12 How much information can a DCNote contain ?

A full-resolution DCNote is 2480 x 1395 pixels bitmap - that means every pixel is a 1 bit of information (black or white).

That gives 3,459,600 pixels/bits = 432,450 bytes = 432 kB file
similar to a number of letters in an average 250 pages novel.

The above is true for computer-readable information.
As for human-readable text, about 500 words fit comfortably into a DCNote space - together with images and other data, while leaving plenty of space all around - a very efficient, digital/physical communication vehicle !
