Great story from Merlin Johns blog http://www.agent4change.net/innovation/innovation/977-oyster-on-menu-for-lewisham-cashless-school-dining-.html
about how Lewisham are using Oyster card technology in Schools for cashless catering . Great story and great use of widely avaiable technology the next step especially in many non oyster areas will be use of NFC enabled devices mobile phones etc. The idea of the wallet on the phone is more clever than that because you can sub divde your wallet . so for example some for spending on specific things and others for more general expenses . But well done to Tom and his team and a good story Merlin.
