RFID Position Markers work with semi-passive RFID tags.
November 20, 2008 -
Used as alternative to RTLS for determining exact locations of long-range, semi-passive RFID tags, Models 491013 and 491014 position markers are placed near antenna, and as tag passes antenna, identification data from position marker is downloaded onto tag. Markers offer 16 bits of programmable position data, 125 KHz frequency, AM modulation, 4 LED indicators, as well as user interface for programming loop ID, setting loop current range, and loop diagnosis.
Toronto, Canada - GAO RFID Inc. (www.GAORFID.com) now provides advanced RFID position markers (GAO 491013 and GAO 491014). The RFID Position Marker series are used to determine exact locations of long-range, semi-passive RFID tags (GAO 137003, GAO 137004).
The Position Marker is typically positioned near the induction loop (antenna) and remains maintenance-free after setting the original parameters. As the tag passes the induction loop connected to the Position Marker, it is "woken up" and identification data from the Position Marker is downloaded onto the tag. Depending on the type of tag, current as well as previous IDs and the relative time of passage over the loop are either repeatedly broadcasted or can be read from the tag by a RFID reader (GAO 227004) at a later time. This intelligent ability to control the inductive field limits enables it to distinguish lanes and recognize directions.
"By taking advantage of semi-passive technology these position markers offer benefits similar to RTLS at a very reasonable cost," says Dr. Frank Gao, CEO of GAO Group.
