        QR Code (quick-response code)

        Please Note:
        • QR code can be generated in the following different modes: Numeric, Alphanumeric, Byte, Kanji, ECI, FNC1 plus some others.
          However, since Numeric mode can encode only numbers, Alphanumeric mode can encode only numbers, uppercase letters and
          only a few other characters, and Kanji mode is most appropriate for Kanji characters, we are using Byte mode exclusively.
        • While QR can encode UTF-8 (unicode) characters, some QR readers (decoders) might not support them and will not properly decode them.
        • By default, we are using he highest possible error correction level to produce the most reliable code, but you can use the lesser error correction
          level which will generate a smaller code and thus allow the encoding of a greater number of characters. High error correction level allows a
          recovery of up to 30% of the data but you can encode at most 1,273 bytes. Low error recovery level can encode up to 2,953 bytes, but only
          7% of the data can be recovered. If you use non-ASCII unicode characters the number of encoded characters can be significantly less.
