The document discusses using QR codes to provide information during crisis events and disaster scenarios. It proposes printing QR codes that can be scanned by smart devices to access instructions, messages, media or trigger processes related to marked-up objects and locations. The approach assumes the availability of smart devices, data connectivity, a portable printing device, and that security is not a concern. The document outlines potential uses such as coupling codes with objects to provide information, triggering remote or device processes, carrying device identification, and using codes for authentication or logistics/resource tracking.
