-

i use script https://github.com/jeromeetienne/jquery-qrcode
(or there better solution?)

what "save" small scripts or programs , files xml formatted files (svg, x3d, ...) qr code images.

but how information (in bytes) can save qr code images (using javascript solution)?

any experience script , using qr codes files?
https://github.com/jeromeetienne/jquery-qrcode

qr codes have 3 parameters: datatype, size (number of 'pixels') , error correction level. how many information can stored there depends on these parameters. example lower error correction level, more information can stored, harder code recognize readers.

the maximum size , lowest error correction give following values:
numeric max. 7,089 characters
alphanumeric max. 4,296 characters
binary/byte max. 2,953 characters (8-bit bytes)
