The month-long member appreciation celebration at the $794 million Columbia Credit Union in Vancouver, Wash., included the chance to scan to win. Along with the mix of cash prizes, product specials and community events were QR (quick response) codes posted in branches where members with smartphones could scan their entry. “QR code technology is an extremely versatile and cost-effective marketing tool,” said Colleen Boccia, the 70,000-member credit union’s senior vice president for marketing and chief deposit officer. “We’re excited to introduce members to this new technology and look forward to leveraging its capabilities in future mobile marketing campaigns.”
