The perfect consumer touchpoint for an increasingly mobile device-driven world is your smartphone. Imagine GROCERY SHOPPING at store shelfs in your local subway station using your phone! Or using similar technology and virtual shelves on-line in the convenience and privacy of your home. In South Korea, where upwards of 70% of adult workers are forced to use the subway system due to infrastructure and lifestyle - what better place to launch a virutal shopping experience using mobile phones and yes, virtual store shelves. Retail shopping giant Tesco launched this in South Korea this past year - and it IS proving to be a smashing success. Here is the video that showcases how it all works with your phone and why it is so on-point with the shopping habits and lifesyles of consumers there.
