Impact on the transmission window by metal

In general, the following points should be considered when mounting RFID components:
● Direct mounting on metal is allowed only in the case of specially approved transponders.
● Flush-mounting of the components in metal reduces the field data; a test is
● When working inside the transmission window, it should be ensured that no metal rail (or
