Most of RFID tags can not be stored and read under ultra-low temperature and deep low temperature environment. The management of biological samples also mostly relies on manual or two-dimensional code, and manual management is prone to errors, and two-dimensional code inventory needs to be scanned each by each, which is also very troublesome. For this reason, RTEC, one of the leading RFID tag companies has developed low temperature RFID tags that can be stored in liquid nitrogen and can be read at -196°C. This RFID cryopreservation tag can be read immediately after removal from liquid nitrogen. This RFID Low temperature tag is very small, which can be embedded in the bottom of the frozen storage tube.
