RFID Tags

RFID tags bring the future of technology to today. Radio-frequency Identification(RFID) tags can be placed on almost any piece of clothing, cash, animals and even humans. Tags use electromagnetic fields to identify and track the desired object. Active tags are powered by a battery located inside the tag, and may operate over hundreds of meters away from the RFID reader. RFID tags have been expanding ever since their inception – they became especially popular when used in toll readers and assembly lines to track the product’s progress throughout the assembly line.

RFID tags commonly come in 3 different types of power modes – The tags can either be passive, active or battery assisted passive. RFID tags contain at least two parts that help the tag operate as needed. They contain an integrated circuit, to assist with the collection and storing of data. They also are equipped with a RF (Radio-frequency) signal, which gives the tag the power needed to operate, and an antenna to help receive and transmit signals. Unlike the common barcodes, RFID tags can be read or picked up by a reader, even if the tag is concealed or covered, making it the most attractable option to track important objects. RFID Tags have evolved over the years, going from simple toll route readers to being found in key cards in order to access a hotel room, and the technology behind the tags continues to grow and improve.

Technologies

With the technology of RFID tags improving, and becoming more popular and reliable, these tags can be found in your day-to-day activities. For example, if you have a toll reader in your car, the device that registers when your car enters and leaves the toll route is powered by RFID tags. Tags have become so compact, they make it hassle-free to place on objects that are always moving like cars, humans and animals. Tags are also found in clothing apparel stores; tags and labels are affixed to the commodities to ensure the product is not removed from the store without the proper removal of the tag first. Through the integrated circuit that is connected to an antenna, the RFID tag makes the securing of valuables extremely reliable and accurate. Modern readers are also built with memory, which can store the product’s electronic product code, and any other information that can be tracked by RFID readers.

It is important to understand the relationship between RFID reader and tags. The reader is responsible for communication with tags that are in its range and can perform multiple tasks such as keeping track of the tags location, assisting with inventory and encoding selected tags. Antennas also provide a critical service to both the tags and RFID reader. Antenna readers and tag readers will work in unison to help track the RFID tag. The antenna is simply powered by converting electrical currents into electromagnetic waves. Two common types of antennas are linear and circular-polarized antennas. Depending on the range you look to seek with your reader and RFID tag, both types of antennas will provide you with the range you need.

Applications

The evolution of RFID tags over the years has been remarkably large. They continue to become more accurate and reliable, which is important for anyone looking to track and collect data on important objects, like tracking the movements of an animal or tracking how far along your product is along the assembly line.

In retail, RFID tags are used to prevent theft of clothing articles, and other fashion accessories, like jewelry. The compact size of RFID tags makes it easy to place on virtually any objects, without having to worry about damaging the product you are tracking.

Here is a simple list of where you can find RFID technology being used: hotels, factories, assembly lines, shopping outlets, hospitals, the gym, public transportation, museums, libraries, schools and universities, tracking movements of animals, cars, humans, shipping logistics, travel documents, passports and airports. RFID tags reliability and their compact size have become an attractive option for many people looking to advance the simplicity of tracking important objects.
