詳解

Class QRCode is a two-dimensional barcode library used to generate barcode with QRCode method.

QR Code is capable of handling all types of data, such as numeric and alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes. Up to 7,089 characters can be encoded in one symbol.

The capacity differs from each encode mode: Numeric only Max. 7,089 characters Alphanumeric Max. 4,296 characters Binary (8 bits) Max. 2,953 bytes Kanji, full-width Kana Max. 1,817 characters

Class QRCode supports 3 encode mode: Numeric, Alphanumeric, and Binary 8 bit
