    I need a single QR code that will live on my printed materials and, whenever it’s scanned from an Android device, open a specific webpage in the phone’s browser. Stability is everything—the graphic must remain valid for years—so the method you use has to account for possible future moves or updates I might make to the destination without forcing me to reprint the code. You will receive the final URL as soon as we start. From there, please create the code, test it with the usual Android scanning apps, and hand back artwork I can drop straight into flyers, packaging and any other promotional assets. Deliverables • QR code supplied in scalable SVG plus a 300 dpi PNG • Proof it resolves correctly on at least three mainstream...
