The Barcode Scanner can automatically search the Web to identify a product with a barcode and use, for example, price-comparison information between vendors. The application can decode several 2D barcodes including the widely used QR Code and Data Matrix. QR codes are often embedded in websites; Barcode Scanner can open a browser at the encoded ...
MicroPDF417 barcode allows to add metadata [3]: AnnexH to the barcode symbol which can add description of current barcode symbol. However, because MicroPDF417 has restricted amount of capacity it is used rarely. Some structured append fields cannot be omitted and set in case structured append is added to the symbol, some fields are optional.
Symbol Technologies, Inc., was an American manufacturer and supplier of mobile data capture and delivery equipment. The company specialized in barcode scanners , mobile computers , RFID systems and Wireless LAN infrastructure.
PDF417 is a stacked barcode that can be read with a simple linear scan being swept over the symbol. [4] Those linear scans need the left and right columns with the start and stop code words. Additionally, the scan needs to know what row it is scanning, so each row of the symbol must also encode its row number.

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.
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.
It enables the application software to receive additional information about the intended interpretation of the message contained within the barcode symbol and even details about the scan itself. ECI was developed as a symbology-independent extension of the Global Label Identifier (GLI) system used in the PDF417 bar code.
