Abstract: A system and method for collecting information about a mobile device and associating it with a user. At least a portion of data about a user may be encoded into one or more images, along with optional commands or parameters for activating an app or other software or hardware modules of the mobile device. The image may be scanned by the mobile device, causing the mobile device to decode the data from the image, and to optionally automatically send the data back to the system thus confirming that association between the mobile device and the user.
