Nothing to download and nothing to touch." --- # Contactless Technology QR code experiences on the guest's own phone: photo walls, treasure hunts, arcade games and Web AR. Nothing to download and nothing to touch. ## QR code experiences on the guest's own phone With contactless technology, visitors take part using their own phone. They scan a QR code and the experience opens in the browser, with nothing to download, nothing to touch and no queue for a shared screen. Because everything runs on the web, hundreds of guests can join in at the same time, and the same activation can work at one venue, across several locations at once, or for guests who join from somewhere else. We design and build these web apps in Dubai, with the screens, the content and the branding made for your event. ## QR photo wall Guests become part of a picture that grows on the big screen. It works in three steps: 1. **Scan.** Guests scan a QR code with their phone. 2. **Snap.** They take a selfie or upload a photo. 3. **See.** The photo appears in full size on the screen, then moves to the spot of the code they scanned and replaces it. For the [Department of Health in Abu Dhabi](https://echt.me/projects/qr-photo-wall-department-of-health-uae-national-day-event), the wall ran on an LED screen ten metres wide for the UAE National Day. The photos of guests and employees came together as one large mural, which was later shared on social media.

For [Novo Nordisk in Riyadh and Jeddah](https://echt.me/projects/qr-treasure-hunt-team-building-activity-rebel-mission), 450 employees played five missions over five weeks for a product launch. The missions included finding codes hidden in the offices, selfies, a timed puzzle and a slogan contest.

[More about the Media Station](https://echt.me/products/interactive-and-contactless-media-station) ### Phone-controlled arcade games Classic arcade games on the big screen, played by several visitors at once, each using their own phone as the controller. A leaderboard keeps people coming back.

Netflix used it for a [popcorn box that comes to life](https://echt.me/projects/webar-popcorn-box-netflix-masameer-county) in cinemas across Saudi Arabia, Nissan for an [AR art gallery in Jeddah](https://echt.me/projects/web-augmented-reality-art-gallery-nissan), and Gallery Eden for [animated artworks in The Dubai Mall](https://echt.me/projects/augmented-reality-art-gallery-eden-web-app).

For the opening of the first Jordan store in Dubai, more than 700 drones drew a QR code in the night sky above the Dubai Frame. It led to our [appointment booking platform](https://echt.me/projects/nike-jordan-store-opening-in-dubai-mall-appointment-booking-system) for the opening week.

No. Guests scan a QR code with their phone's camera and the experience opens in the browser. ### How many guests can take part at the same time? Everyone uses their own phone, so nobody queues for a shared screen. For Novo Nordisk, 450 employees played a QR treasure hunt over five weeks, with a live leaderboard. ### Can one activation run in several places? Yes. Because it is a web application, the same activation can run at one venue, in several offices or cities at once, or for people who join from elsewhere. Novo Nordisk's treasure hunt ran in Riyadh and Jeddah. ### What can a QR code activation be? A photo wall that grows on a big screen, a treasure hunt for team building, arcade games played with phones as controllers, a media station controlled from the phone, or augmented reality that opens from the code. ### How early should we get in touch? That depends on the project. For many formats we do not start from scratch. We build on a proven framework and adapt it to your design and content, which saves time. A completely new development needs longer for design, development and testing. Contact us as early as you can, and we will tell you what is realistic for your date. ### Is your team on site at the event? Yes. We set up and test the installation and support it on site, in the UAE and abroad.
