DC's school is about to introduce this using finger-print technology i.e. you put money into an account and children have their finger scanned when they have a school dinner.
We haven't been given much info although there are workshops next week which I will be going to as DH is away. He is a IT professional and has a LOT of reservations about how such a system will work.
Do you have it in your school and, if so, what feedback can you give me about it?
Thanks
