What is 3QPR?
3QPR (3D Quick Prompt Response) is the physical-to-AI bridging platform. A QPR Code is a QR code with an embedded AI prompt — scan it with any camera and you're instantly in an AI conversation, no app download needed.
Use cases span retail (product assistant), hospitality (concierge), events (networking), healthcare (prescription info), and anywhere a physical touchpoint should become a conversation.
