Are Any Tiny RFID Tags Able to Withstand High Temperatures?

Posted By RFID Journal, 11.20.2012
We seek a solution to track our storage items (kitchen utensils, chinaware, glasses and so forth) efficiently, and would like to use RFID labels or tags. However, we face some limitations: The labels or tags need to be waterproof and steam-proof, since all items will be washed frequently under high temperatures, and they also need to be tiny and capable of being affixed to plates, glasses and other items, either invisibly or at least without changing those objects' appearance. As a professional in this area, can you please provide some recommendations and options? Thank you very much!

There are tags designed for tracking medical devices that are small and can withstand high temperatures. The Pico X II tag, from Xerafy, measures 0.7 inch by 0.43 inch by 0.19 inch and can withstand temperatures ranging from -40 degrees to +150 degrees Celsius (-40 degrees to +302 degrees Fahrenheit). And the company's Dash-On XS tag, which measures 0.48 inch by 0.12 inch by 0.09 inch, can withstand similar temperatures. These tags are likely too large for use with eating utensils, however. There are even smaller tags that can be inserted into a cavity drilled into metal, which can then be filled with epoxy, but the read range on such tags is only a few inches, which might not help you very much.
