Introduction
Use Tag Locator to detect the location of a tag. By providing the TagID of an item, this application can find the 
relative position of the tag with respect to the mobile computer. Move the mobile computer back and forth to obtain 
the location of the tag as indicated by the beep frequency and a vertical progress bar showing the relative position 
of the tag.
The Tag Locator application requires the following components/DLLs on the device:
•RFIDAPI32.dll (Version 5.1.15 or higher)
