It is possible to track goods at that temperature without needing to thaw out tags to read them.
Cryogatt Systems introduced a solution in 2015 for the RFID tracking of cryopreservation specimens. That system employs HID‘s Piccolino passive 13.56 MHz high-frequency (HF) RFID tags, made using HID’s Vigo direct-bonding technology to attach each tag’s antenna and its chip, as well as Cryogatt’s reader and software platform. Both the readers and the tags are designed to operate at temperatures down to -321 degrees Fahrenheit (-196 degrees Celsius). The technology is being used by several cryopreservation laboratories that store human pathology samples, as well as blood and tissues, for genetic reference purposes (see Cryogatt Releases Cryogenics Solution).
In addition, Wake Forest Baptist Health is using passive UHF RFID tags on containers stored in cryogenic chambers. I am sure there are other examples.
