Re: Why have "cards" at all?

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.

These days I carry cash and use credit cards infrequently.  I can get a receipt if I need one.

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.

Let's go whole-hog - have an RFID chip implanted subcutaneously.  We already do it for our pets; such a chip can be your PIN, and absolute proof of identity.

Not sure how that works with glasses, Jack. I still think the use of the PIN is very safe and very simple. I'm not convinced that other forms of recognition really improve much on that.

Great article Sylvie!

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?

Why can't I just go up to the checkout, choose VISA on the display, and have the terminal scan my fingerprint?  For extra security I might have to key in a PIN. I haven't yet misplaced my thumb.
