To summarize, the strengths of Low Frequency RFID are the ability to read through materials with no reduction in performance, the ability to read in wet or dirty conditions, and a well defined, homogenous read zone. These are the main reasons that LF RFID is used for livestock, waste management and payment systems. A number of international standards exist, mainly for livestock but the ISO 18000-2 regulations attempt to define all standards for LF RFID by incorporating individual standards as appendices. Also, waste management standards are emerging with the EN14803 recommendations used throughout much of Europe.
