Parameters Affecting Reader Selection
Application Requirement:
The shape, size and functionality of a reader change according to the application of the RFID
system. Some of the common RFID systems are conveyor reading, dock door reading, forklift
reading, mobile reading etc.
Frequency Range:
A suitable reader, for a given application, can be selected to match the frequency range chosen
(LF, HF, UHF or Microwave). Multi-frequency readers can be chosen if the application requires
using both short as well as long read/write ranges.
Read/Write Range:
Read range is based on the frequency chosen, functionality of the tag and power of the reader.
Write range is the distance from which a reader can write tags. This range is usually 70% of read
range.
