Researchers from Texas A&M University, College Station, Texas, have developed a method of imprinting a hidden magnetic tag—encoded with authentication information—within manufactured hardware via metal AM. The process is expected to replace physical tags, like QR or barcodes, with imprinted tags to reduce counterfeiting.
