Hi there,
In first, sorry if my English is not perfect, English is not my native language.
I would like to introduce you a concept to backup data on qrcodes called QRaidCODE. This tool is for printing data with parity on qrcodes which allows to create more qrcodes than necessary to decode your data. The data are encrypted and this concept helps to prevent theft and loss of your data.
For instance, you can create 3 qrcodes of data and 2 qrcodes of parity, you will only need 3 qrcodes by 5 to decode the data.
I'm working on this tool from few months and there is a online demo available :
https://goldy.furry.fr/qraidcode/ DO NOT USE THIS DEMO WITH YOUR ACTUAL WALLET! the script is server side and I can't guarantee that your data will be safe.
I'm working on an opensource portage in Javascript (node.js for the server and node-webkit for the stand alone app).
Any comment will be greatly appreciate.
If you want to support the development of this project, you can send me some tips to this address : 1Go1dy1GRBAHbPUTu6xPaWPSqQPd4DzU2i
Thanks for your interest.
