NFC seems to be a great technology, but it must be improved to allow a long-range radio communication between devices. For this, you will need to make some investments, like buying Coaxicom products, mobile devices, chips and so on to build a stronger wireless connectivity technology.
No need to implant a chip--we all have a fingerprint. Several years ago I asked a technology expert at fingerprint-sensor manufacturer why credit-card companies didn't use a finger scanner at checkouts and point-of-sale terminals. He answered that it would cost more to install them and maintain the databases than to have enough reserve cash to cover fraud. So I guess we must continue to use PINs for a while longer.
John: I like your idea of the thumb print for ease of use. However, I wonder how the cost would compare to get something that is cheap enough to be installed all over the place, but safe enough to prevent somebody from lifting a finger print and using some simple techniques to transfer it onto something stuck on a perpetrator's finger. The 16-year-old minding the cash register probably won't be paying that close attention.
Rob: Any idea of how those eye scanner would work with those of use with glasses - especially with "more robust" perscriptions? At first look, I'm not a fan of anything but medical equipment shining in my eyes.
Good point, Jon. Actually, eye recognition may be easier ultimately than fingerprints. Yet I still think the current system with a PIN is very efficient. I'm not convinved a new system can improve on the current system to a degree that warrants a massive switch in technology. Paying at the register current takes just a few seconds. Do we need to trim if from 18 seconds to 12 seconds?
