\section{Android Verification App}
The android app is part of the verification process used by the tax authority to check the donation statement (see xx).
+It is possible to define an URI scheme for an android app. The app opens when the link is activated. The arguments defined in chapter Protocol xx are separated with ??? %FIXME: should the length of binary data also be included?
+
+To ensure that as many characters as possible can be stored in the QR code, the QR code should be alphanumeric encoded \footnote{alphanumeric encoded QR codes have a capaticity of up to 4296 characters and support only a few special characters}. This means that each argument is stringified. To ensure that no special characters are used for binary data, the hash and the signature are encoded in ASCII using CrockfordBase32.
+%TODO: Add Link example
