RFID Introduction
Radio frequency identification, or RFID, is a generic term for technologies that use radio waves to
automatically identify individual items. The individual items identified/read by a RFID reader
contain a tag (also known as an electronic label or transponder). Unlike barcodes that must be read
by a beam passing over the barcode, RFID tags do not have to be in the line of sight of the reader
before the reader can collect the data from the tag but they do need to be within the established
reading range of the RFID-module.
See the “MX3-RFID Reference Guide” for further information and configuration.

Figure 8 RFID Tag Reading Ranges
Unlike barcode scanners that require line-of-sight before successfully reading a barcode, the RFID
reader does not require line-of-sight when searching for and reading tags. Pressing the RFID Read
button on the MX3-RFID starts a 360 degree search “beam” that stops at the limits of the scan
range of the RFID reader. The “beam” stops searching when the read timer expires.
Integrated Laser Scanner
The integrated laser barcode scanner can only read barcodes. The MX3-RFID cannot read barcode
labels and RFID labels at the same time. For example, the MX3-RFID can scan a barcode label
and when the good read/bad read/store data process is complete, it is then free to begin the process
of reading and storing the data from an RFID tag.
The RFID module can only read RFID tags.

COM3 is the integrated barcode scanner.
RFID and the MX3 Cradles
The MX3-RFID does not fit in the standard MX3 powered cradles. There is a passive vehicle
cradle available for the MX3-RFID that secures the device to the cradle only. See section titled
“Accessories”.
Main battery charging and host communication is not available directly through the passive
vehicle cradle. The passive vehicle cradle does not have LEDs or indicators. It does not accept DC
power connection. The MX3-RFID can be directly connected to external power through the power
jack located on the mobile device’s endcap. Host communication is available wirelessly while the
mobile device is secured in the passive vehicle cradle.
