Mario Cardullo

Mario Cardullo is an American inventor who received the first patent for a passive, read-write radio-frequency identification device, the kind of tag that returns stored data when a reader energises it and that later underlies tracking and access systems in many industries. He graduated in 1957 from the Polytechnic Institute of Brooklyn, now known as the New York University Tandon School of Engineering, and later earned his doctorate at George Mason University. The sources read for this entry give no birth year, so none is recorded here, and further detail on his career is left for a later depth pass.
