Six Factors to Consider When Choosing the Appropriate UHF Tag

With particularly high frequencies, UHF RFID systems allow reading ranges of several meters. Tags, whose communication via the air interface is defined in accordance with ISO/IEC 18000-63 (EPC global Class 1 Gen 2), play a decisive role in this.

If the chosen tags are, however, not suitable for the application, if they are not sufficiently durable to withstand the process or if they do not deliver the necessary performance (in terms of reading range), the reading rate of the RFID system will be too low or the entire system may fail. It is therefore necessary to understand the technical demands and physical conditions of the relevant process in as much detail as possible.

These diverse conditions of different industries and applications generate a wide variety of tag-specific requirements, affecting aspects such as the design or the memory size. UHF RFID systems are being used for more applications all the time so the process of choosing the appropriate tag is becoming more and more complex.
