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.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
