PDF417 is a stacked linear barcode format used in a variety of applications such as transport, identification cards, and inventory management. "PDF" stands for Portable Data File. The "417" signifies that each pattern in the code consists of 4 bars and spaces in a pattern that is 17 units (modules) long.
MicroPDF417 has high encoding density and in this way, it can add more additional data in lower space. At this time, it is used in inventory management and goods labeling as part of EAN.UCC Composite Symbology [9] and GS1 Composite barcode symbology. [5] Most of barcode printers [10] and barcode scanners [11] have MicroPDF417 support.
Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
One advantage of Code 39 is that since there is no need to generate a check digit, it can easily be integrated into an existing printing system by adding a barcode font to the system or printer and then printing the raw data in that font.

GS1 introduced the barcode in 1974. [8] A barcode encodes a product identification number that can be scanned electronically, making it easier for products to be tracked, processed, and stored. Barcodes improve the efficiency, safety, speed and visibility of supply chains across physical and digital channels.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner , it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals.
