This is a great video of how one retailer is taking itself to the consumer using QR codes. The video shows people shopping while waiting for the subway in South Korea where the virtual displays and the merchandise is identical to what a customer would see in the store. By using smartphones a shopper can scan the products QR codes and place it in the basket and the grocery bags are delivered to their home. Essentially, for busy South Koreans, they can shop while they wait. This is the wave of the future for virtual stores and QR codes and for retailers who are contemplating whether to open another brick and mortar they should consider following the trend being set by the most connected people in the world.
