By the way, the Walmart thing is about costs, Visa has different costs for card swipe vs. pin based, thats the issue on that. The vendors are already getting around it with software, note when you swipe a card at some terminals it will ask you for a pin like it or not? Thats why, the interchange fees the visa system is charging.
There is a new product that allows a cc swipe from a floppy drive.
You get the hardware, register it with an aquirer, swipe the cc and the hardware has a chip to verify, process and then send the transaction via software to the cc network. The network can't tell the difference between a card terminal and a home PC.
The inventors are looking for a company with the capitol to give away the HW, then they will clean up on the software and fees to send the transaction.
I think this technology has a better shot at making it into homes than biometrics. I got a laser hand authentication system for a time clock and it was $$$$$$.
