Picking up from this post on 37 signals around cash usability and the colour of Australian dollars being so much more effective as a design attribute than any figurehead in knowing how much cash you have in your wallet, I wonder if anyone is thinking around this area for debit/credit cards ?
I’m hopeless at managing money. Especially when I don’t know how much I have at any one time, which is er, just about all the time. With cash I knew and found it easier to budget. But with more purchases now made with plastic rather than cash, how could we develop a way to know how much we have "in our pocket" [or available on ‘credit’]? Surely this would be a fantastic service if a major bank managed to pull it off – you could create coloured bars or some other representation on cards that indicate
how much ‘money’ you have available everytime you use the card? Though any such development may mean that people become far more money conscious in knowing what they don’t have to spend and consequently there’d be less incentive for any bank to provide the service – unless it were a bank that created value from it’s customer service offering and charged accordingly for that – the co-op bank with its ethical consumer driven values would be idea wouldn’t it.
