Each individual’s finger prints are unique. The biometric cashless system will store only a section of the print as a unique number and not as an image. Each student or staff member will have a unique number stored on a central server. This is done by scanning the finger with a non-invasive electronic scanner, which passes light over the finger. The same scanner will be installed in the scanner machines where pupils check their refectory balance and at the tills where they get their food. A print will be stored numerically; the system does not store the image. The stored co-ordinates are only of use in matching part of the individuals print and cannot be used for the purpose of reconstructing a print. The numeric references are held on a secure server. Access to this database is given only by the school and then only to those who are required to administer the system.
