3. Reading
The reader antenna is located inside the reader at the top. The back of the reader has a label
marked “READ HERE” which identifies the antenna area. While pressing down the Read button,
scan in a circular pattern while moving toward the head starting from the middle of the back.
Figure 2
The reason for this scanning pattern is that chip orientation plays a major role in the optimum
performance of the reader and reading distances. In Figure 3, below, CHIP(S) A, in a parallel
orientation to the antenna, will achieve its maximum reading distance towards the center of the
antenna or in parallel to either end of the antenna. CHIP(S) B, in the perpendicular orientation to
the antenna, will achieve its maximum read distance towards the outside edges of the antenna. It
is therefore recommended to move the antenna in a circular motion so that at some point you are
energizing the chip with a greater magnetic field making it easier to find the microchip.
