Operating the MC9090-G RFID 2 - 17

Reading RFID Tags
When in the RFID read mode, press the trigger and the mobile computer interrogates all of the Gen2
(configurable for Class 0 and Class 1) RFID tags within the radio frequency (RF) field of view. The mobile
computer captures data from each new tag found. When the trigger is released, the mobile computer stops
interrogating tags. In addition, RFID tag data can be stored on the mobile computer. Using the MC9090-G
RFID sample application, tags that are read display in the main RFID Tags window, see Figure 5-24 on page
5-28.
For more information about reading RFID tags and using MC9000-G RFID mobile computers, see RFID on
page 5-28.
To Read RFID Tags:
1. Ensure that an RFID tag reader enabled application is loaded on the mobile computer.
2. Aim the scan exit window at the tag.

RFID Tag Read
3. Position the mobile computer horizontally or vertically (as shown in Figure 2-19), depending on the
orientation of the tag.
4. Pull the trigger.
5. An audible beep sounds, by default, and the Indicator LED bar flashes green one time to indicate the tag
was decoded successfully.
6. Release the trigger.
NOTE For a successful tag read, the allowable read distance from the front of the mobile computer scan exit
window to the tag is 0.2 ft. - 10 ft. (0.061 m to 3.1 m). Reader motion horizontally and/or vertically may
enhance tag reading ability.
NOTE Tag decoding usually occurs instantaneously. The mobile computer repeats the steps required to read a
tag as long as the trigger remains pulled.
