Would that destroy the tags, or would they still remain operable under such conditions?

I’m going to say what I often do when answering this type of question: It depends.

If you take a raw passive tag or an active tag and expose it to 200 degrees Fahrenheit (93 degrees Celsius), the tag will not survive, as the solder used in most electronics equipment melts at around 182 degrees Fahrenheit (83 degrees Celsius). Tags that utilize common solder to connect the IC to the antenna would see the solder melt at 200 degrees, likely rendering the tag inoperable.

However, if the tag has been made using solder that melts at a higher temperature, the tag could survive that amount of heat. In fact, tags have been encased in a variety of materials to protect them against temperatures as high as 400 degrees Fahrenheit (204 degrees Celsius).

In addition, William Frick & Co. sells tags designed for high-impact and high-temperature environments. Different tags can withstand temperatures ranging from 300 degrees to 650 degrees Fahrenheit (149 degrees to 343 degrees Celsius) for up to two hours.
