Why not use IR?

Clipping:
The Infrared data Association (IrDA) presented its vision for new wireless
point and pay financial transactions at a press conference in San Francisco,
Wednesday.
...
It said the point and pay demonstrations showed financial transactions with
credit, debit or checking account data being sent via IrDA interface from
devices like Palm handhelds or mobile phones to an IrDA enabled
point-of-sale (POS) terminal or a vending machine.
...
Users simply beam their financial information to make a payment and receive
a digital receipt.
...
With the two-way technology, the consumer not only provides the payment but
can also send or receive digital receipts and coupons or loyalty cards
providing the merchant with targeted one to one marketing opportunities.
