Quick Response (QR) codes are popping up around retail spaces more and more these days. I once saw them as a gimmick, but after watching a video about how Tesco, a South Korean grocery store chain, grew their customer base by 76% by using QR codes, I am now a believer. Tesco replicated grocery shelves with QR codes placed under every item, and posted them on billboards in subways - essentially bringing the grocery store directly to the consumer. Since South Koreans work long hours, Tesco needed a way to reach customers that are not able to make it to the physical store between commutes. With the Tesco subway billboards, customers are able to scan the QR code and immediately have their groceries delivered to their homes. Within a few years, QR codes will be an integral part of retail spaces and essential for experiential marketing campaigns.
