Abstract
Systems and methods for using optical barcodes without orientation for information access are provided. In example embodiments, a computer accesses an image including data encoded within a geometric shape. The computer decodes, for each of a plurality of orientations of the geometric shape, a first portion of the data encoded within the geometric shape. The computer determines that, for one of the plurality of orientations, the first portion of the data encoded within the geometric shape decodes to a predefined number. The computer determines that the one of the plurality of orientations is an intended orientation for the geometric shape. The computer decodes, based on the intended orientation of the geometric shape, a second portion of the data encoded within the geometric shape. The computer accesses, via a network, a resource that corresponds to the decoded second portion of the data.
