### GUI program:
129+
130+
This example uses the MAUI framework.
131+
132+
#### ReadDoc
133+
134+
After opening the device via the menu, the reading process, which can be
135+
started by pressing the Scan button or by automatic motion detection, is
136+
executed according to the subtasks set in the options panel.
137+
138+
The program performs the entire reading process in the background. It captures
139+
images with selected illuminations and analyzes the image data. If configured,
140+
it uses Carmen® ID Recognition Service (cloud authentication engine).
141+
In parallel, it reads ECard data after performing the related authentications.
142+
Finally, it compares the data with the GDS database and logs the data entry,
143+
if configured.
144+
145+
The read data is displayed in various representation forms. The display
146+
elements can be opened or closed by clicking on their headers.
