The thumbprints are 'digitally transformed into electronic codes, which can then be recognised by a computer program'. The system was developed by Microsoft, and is being trialled elsewhere in the country. NO2ID condemned the system, saying it was appalling, and that 'It conditions children to hand over sensitive personal information.' The headmaster has defended the scheme, saying, 'We have researched this scheme thoroughly. It is a biometric recognition system and no image of a fingerprint is ever stored. It is a voluntary system. The thumbprint creates a mathematical template. All parents have been written to and we have told them what the system is all about. From the responses we have had there has been overwhelming support. We hold a lot of information about children because we are a school. This is no different.'
