MinQRReader

This is a minimum required QR code reader.

This is a tiny QR code reader.

This can read one-dimensional bar code too.

This has only the minimum required permission.

This can call associated applications when a code is read.

This also can be called from other applications.

This also supports the following links.

zxing://scan/?ret=[URL] OR http://zxing.appspot.com/scan?ret=[URL]

[PS] I made an app to launch the browser after QR reading immediately.
