Performance Expectations
Read range performance with our low frequency product line is gen-
erally dependent upon:
1. Transponder type or size
2. Read out antenna type or size
3. Possible electronic interference sources in the environment that
may be running on the same frequency or have harmonic
frequency noise.
The LF Micro Evaluation kit was designed for applications that need
compact, low-cost reader design with short read range.
