Well, it was going to happen, see link: http://news.scotsman.com/index.cfm?id=1588142006id=1588142006
"Pupils at a Scots primary school have become the first in the world to pay for their lunches by having their palms scanned rather than by handing over cash. Biometric technology which allows them to be identified through their hands' unique vein patterns has been introduced at Todholm Primary in Paisley."
Amey the company behind the palm scanner, have a Private Finance Initiative (PFI) programme in Scotland with Glasgow City Council, the largest education partnership in Europe. Amey worked in conjunction with Yarg Biometrics and Fujitsu to develop this biometric technology.
From Yarg Biometrics homepage : "Unlike fingerprint biometrics it cannot be linked to any criminal records database and civil liberties issues are therefore not affected"
And from the Fujitsu (now on the Wayback Machine here: http://web.archive.org/web/20061103111054/http://www.fel.fujitsu.com/home/v3__press.asp?prid=531) site, near the bottom of the article: "Biometric solutions will increasingly allow us to move towards a cashless society and this project is one of the first real examples in the UK of an innovative and truly practical biometric solution in operation. I fully expect this to be the first of many similar implementations across Europe" said Mike Nelson, General Manager, Fujitsu Europe Limited.
(Fujitsu is also providing a managed service in a fifteen-year contract for a Unity City Academy in East Middlesbrough. The Unity City Academy is a charitable trust. Members of the board of the Trust represent Amey plc, amongst others).
