Christmas 2007: a shopper looks longingly at a brightly packaged toy on a market stall. Are you sure it's the only one you've got? he asks the trader.
Yeah - and if you want it, you'd better buy it now. These antiques sell in minutes.
My kid would love it, the shopper sighs. OK. Do you take credit?
Sorry mate - cash only. The bank's down the street.
The shopper realises two other customers are looking interestedly over his shoulder.
No, hold on a minute, he says, pulling out a mobile. He slots a card into the phone, dials the number of a bank, and taps a few other keys.
Mondex? he asks, taking out the card and handing it over.
That'll do nicely. The trader smiles. The Gameboy's all yours.
