The QRCode decoder SDK is a robust, efficient and fast
library for reading/decoding, searching barcodes, and
detecting barcode orientation. QRCode barcodes can
store large amounts of data in a small symbol, up to a
maximum 7089 Digits,4,296 Alphanumeric,2,953
binary,1,817 Kanji characters. Unlike linear (1D)
barcodes, which are typically used to store a record
or account number which then must be retrieved from a
database in order to get additional information,
QRCode symbols can typically store all of the
information associated with a particular record. This
way, using QRCode barcodes, developers can eliminate
database information retrieval, and can simply read
all account details from the QRCode symbol itself.

Developers can read barcodes regardless of
orientation, skewing or flipping. Barcodes can be
detected and read from specific areas of interest. and
barcodes can be read from a variety of supported image
file formats and can be acquired from scanners or
digital cameras
