Interesting technology. I don't think there's any doubt that something will replace the credit card but it is difficult to foresee what will tip the scales in favor of a specific technology. Certainly if NFC has already been five years in the making, there has been significant work on the communications side, plus also security. We'll have to wait and see if it is accepted in the marketplace.
I'm still a bit confused about how NFC is an advantage over our cards. It's really not much trouble to swipe a card at the point of sale. I would also think there are plenty of security issues. I guess I don't see the problem this technology would solve.
I, for one, would rather lose my smartphone. With all the passwords I have for the important apps, like banking, no one would be able to get into it. Of course, there are probably hackers out there that can troubleshoot my simple password, but it's better than losing my wallet and having someone be able to use my credit card immediately.
I have no doubt the e-wallet will be as ubiquitous as the smart phone is today is just a matter of time. One thing that stood out to me, though, was the comment about theft or losing a phone. I'm not sure what's more common--people losing their wallet or their smart phones? In the case of e-wallet based smart phones, I would think there is a ton of work to be done regarding security.
Great stuff! If I remember correctly, the Bluetooth specification was around for many years before it saw integration into popular consumer electronics. MEMS and Nanotechnology also had a fairly long incubation period before it got traction. Maybe now is the time for NFC to take off? It is so difficult to pick winners and losers in technology. Sometimes the most innovative winners need to wait until the rest of us catch up before their utility is discovered. It's up to the early adopters to keep plugging away and the manufactures to be prepared for delayed gratification. ...Just ask an "overnight" singing sensation how many years they spent singing in bars for tips before the became an international phenom...
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
