Foto Chamada (Photo Call)
Make a photo and have your classroom attendance list
Calling names in the classroom is an activity that takes up precious time in a class. Thinking about shortening this time is that was created the "Photo Call".

With this app you just take a photo of the students (asking everyone to look forward) and you're done: the app records the photo and recognizes all previously registered student faces. So within seconds you have the complete list of students in the class.
