I'd love to see Apple do a watch, or a clip-on to a watch that enabled financial transactions as a substitute for cash.

It'd probably need some type of rfid, and the merchant some type of biometric, otherwise if someone saw the watch, they might be tempted to steal.

Why wait for Apple to do it?

A friend of mine is doing this, but on a card, not a watch:

They'll be going live within the next couple of months, keep an eye out for something called the real X card.

Trust, reliability, scale, innovation, reach, longevity, security, efficiency: that's what will separate the men from the boys!

something like a credit or eftpos card perhaps? :)

Something faster, and with zero (or very close to zero) transaction fees. Also, something that people aren't afraid to lose (like a credit card), and which is pointless to steal, and where fraud is reduced. Something with a screen to show balances and other info.
