Will we have issues reading information stored on a passive HF tag at temperatures as low as -80 degrees Celsius?

Most passive high-frequency (HF) and ultrahigh-frequency (UHF) tags can operate at -40 degrees Celsius (-40 degrees Fahrenheit). That's what you will find in the data sheets of most products. So manufacturers will not vouch that their products will work at lower temperatures. However, I suggest you purchase a few tags and a reader and test the tags, or work with a systems integrator to conduct a few tests. I know that Wake Forest Baptist Health is using passive UHF tags on containers kept in cryogenic chambers with temperatures as low as -196 degrees Celsius (-321 degrees Fahrenheit). So just because a tag is not guaranteed to work at -80 degrees doesn't mean it won't work at that temperature.
