Abstract: Described are methods and systems for Virtual Multi-Dimensional Quick Response (VMDQR) codes, used for transferring data sets between code initialization devices and code retrieval devices, such as smartphones and other like devices. A VMDQR code is capable of encoding and sharing large amounts of data, regardless of the space available on an object. The amount of the encoded data depends on the dimensionality of the VMDQR code. A VMDQR code is incorporated into an augmented image, presented on a user interface of a code retrieval device. For example, an image of a real object, which does not have any physical codes, is augmented by adding a VMDQR code to give a representation of an object with a code. The VMDQR code is then scanned from the user interface using a scanner to transfer the encoded data to the scanner.
