Seattle RFID chip designer Impinj is hailing the reliability of its UHF (ultra high frequency) supply chain technology at a health care industry summit in Washington D.C.

Impinj is aiming the RFID tags and readers at the pharmaceutical industry to identify and track prescription drugs. But the industry so far had been leaning toward high frequency (HF) chips for speed and accuracy. Whether that technology is adopted could play a big role in Impinj's future.

Impinj said this morning its technology performed with 100 percent reliability during a live demonstration.The company demonstrated reading 600 tags per minute on bottles containing liquids, gel caps, solids and powder. The tags were made by Owens-Illinois with Impinj chips inside.
