QR codes can hold up-to 2.9 kb binary data (or up-to ~7 kb numerics only). For more info, click here.

The amount of data that can be stored in the QR Code symbol depends on the datatype (mode, or input character set), version (1,...,40, indicating the overall dimensions of the symbol), and error correction level. The maximum storage capacities occur for 40-L symbols (version 40, error correction level L), and are as follows (where character refers to individual values of the input mode/datatype, as indicated):

Numeric only    Max. 7,089 characters (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)
Alphanumeric    Max. 4,296 characters (0–9, A–Z [upper-case only], space, $, %, *, +, -, ., /, :)
Binary/byte     Max. 2,953 characters (8-bit bytes) (23624 bits)
Kanji/Kana      Max. 1,817 characters
