6.4 tAg-to-AntennA orientAtion
Tags should always be presented face on to the external antenna surface (i.e. with the coils of the reader antenna and
the tag parallel). This is the position for optimum coupling (power transfer) between the antenna and the tag, and
hence gives maximum read range. Tags may still work at an angle depending upon the distance between the tag and
the external antenna.
