Abstract
A method of confirming receipt, including iteratively capturing by a receiving device visual codes in a series of visual codes displayed on a sending device. A corresponding captured visual code being from a display block that resulted from a partition of an original data file into display blocks, and wherein each display block is converted to a corresponding string and header including an ordered identifying display block number and a total count of the display blocks. Each corresponding string is converted to a corresponding visual code. Each of the captured visual codes is converted into a corresponding string and a header is read for the corresponding string. Captured display blocks are determined. A confirmation message is generated including information indicating which display blocks have been received. The confirmation message is sent over a wireless communication link to the sending device to reduce the number of visual codes being displayed.
