Farbo Uniforms is developing garment-tracking solutions based on a novel passive UHF RFID tag with an antenna made of metalized thread sewn into a garment.
Aug 28, 2015—Farbo Uniforms, a Hong Kong uniform provider, reports that it is developing garment-tracking solutions based on a novel passive ultrahigh-frequency (UHF) EPC Gen 2 RFID tag with an antenna made of metalized thread. The tag, known as the CS8200, was developed by Convergence Systems Ltd. (CSL) and is unique in that the antenna is added after the tag is applied to a garment.
There are other tags on the market that use thin wires for antennas, but these are part of the tag, encased in protective material and applied to the garment. The CS8200 tag is different in that it includes two metal pads, one on each side. The thread—which creates a dipole tag antenna—is added after a tag is placed on a garment, with metalized thread stitched into each pad, as well as a garment or other cloth item, in either a straight or wave pattern. The tag is then sewn to the garment, or affixed via heat-sealed tape. The tag itself measures 17 millimeters by 34 millimeters by 1.4 millimeters (0.7 inch by 1.3 inches by 0.06 inch). The total length of the tag’s thread antenna can be 60 millimeters, 100 millimeters or 140 millimeters (2.4 inches, 3.9 inches or 5.5 inches), depending on the desired read range.
