+Barcode-Client

+The Barcode-Client is an interface to k4ever which can run on a dedicated
+computer/laptop.

+You'll need a user/password combination in k4ever, so go to k4ever's admin
+page and add a new user which is member of the *Plugin* group. Additionally
+you need an entry for the Barcode-Reader to appear on the settings page.
+All this can be accomplished by calling the *install.py* with the path
+to your k4ever django installation::
+
+	python install.py ../k4ever/
+
+At this point the Barcode-Client has no configuration file. All you have to do
+is to set three environment variables according to your setup::
+
+	export BARCODE_PLUGIN_USER=yourpluginuser
+	export BARCODE_PLUGIN_PASS=yourpluginpass
+	export BARCODE_PLUGIN_URL=https://path-to.your/api2/
+
+Afterwards you can start the Barcode-Client with *python freitagskasse.py*.
+
+If you have a Barcode-Scanner: Normally barcodescanners just act as a normal
+keyboard. Just let it type the barcodes into the Barcode-Client and everything
+should work.
+
+If you have a RFID-Reader: Most RFID-Cards have an ID which can be used to 
+authenticate against k4ever. A user needs to take this ID and put it in the
+authblob section. For an RFID_Reader to work with k4ever you can use the
+*rfid_keypresser.py*, which reads all input from the reader and translates
+them to X keypresses.
