Electronically store data enabling RFID readers and antennas to identify and track objects. Each RFID tag has specific attributes that define its limitations physically, environmentally, and mechanically. When applied to a particular RFID system’s requirements, these limitations help narrow down the search to find the optimal tag. The seven attributes below should be considered when selecting an passive RFID tag.

Similar to the other parts of an RFID system, RFID tags should be tuned to the correct frequency range for the country in which they are deployed.

RFID tags are manufactured in different sizes and shapes to better accommodate for unique applications. Depending on the specific application and the amount of space on the object to be tagged, size can play a critical role in determining the ideal tag.  Some applications are hampered by the lack of available room on an object, such as tagging medical and surgical instruments.

The material and shape of the item to be tagged are two of the most important aspects to consider when determining the appropriate attachment method.

Some tags will work well with all-purpose adhesives and epoxy, while other tags will need to be adhered with rivets, screws, or welding equipment. Objects such as cardboard boxes typically will be tagged using general purpose adhesive, while metal pallets might require rivets or screws.
