RFID was once star of the hype cycle. Is it only technology for the sake of technology? Can it replace barcode?

any thoughts?

Read-write RFID tags used as checklist in automobile manufacturing process, now that's intelligent , creative, and purposeful use of the technology. Impressive.

Sadly, I cannot say the same thing for the wiz-bang Coke machine. I find the following truly puzzling:

"By employing RFID, Freestyle is able to perform functions unlike any previous beverage machine. Using RFID tags and a permanent reader, it immediately "knows" each cartridge and recalls when it was plugged in. It can track the amount of liquid dispensed and can predict usage rates and inventory needs."

Really? Without RFID there was no way to know this? Call me when I can order and pay for my drink with my phone via NFC :-)

Pigeon holed technologuies

You're exactly right.  A great idea can quickly get minimized if it's too closely related to something that it just replaces.  As opposed to RFID which is starting to be used in these other applications.  There are so many other opportunities for RFID to be used.  To me I love to see it used in agricultural applications.

It's great to see companies finally recognizing the unique advantages of RFID and applying the technology to new applications as opposed to be stuck trying to use it as a bigger/better substitute for bar codes. This illustrates the larger problem that often impedes technology progress: Being pigeonholed as a replacement for something that still works as opposed to exploring what's possible thanks to new innovations.

Nice piece, Chuck.

RFID and Location

Great article.  In my previous position, I was looking into industrial strength read-write RFID tags as a means of identifying the serial number and specs of large AC motors that were installed and noting if/when changes occurred.  Unfortunately, I was unable to use a single reader that would tell me the location of the tag (i.e, whether it was motor 1, 2, 3 or 4).  It could tell me the 4 serial numbers that were in use, but not where, which at that time was an important issue in that we wanted no human involvement in the system.

Internet of things

I suspect the internet of things will have a huge impact on society in general.  Imagine if the changes that have been noted for manufacturing are carried over to consumers.  In the case of my car, now it needs an oil change or perhaps the operating conditions need to be monitoried by something like onstar.  Or toll booths need to collect data on what just went by.  Law enforcement is going to experience a big change once the accessibility of data is established.  

Lots of changes are coming in our increasingly digital civilization.

Great Overview!
williamlweaver   10/12/2011 10:28:39 AM
Thanks for such a great overview of the RFID sector. I've been teaching a college course in technology for the last 13 years that centers around Barcode technology, its component electronics, software and utility in supply chain management. We have been discussing the future of RFID each year and watching its progress as a barcode "Upgrade". You are right on target...  The Barcode is alive and well and serving its purpose admirably. It's the special applications that RFID can do that Barcodes can't that make the technology so exciting. I'm looking forward to the upcoming Internet of Things -- it has the chance to become a huge source of employment for our graduates.

Automotive RFID

Nice article, Chuck.

Another cool RFID application is in automotive production. They're using read-write tags to keep track of what has happened as a vehicle moves through production. The tag is programmed with all of the specific requirements for the individual vehicle (paint color, features, type of tires, etc.). As the vehicle moves through production the tag is read to see what it needs. As these items are put into the vehicle, they are checked off on  the tag. This cuts down on mistakes considerably while supporting mass customization.

From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
