line. The operator then starts to register the items, issuing a QR Code to the customer, with which they can pay for their items.
