Technology Advancement of RFID Tag

The continued growth and acceptance of new technologies are fuel by technological advancements. These advancements can provide the following advantages:
· Make existing applications easier to use
· Offer more functionality
· Drive deployment costs down
Due to technological advancement, it has open the door for the new applications that were not imaginable or possible before. . In the following section, we explore some of the more significant technological advancements that are under development today.
The newest and most advance RFID Tag is the one which being created by Hitachi last 4 months. These RFID chips just measured 0.05 x 0.05 millimeters. The previous record-holder, the Hitachi mu-chip, is just 0.4 x 0.4 millimeters. Take a look at the size of the mu-chip RFID tag on a human fingertip. Tiny miracles of miniaturization (mu-chip) only appear like a normal powder when we put on our fingertips.
Now, compare that with the new RFID tags. The Hitachi "powder type" tags are some sixty times smaller. With just a measurement of 0.05 x 0.05 millimeters, these powder tags are even capable to prevent a theft from entering your house!
Moreover to amaze everyone, this new RFID chips have a 128-bit ROM for storing a unique 38 digit number, like their predecessor. To achieve the new and smaller size of this RFID powder, Hitachi used semiconductor miniaturization technology and electron beams to write data on the chip substrates.
Previous Hitachi's mu-chips are already in production; they were used to prevent ticket forgery at last year's Aichi international technology exposition. On the other hand, RFID 'powder' is so much smaller that it can easily be incorporated into thin paper, like that used in paper currency and gift certificates. These tiny RFID tags could be worked into any product or condition. It can even be combined with RFID readers built into doorways, these will make it possible for the theft. According to the manufacturer, if this chip needs an external antenna, the attached antenna would be a tiny ribbon of wire more narrow than a human hair and only a fraction of an inch long.
How far away could you be, and still read the information from this "powder RFID”? The mu-chip previously invented is readable from a distance of 25 centimeters (about ten inches) with an external antenna. . This doesn't sound like much, but it's certainly enough to read people going through doorways, for example.
In addition, these devices could also be used to identify and track people. For example, suppose you participated in some sort of protest or other organized activity. If police agencies sprinkled these tags around, every individual could be tracked and later identified at leisure, with powerful enough tag scanners. Seriously breathtaking invention ever!
Furthermore, to put it in the context of popular culture, see the picture below, which was taken from the 1996 movie Mission Impossible. This pretty clunky-looking tag was being used by one detective whose places a tracking tag on the shoulder of a computer programmer during the investigation.
With RFID readers and tags becoming all the rage in safety compliance, no one can quite deny the fact that the RFID technology has become one of the most advanced and demanded gizmos for anything involving equipment tracking. After becoming all the rage a few years ago, now RFID technology is undeniably one of the greatest technological contributions to the industry. So now the question becomes, is there anything better than this?
