Pupils at a school in Sunderland will be using an eye scanning security system, when their new £14m building opens in September.
The system will be used for ordering school dinners
The scanners will be used at the new Venerable Bede Church of England Aided School.
The technology will be used on pupils buying meals in the school canteen, and also in the library when children want to take out books.
It will secretly pick out poorer pupils who are entitled to free meals from those who have to pay, who will be charged in a separate account.
Ed Yates, head teacher of the 900-pupil school, said trained technicians will be able to scan up to 12 students per minute during lunchtime.
He said the technology was cost effective, safe, and backed by pupils.
Mr Yates said: "When we were doing the research to build the school of the future we looked at swipe cards or fingerprinting, but there are many civil liberties with the latter issue.
"This is the safest, most cost-effective system available. It has full safety approval from the US, and meets UK safety regulations."
He said he expected the system to be paying for itself in seven years' time.
