Biometric Payment

I hear that retailers like Wal-mart and Target are thinking about introducing biometric payment systems to reduce transaction costs. I think this is great news and would accelerate the process of adoption of biometric technology. One of my friends runs a dry cleaning business and is disgusted with the $1,000 he pays to credit card companies. That's a lot of money for a small business owner. 5% of total revenues is substantial. Greater adoption of biometric payment system will drive down the cost of biometric readers and thus making it more affordable to small business owners. We really need alternate payment systems. This "perpetual toll" to credit card companies has to stop. What would be really cool is availability of these biometric readers on personal computers. Imagine what such a thing would do to online retailing. Wal-mart and Target have taken the lead in the "offline" world. It would be great to see Amazon, Google, Dell and others get together for this initiative.
