Hiccups in a Cashless Society

jchaw sent us a story thats running over on CNN and talks about hiccups with Singapore's Cashless System which apparently messed up 4500 transactions and caused a quarter of a million dollars to be lost in the system. Kinda creapy- as we become more and more reliant on credit cards, debit cards, and ATM cards, the chances of bugs popping up increases.
