Hi - just found out last night, when I noticed DDs library book only had a bar code and not a date due back page, that they are doing biometric scanning in the school library. DD said that her thumb prints were taken last year but I received no parental consent form or information about it at all.
Apparently, whilst not illegal to take your child's thumb prints, the schools are advised by DCSF to involve parents and offer an opt out option. None of this was done at our school.
