In a warehouse, for example, incoming packages may bear dataforms of a variety of different types such as 1D bar codes, 2D bar codes and matrix codes. By use of image features distinctive for different dataforms, a hand-held reader is enabled to autodiscriminate among different 1D and 2D bar codes and matrix codes. If the sampled image data permits identification of a specific type of dataform, a decoder employing a suitable decoding protocol is used to decode the dataform. Iterative use of additional image features and sampling patterns increases the accuracy of dataform identification. Data decoded from each incoming dataform is recoded and autotranslated into a preselected standardized dataform label placed on each respective package. Subsequent reading of package dataforms thereby requires reading and decoding of only the single standardized dataform format. Systems and methods are described.
