Smart-posters offer higher interaction versus their QR counterpart. With QR codes, the user has to launch an app, aim the camera to the QR code, scan or take a picture, and wait for the device to react. The light conditions, elements, age of the poster, etc. may interfere with the user interaction. With NFC, on the other hand, users simply tap on the poster to get the information (“Tap-to-Get”) stored on the tag (URLs, coupons, etc.). The information is transferred to the phone instantly, thereby improving the user experience (UX).
Smart-posters requires the smartphone to support NFC Discovery Mode which is currently limited to Android and Windows Phone mobile devices. Devices that support NFC Discovery Mode have the capabilities to read tags (and hence can read Smart-posters). Unfortunately, NFC-enabled iPhones don’t support Discovery Mode and can only emulate NFC tags. This is referred to as Card Emulation Mode. Without Discovery Mode support, the iPhone do not have the capability to interact with Smart-posters.
