Can you please provide some examples?
HID Global offers its Brick Tag Ceramic ultrahigh-frequency (UHF) transponders, which it says are designed to withstand environments requiring metal applications while complying with evolving industry standards. The tags feature the ISO-18000-6C-compliant Alien Technology Higgs-3 RFID chip with 512 bits of memory, and can be read from and written to a distance of up to 3.3 feet (1 meter). The tags have a hard ceramic exterior shield to protect them from exposure to extreme conditions and are IP67-rated (see HID Global Intros Ceramic Brick and Slimflex On-Metal Tags).
RFID tag maker Omni-ID offers a line of high-temperature passive UHF RFID tags, encased in ceramic, for use in environments that reach 225 degrees Celsius (437 degrees Fahrenheit). The tags are intended to enable manufacturers, oil producers, hospitals and other companies to employ RFID in traditionally unfriendly environments in which extreme heat is used. The high-temperature tag family consists of the new Fit 100, as well as the Fit 210 and Fit 400—high-temperature versions of the company's existing Fit 200 and 400P models (see New Omni-ID Passive UHF Tags Endure 225 Degrees Celsius).
Japanese electronics company Kyocera recently released an ultra-small ceramic tag designed for tracking small tools—those used during surgery or aircraft assembly, or at nuclear sites. The tag measures just 5 millimeters by 2 millimeters by 1.5 millimeters (0.2 inch by 0.08 inch by 0.06 inch). The company is offering samples to potential customers in multiple industries across Japan, North America and Europe (see New On-Metal UHF Tag Measures Just 5 Millimeters in Length).
Earlier this year, Murata Manufacturing introduced a new on-metal tag to ease the use of passive UHF RFID tracking on metallic items. The small tag is designed predominantly for use in managing surgical tools, but could also work with other tools or small metallic products (see Murata Developing Small On-Metal Tag for Surgical or Industrial Tool Tracking). And Technologies ROI offers heat-resistant metal tags that can be welded to metal objects (see Armored-RFID Tag Loves to Get Hammered).
All of these companies will be exhibiting at this year's RFID Journal LIVE! event, the world's largest RFID conference and exposition, which will be held on Apr. 2-4, in Phoenix, Ariz.
