☆ Check whether the frequency point setting of the reader is correct.
☆ Check whether the RF output power of the reader is small, and adjust the
output power if necessary.
☆ Check whether the polarization direction of the tag and the antenna matches.
If the antenna is vertically polarized, the tag should be placed vertically.
☆ Check whether the tag is a special tag. If the tag is an anti-metal tag, it needs
to be placed on the metal surface to achieve the best reading effect.
☆ Check whether the RF cable connector connecting the reader and the antenna
is loose.
