RFID Tag meet Broadband Video

I just bought a do-it-yourself home RFID tag system called TouchaTag by Alcatel-Lucent.  RFID stands for radio frequency identification device.   Automatic toll passes, such as EZPass, use RFID technology.   Libraries use RFID tags for book check-out.  My dog has an embedded RFID tag to identify him if he is lost.  Touchatag enables you to create your own Internet of Things by attaching RFID sticker tags to everyday objects and linking these tags to computer commands and websites.  Pass the tag over a reader, and the command(s) or website is activated.

Touchatag's starter kit provides 10 RFID sticker "tags" and a USB connectible tag reader.   Here's a very simple example that I created.   I associated a tag to trigger and log-in to my daughter's math homework site.  She attached the RFID sticker to her homework folder.  To start her math homework online, she just places her folder next to the RFID sticker reader and her homework site appears on the screen.   At first, I didn't think this would be very useful, but we've grown accustomed to just "touching" the folder to begin her homework.

What does this have to do with broadband TV?   I use the same process to access various broadband TV shows, sites, or genres.   For example, if you want to watch The Office or browse what's new on the Action & Adventure channel on Hulu, just define tags and place these on a card with a picture of an office or a DVD case.   Simply touch the tag to the reader and your show appears on your broadband connected TV.

I've just started experimenting, but I can see this becoming more useful when companies introduce tags whose actions can be activated at a distance from a stationary readers or tags than can be pressed to activate.  Some phones, for example, serve as tag readers today.   NFC (near field communication) turns your phone into a an RFID tag reader so that you can activate your favorite TV on your broadband connected TV using your phone.  Here's an example using an iPhone with RFID/NFC.

At some point in the future when tags activate lights, televisions, and stereos, one can press a tag and activate a "mood" via the use of RFID and WIFI in the house.  But, now I'm getting ahead of myself...

  2. If an animal gets loose, RFID technology can help the rancher track it down. This technology can also be used in automated feeding of the animals, weighing of the herd and disease management, all things that had to be done manually in the past.https://www.farmpally.com/rfid-technology-in-agriculture/

  3. We all living around the technology and smart devices many advanced technologies are used by every industry, RFID technology is one of that which is trending between the peoples. RFID is an acronym for “radio-frequency identification” and refers to a technology whereby digital data encoded in RFID tags or smart labels (defined below) are captured by a reader via radio waves. We provide RFID positioning system at an affordable price.
