The document proposes a mobile advertising campaign called "Make a Pause" Treasure Hunt for Twix. QR codes showing idyllic destination images would be displayed around London. Scanning all codes from a destination would enter users to win a trip there. The first 5 people to complete destinations win. Users upload scanned images to a microsite to track completion. Rewards like warm/cold hints keep users engaged. The campaign aims to demonstrate Twix supports pausing and sharing positive experiences with friends could increase brand perception and sales. QR code scanning is fast and accessible on most phones to enable participation.
