QR Code Encoder

QR codes have data encoded inside them using QR code generators. These generators are online and make it simple to make a QR code with the user’s needs in mind. While conventional bar codes are only capable of storing twenty digits; QR codes are capable of handling up to several hundred times more information than the traditional bar code. QR codes can handle such data as numeric and alphabetic characters, Kanji, Kana, symbols, and control codes. QR codes hold up to seven thousand characters that can be encoded in one symbol.

A QR code or Quick Response code is a two-dimensional bar code that consists of black modules arranged sporadically in a square pattern on a white background. QR codes were created by Toyota subsidiary Denso-Wave in 1994 to track vehicle parts in the manufacturing process. QR codes can be decoded at high speeds and are the most popular two-dimensional bar codes.

There are numerous standards when the physical encoding of QR codes is taking place. The amount of data stored in the QR code encoder depends on the version, the character set and the error correction level.

A QR code encoder records two things, the error correction level and the mask pattern used. Masking is used to make scanners work more efficiently by breaking up the pattern. The black modules corresponding to the dark areas of the mask are then inverted; this is complicated by the alignment patterns and multiple interleaved error correction blocks.

At the highest error correction level it makes it possible to create visually appealing QR codes that can still scan correctly. A QR code encoder can also incorporate logos, colors, and brand. This assists companies to get advertisements or promotions to a larger consumer base.
