The QR (quick response) code is a two-dimensional bar code, which can be read by any smartphone using a free reader program. It establishes a link with the product or service in question and the information available online. With its help, consumers can instantly access specific information after the scan without needing to search for anything. Growing in popularity for its user-friendly functionality, QR codes eliminate the need to search, visit a web address or call a phone number. Additionally, QR codes are cost effective and can be placed on any surface (advertisements, marketing collateral, business or promotional cards, flyers, product packaging, etc.).
