Grocery shopping always turns out to be a 'task' you have to do may be once a week. Its a time consuming job and a lot of people actually don't like it. 'Tesco' an international U.K. based grocery chain called Home Plus in South Korea, came up with a genius new way to make shopping a more easy task by adding the virtual element to it.
Home Plus actually plastered posters which have images of groceries on the walls of subway station labeled with a unique QR code for each product. For those who don't know, QR codes are 'quick response codes', a boxy geometric image that actually represents information about the product like price etc. So basically as commuters pass by these poster on their way to work, they can use a mobile phone app to scan the QR codes of the products they would like to buy. The products automatically land in the online shopping cart then users can check out. The groceries are automatically delivered to their doorstep by the end of the work day. So all you do to shop is scan QR codes of the products you want.
