Yes, I was also of the understanding that Bluechiip's sweet spot was storing high value tissue for longer term frozen storage situations needing robust identification so that lab people know what that vial contains The Bluechiip MEMS chip provides that identification number that is unique to the tissue stored in the vial. I don't understand how that relates in any way to the bulk shipment of vaccines that need to be kept in freezers when each vial does not need a unique number. A unique batch number maybe, but not a unique vial number.
