How Many Types of RFID Tags Are There?
How many types of RFID tags are there? There are several ways to classify RFID tags, but the main categories are passive, active, and battery-assisted passive tags, while LF, HF, and UHF describe operating frequency. UHF passive tags, also called RAIN RFID tags, are the most broadly implemented for industrial identification and supply-chain applications. That distinction is important. When engineers discuss “RFID tag types,” they may be talking about power source , frequency , physical construction , or application . These are different classification systems, and mixing them together is one of the easiest ways to make an RFID specification confusing. For example, a tag can be: Passive + UHF + on-metal + EPC Gen2 Those four descriptions are not competing categories. They describe different characteristics of the same tag. RFID Tags Are Mainly Classified in Two Ways The first classification concerns how the tag gets power . The second concerns which radio frequency it uses . The ...
