A school near Cambridge is planning to get rid of the normal school register and introduce a system where pupils sign in by scanning their fingertips.
Soon, if students at Impington Village College are absent or late, a text message or email will be automatically sent to their parents by computer.
The aim is to stop pupils skipping lessons and to help keep them safe by clocking them in - and out - of school.
The school also plans to use the technology for getting school meals.
This means pupils won't have to carry cash on them which could help reduce bullying.
The scanning system can also be used to issue library books, sign in for exams and quickly count pupils on school trips.
Every pupil and teacher at Impington Village College has already has their fingerprint information stored in a huge database, ready for the system which will be introduced soon.
It's thought it will be the first school in England to trial the system.
