Abstract: A hybrid two-dimensional barcode reader decodes control features of the hybrid-two-dimensional barcode image, the control features corresponding to control features of a first formatting standard. The hybrid two-dimensional barcode reader extracts a data sequence from a data portion of the hybrid two-dimensional barcode image based on the decoded control features and a second data format different from a first data format of the first formatting standard to recover the first data set. The hybrid two-dimensional barcode reader may decode a second data set from the data portion of the two-dimensional barcode in the data encoding format of the first formatting standard. The hybrid two-dimensional barcode reader may also constellation decode the first data set.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a high efficiency data decoder. The high efficiency data decoder accesses an encoded data input from an input device and determines that the encoded data input does not map to any predetermined data outputs from a set of predetermined data outputs. The high efficiency data decoder selects, based on a ranking of modifications for the input device, a modification to perform on the encoded data input. The high efficiency data decoder performs the first modification on the encoded data input, yielding a modified encoded data input. If the modified encoded data input maps to a first data output from the set of predetermined data outputs, the high efficiency data decoder decodes the encoded data input into the first data output.

Abstract: A two-dimensional barcode encoder generates the hybrid two-dimensional barcode image that has control features corresponding to control features of a first formatting standard. The barcode encoder encodes a first data set in a data portion of the two-dimensional barcode in a second format that is different from a data encoding format of the first formatting standard. The encoder may also encode a second data set in the data portion of the two-dimensional barcode in the data encoding format of the first formatting standard. The encoder may also constellation encode the first data set.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a high efficiency data decoder. The high efficiency data decoder accesses an encoded data input including an ordered set of individual values and determines whether the encoded data input maps to any of a set of predetermined data outputs. If the encoded data input does not map to any of the predetermined data outputs, the high efficiency data decoder modifies at least one individual value from the ordered set of individual values, yielding a modified encoded data input. The high efficiency data decoder then determines whether the modified encoded data input maps to any predetermined data outputs. If the modified encoded data input maps to one of the data output, the high efficiency data decoder decodes the encoded data input into the identified data output.
