Selecting the Right RFID Labels and Tags
Labels and tags come in hundreds of different shapes, sizes, colors, and materials. We understand that selecting the right labels and tags for your application and environment can be challenging. That’s where RFIDPros comes in, we have years of expertise in selecting the right RFID labels and tags for companies.
RFID Labels and Tags 101
Passive RFID tags can be as small as 0.3mm and don’t require batteries. Rather, they are powered by the radio signal of an RFID which “wakes them up” to request a reply. Readers can read passive RFID tags from a distance of about 20 feet. Semi-passive RFID tags contain a small battery that boosts that range. Passive tags are generally read-only, meaning the data they contain cannot be altered or written over.
Active RFID tags, on the other hand, are also called transponders because they contain a transmitter that is always “on.” A battery about the size of a coin powers active tags which allows them to communicate to a reader up to 100 feet away. They are usually larger and more expensive than passive RFID tags but can hold more data about the product and are commonly used for high-value asset tracking. Active RFID tags may be read-write, meaning data they contain can be written over.
Generally, we use passive UHF (902-928 MHz) RFID Class-1 Generation-2 (“Gen-2”) tags. “Class-1” refers to the functionality of the tag while “Gen-2” refers to the physical and logical standards of tag and the encompassing system. These standards are maintained by EPCglobal. “Gen-2” standards were adopted in December of 2004. Commonly known as 915, gen2 or UHF tags
Factors to Consider when Selecting RFID Labels and Tags
There are certain factors that will have an effect on what type of labels and tags you should use. The different types of tags one would use is determined by what item that is to be track tracked and the material of the tag will be determined by the environment that the tag will be used in. A few factors that affect RFID read performance include:
- Inlay size – a larger RFID inlay gives your longer read ranges.
- Reader type – handheld, fixed, and overhead readers often perform differently and serve different use cases.
- Material surface and environment – surface of the material, such as corrugate box, wood, glass, plastic, metal, etc, as well as how densely items are stacked, or what is contained within the boxes can affect the read range.
Although there are many options when it comes to RFID labels and tags, there are tags for all environments and applications. Whether you need labels and tags for warehousing, retail, manufacturing, or another industry entirely, RFIDPros can help find the right labels and tags for you.
