It’s a variant of PDF417‚ sharing encoding and error correction features‚ but with a smaller footprint.
History and Development
Micro PDF417 emerged in 1996‚ a brainchild of Frederick Schuessler‚ Kevin Hunter‚ Sundeep Kumar‚ and Cary Chu from Symbol Technologies. This two-dimensional barcode symbology was designed as a space-saving alternative to its larger counterpart‚ PDF417‚ addressing the need for high data density in compact spaces. Initially‚ the standard was exclusively available through AIM (Automated Identification Manufacturers) as part of its ITS (International Telecommunications Standard) MicroPDF417 standard. Its adoption was spurred by the limitations of traditional 1D barcodes in handling extensive data sets. The evolution of Micro PDF417 reflects a continuing demand for more efficient data encoding methods within applications with limited space‚ such as identification cards and small labels.
