An Android library for scanning documents with two QR codes. Takes a photograph of the document, and uses the two codes to orient and scale the photo to allow it to be used as a way to interact with the document without the need for more in-depth image recognition.
Clone this repository and import into Android Studio. You can then make your own Dual-QR project by extending DecoderActivity, or try out TicQR or PaperChains instead.
Apache v2.0
This library is based on Android Quick-Response Code, which is itself based on ZXing.
