In South Korea, where people are always busy and on the go, Tesco Homeplus is bringing its grocery store products to consumers. Subway installations that mimic the aisles of a grocery store feature a QR code next to each product. Scan a product with your smartphone and the product automatically goes to your online shopping cart. Once you check out, your groceries will be delivered to your home.
I love the simplicity of this campaign – enable people to shop while they wait. How productive!
