Deqode by David Jonathan and Kevin Aust

This video is a promotional overview for Deqode, a new and innovative QR/Barcode prediction system created by David Jonathan and Kevin Aust. It's a tutorial-style video showcasing the core concept and a few of the many routines possible with this system. The creators are enthusiastic about its versatility and ease of use, emphasizing that it allows performers to secretly control where a QR code or barcode scans, effectively 'hacking' it in real-time. Several routines are demonstrated, including a grocery receipt prediction where a spectator freely chooses an item, a Smarties prediction, a custom card routine, and a top 10 movies routine. Deqode is designed for 'everyday carry,' quick to set up and easy to learn, and works on both iOS and Android devices. While the method isn't explicitly revealed, the core technique involves real-time redirection of scans, leveraging smartphones and scanning apps. The creators encourage experimentation and exploration, suggesting it's suitable for both serious mentalism and lighthearted comedy, and strongly discourage revealing the method to respect the work of other magicians.
