2.7.1 RFID Reading
To read an RFID tag using a UHF Gen 2 RFID reader (e.g. Motorola’s MC9090-G), open an
appropriate RFID read application, point the RFID reader at the tag and activate the reader's RFID
antenna (e.g. pull Motorola’s MC9090-G scanning trigger). RFID reader must be within 1 foot from
tag in order to read.
Two variables, Read Angle and Reader Orientation, aid in the distance needed to read and write to
the RFID Tag. Read distance is independent of Tag Angle, but the reader should be as close to
perpendicular to the tag as possible (Read Angle).
As Read Angle increases past 60 degrees, read distance will begin to decrease; tag will become
unreadable once Read Angle exceeds 90 degrees (see Figure 2-64 and Figure 2-66). RFID tag
cannot be read through metal. The orientation of the reader (Reader Orientation) and the tag must
be aligned to improve read and writability (see Figure 2-70).
