Ricky uses a face scanning machine
Face and fingerprint scanners are being used in some schools to keep track on their pupils for things like registration and library books.
More and more schools are switching on to technology in the classroom, but is your school?
Do you have things like scanners, or is it all still paper and pencils that keeps your school going?
And if there isn't much technology in your school, what would you like to see introduced to make things better?

Leila, 11, West Sussex, England
