Micro QRCode
Micro QR Code is a 2D barcode readable by most QR scanners, mobile phones and
smart phones with a camera. The code is similar to QR code although is restricted to 35
characters
Numeric only
Alphanumeric
Binary (8 bits)
Kanji/Kana
Note: The number of characters is also affected by the error correction. The above
assumes the default level L is used.
Note: Lower case alpha is processed as binary data. URL information works best in
upper case.
Note: At this time Kanji and Katakana are not supported by the EPIC 3000
Micro QRCode is controlled by the same commands as QR code. Error correction level
H is not available as the number of correction characters would exceed the input length.
Micro QRCode Commands
There are two version of the command, one is null terminated and the other allows a
length to be specified (Note that the length is a two byte field as the symbol may contain
more than 256 characters.
