Passive RFID tags consist of a microchip and antenna, activated by either a handheld or fixed RFID reader. These tags communicate by drawing power from the reader's signal.
Implementing RFID can boost productivity through automation. However, purchasing passive RFID readers and tags without proper planning may lead to unexpected challenges.
What are the challenges in choosing the right passive RFID tag?
RFID tags vary widely in shape, size, and performance characteristics. Selecting an unsuitable tag may result in poor performance.
What factors should you consider when choosing tags?
Types of Assets that need to be tagged with passive RFID tags
Different passive RFID tags are designed to be used with different types of materials. One type of RFID tag may work great on a paper file folder and become completely inoperable on a metal tool. Choosing the right tag is critical! Here are some examples of different passive RFID tags and where they are best used:
Metal Mount RFID Tags - These tags are specifically designed to be attached to or embedded in metallic surfaces. Standard RFID tags often have their performance severely degraded or become unreadable when placed on metal due to signal reflection and absorption. Metal mount tags incorporate shielding materials and antenna designs that counteract these effects, allowing for reliable reading.
Ceramic RFID Tags - Encased in durable ceramic housings, these tags offer excellent resistance to harsh environments, including high temperatures, chemicals, and physical abrasion. The ceramic material also provides good electrical insulation and can be designed to optimize RF performance in certain applications.
Hard Plastic RFID Tags - Encased in rigid plastic housings, these tags offer durability and protection against physical impact, moisture, and some chemicals. They come in various shapes and sizes and can be attached using screws, zip ties, or adhesives.
Epoxy RFID Tags - The RFID chip and antenna are embedded in a rugged epoxy resin. This provides protection against moisture, dust, and physical stress. They can come in various shapes and thicknesses.
Misc RFID Tags - Many other formats of RFID Tags can be found such as wristband, ear tags, bolt tags, as well as coin style RFID Tags.
RFID Labels - An RFID label is a flexible label with the RFID inlay embedded inside of it. These tags work well on paper and plastic. They are compatible with RFID printers and typically are the least expensive type of RFID tag available.
Size matters with passive RFID tags!
Passive RFID tags come in a variety of different sizes. From 4 inches wide all the way down to something smaller than your pinky nail. A good rule of thumb when it comes to RFID tags, the smaller the tag, the smaller the read range.
