What Is A RFID Tag?

An RFID tag, or radio frequency identification tag, is a remarkable gadget. It is a wireless and “no contact” tag that relies on radio frequency waves in order to transfer data. They are incredibly helpful to those who use them because they are unlike other ID tags in that they have no “line of sight” requirement to communicate data. In other words, they don’t have to be seen in order to be read if the appropriate device is at work looking for the signals.

And though it is common to see an RFID tag using a permanent mount on something like a piece of costly equipment, you can find a stunning array of RFID tag options and uses. They include:

  • Key fobs
  • Wrist bands
  • Credential tags
  • Rearview mirror hang tags
  • Windshield tags
  • Standard hang tags
  • Standard tags
  • Extra-durable (industrial environment) tags
  • Metal-mount tags
  • High temperature tags
  • Indoor (all purpose) tags made of plastic, polyester and other materials, and much more

And while there are RFID tags in this wide range of designs and purposes, there are also the different properties that they feature. For example, you will find them in different frequencies, read ranges (such as being readable from 10 feet away), and functional in a diverse range of settings. Some are designed for industrial purposes, some for everyday use, and some for difficult settings, such as high temperature locations.

The Pros and Cons of RFID Tag Technologies

Apart from using them for their specific purposes, such as the wrist bands that are easily scanned by gates in amusement parks or other settings, RFID tags are great because they can work so well in such a wide array of settings. Unlike other tags that might become unseated and lost if near liquids or extremes of heat or cold, RFID tags remain firmly in place and well-performing. They also adhere easily to the widest pool of materials, including metals of all kinds.

The downside for some potential users is that their read ranges are not always expansive. Yet, that “con” is  negated when you realize that other ID tags are even less likely to deliver a comparable performance. As an example, a standard barcode ID tag might be unable to be read from a few feet away. That same tag, however, might easily send out the essential data if an RFID, and provide the user with the essential information and data.

And what about complaints of limited memory or data? That too is negated by the fact that any RFID tag can operate in a similar manner as a barcode, i.e. it can be associated with equipment and files that enhance the data available. For example, the RFID on a wrist band can open (if desired) into a screen of further data fields. Yes, it may only convey that initial, essential cue, and no further data, but that does not limit the data available upon scanning the code.

If you require some sort of data tagged items or equipment, RFID may be for you. At Express, a top manufacturing company providing barcode and labeling solutions for more than 30 years, you can find any labeling need or technology, including entirely customized RFID tags.
