Some stores in China have found a really fun new way of pulling in shoppers and marketing themselves at the same time. They’re doing this with a special selfie printer that connects with WeChat. Scanning a QR code on the Welomo printer’s screen automatically adds Welomo’s service account to one’s WeChat contacts list. After selecting a photo to print, users input the four-digit code for the nearby Welomo printer into the chatroom space. The printer then churns out the selfie.
