RFID Reading

To read an RFID tag using a UHF Gen 2 RFID reader (e.g. Motorola Solutions 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 Solutions 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 begins to decrease; tag becomes
unreadable once Read Angle exceeds 90 degrees (see
through metal. The orientation of the reader (Reader Orientation) and the tag must be aligned to
improve read and writability (see
