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.
