RFID goes underwater for first time

The submersible read/write RFID tags don't require batteries and are completely water resistant.

By Staff -- Modern Materials Handling, 4/1/1999

To enhance process efficiencies and reduce contamination concerns, Escort Memory Systems has introduced the first submersible radio frequency identification (RFID) passive reader/writer.

"The application potential for this feature is particularly enormous," explains Stephen Crocker of Escort Memory Systems, "especially in the electronics and disc drive industry where the submersible read/write feature will enhance efficiencies."

In one application already in use, an RFID tag is attached to a cassette that houses media discs. When the cassettes are submerged in de-ionized water, the production data can be communicated from the underwater station's HM827-03 reader/writer to the 8mm RF tag. The longer the disc remains in the de-ionized water, the less risk of contamination. The tags do not require batteries, are water resistant, and can survive temperatures up to 464 deg F.
