Harry’s Bar in Singapore introduced ‘Bottle Message’ to make it easy for shy locals to meet each other at the bar. QR code tags on the beer bottles let you enter a message when you installed the app and scanned the code. Once the message was written, the tag was flipped over, placed over another bottle and sent to the admired person. Turning a beer bottle into a new form of communication caused beer sales to double at the bar.
