QR Stream Generator

The Go implementation of QR stream generator. This utility is used to encode any small files into a series of QR codes, named "QR stream". Then user could use a scanner (normally a mobile phone) to decode the QR stream to get the original file. This is useful when there's a networking barrier between the user and the server inside a private network. It helps for sharing files in such situation.

Try the demo QR stream scanner below:
