NFC lets devices share information at a distance of less than 4cm and at a maximum communications speed of 424kbps. The bidirectional capability makes it ideal for establishing connections with a simple touch. (Source: NFC Forum)
Nancy, non-electronic methods to handle credit card payments have been availablke since the mid 1960's. They are slower and quite a bit lewss convenient, but they work very well. I have used my card to purchase items at swap gatherings and at parking-lot sales, and that has been only slightly more difficult than using the slide-through credit card reader at the grocery store.
I agree that the electronic smartphone method of payment will bring about a whole new level of hacking and fraudulent billing. Within days of adoption of this technology somebody will come up with a receiver to record these near field transactions and figure out the code enough to duplicate the transaction, if nothing else. Of course those who wish to sell this new technology will say it can't be done, but what secure system has not been hacked already? And even if the link between the smartphone and the POS device is fairly secure, the link beond that is probably not going to be very secure, since it will be a cheap wireless interface.
WOW!, IF y'all think that modern computer file hacking is a problem today, then I'll bet you can't wait until these technologies & devices become ubiquitous througout the land! Then, you'll see hacking at its best!! ME? I'll stick to paper checks AND CREDIT cards only.
I wonder how affordable these models for mobile payment capability are for the small business owner or are they aimed at larger companies with an ability to invest in an expensive infrastructure? I own a company that used to make portable trail obstacles for horses. We would often go to remote locations with our products where we would loan the use of them for a trail competition and have a table set up for selling our products afterwards. A major frustration was that while our products were very well-received, people did not come to trail competitions with enough cash or with their checkbooks to purchase one - we lost the immediate sale opportunity due to their inability to pay. If a person had a means to buy on the site of the trail ride - problem solved. However, with our small profit margins, any of these mobile payment methods would have to be very affordable...
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
