QR Codes have been around for a while but adoption in the US has been slow. In South Korea, where they’ve caught on, the grocer Tesco has figured out how to combine QR codes, mobile phones, and downtime to make day-to-day lives better. What did they do?

The brief video below shows how they leveraged a mix of technology, market insights, and strategy to rebrand themselves and provide people with a solution that actually made their lives better.
