In addition, the Barcode Scanner SDK supports a broad range of symbologies to meet your growing development needs. Packaged with the consumer product barcodes of EAN, UPC, PDF417, and GS1 Databar, the SDK Consumer Developer License (CDL) lets you deliver a powerful retail experience quickly and easily.

In addition to consumer marketing, it's utilized for product and time tracking, item identification, and document management. Directing consumers to a brand Website with a single scan and offering product loyalty rewards and coupons in exchange for gathering analytics it's seductive to consumers looking for product knowledge. Originally used in the automotive industry to track automobile parts, the QR Code has now become nearly commonplace in consumer marketing. Greater Security: They provide greater security than 1D barcodes, due to their ability to encrypt information.Easily Read: They are easily read with any smart phone.Fewer Errors: They employ much more robust error correction technology than traditional 1D barcodes in addition to having built-in error checking systems, they may still easily be detected and read if damage has occurred.Each barcode can store up to a 7,089 values. More Information: They efficiently pack more information in a smaller space as opposed to one-dimensional (1D) barcodes.The alignment patterns at the three corners of the image enables rapid reading, while the timing pattern allows for the code to be read even if distortion or damage has occurred. Error Correction: A portion of the data stored in the barcode is devoted to Error Correction Codewords, or ECC this sophisticated technology is used to detect and correct errors as well as help recover lost data (known as erasures).Data is stored in 8 bit parts, called code words, in the data cells. Data cells: Each individual black or white square that is not part of one of the standard features (the timing, alignment, and other patterns) contains data in the code.The version information simply identifies which version is being used in a particular code. Version information: There are various versions of this standard.

The timing pattern makes it easy to identify the individual data cells and is especially useful when the code is damaged or distorted. Timing pattern: The timing pattern consist of altering black and white modules that run horizontally and vertically between the three finder patterns.Alignment pattern: This ensures the code can be deciphered even if it's distorted.

The finder patterns enable the decoder software to recognize and determine the correct orientation.
