The system, which cost up approximately £1 million, was abandoned earlier this year because of escalating costs and lack of the functionality the college wanted. The college has been reluctant to answer questions, dubbing privacy campaigner and persistent questioner Pippa King 'vexatious,' and material relating to the trial has been vanishing off the Net. The law requiring parental consent for the use of biometrics in schools (for things like taking attendance and paying for meals) came into force last month. It seems it already needs to be updated."
