The orientation of the reader antenna to the ID tag affects the range and ability to
read. For the best reading performance a circular motion is recommended.
3.2. From RF Sources And Metal Objects

order to read ID signals from the ID tags. Computer terminals video screens and
metal can reduce the read range of the reader.
