The most basic delivery of a RFID tag is the Depending on the application, RFID tags come in a variety of shapes and sizes. When we're referring to encasement, we're talking about the physical form factor of the RFID tag. If you'd like to know more about what affects read range in an RFID system, please see our post about factors that affect RFID read range. In short, a dual dipole RFID tag will be readable from more orientations, where as a single dipole RFID tag may need to be read in a more controlled orientation. An additional factor regarding tag antennas that affects how they act in an RFID system is the number of dipoles the tag contains. On metal RFID tags, which have special backings, leverage their metallic surroundings to harness reflected energy and increase read ranges. Background insensitive tags have foam material around the antenna so that the they can be placed both on and off metal. However, the properties of metal can be used as an advantage if the correct tag is used. Water and metal absorb and reflect RF energy respectively and, in doing so, may decrease an RFID system's performance (read ranges and read rates). Additionally, RF antennas can be strongly influenced by their surrounding environment.
Small RFID tags contain small antennas which leads to shorter read ranges, while large RFID tags (with larger antennas) will have longer read ranges. For more information, check out our blog post on chip memory in UHF RFID tags.įor general purposes, the size of the tag's internal antenna will be a strong indicator of the tag's read range. However, some tags are more expensive because they have extended user memory to store more information on the RFID tag. This is enough space to store 24 hexadecimal characters (0-9, A-F).
UHF RFID TAGS ISO
ISO 18000-6C) and use 96 bits of memory to store the EPC (Electronic Product Code).
Generally speaking, most UHF RFID tags adhere to the Class 1 Generation 2 standard ( Some IC types can store more information than others. The IC (Integrated Circuit) is the brain of the RFID tag and stores the unique information on the tag. Three Important Component Differences Among RFID Tags: 1. When selecting the right RFID tag for your system, we have identified some core differences between UHF tags. can make finding the best tag for the job a little daunting. Form factors, price ranges, read ranges,Īttachment methods, etc. Of all these components, the RFID tag varies the most and significantly impacts the overall success of the system. In every UHF RFID system, there are four basic components: These systems are known for generating long read ranges relative to other operating frequencies. This post will focus on ultra high frequency, or UHF, systems (433 MHz, 860-960 MHz). In physics terms, frequency is the number of complete wave cycles passing a point in a second. RFID comes in many different flavors, but an easy entry point from which to grasp RFID technology is to first RFID, or Radio Frequency Identification, can be a confusing field for those starting to learn about the technology.
