Born in Cairo in 1945, Moreno was 29 when he patented the concept for a miniature electronic circuit board that could hold secure electronic data, an invention that would eventually earn him more than $130 million in royalties.
Moreno died in Paris but no details of his death have been released, Radio France Internationale reported Monday.
His patent became the foundation of so-called "smart cards," equipped with a miniature computer chip and now found around the world.
The technology also brought the SIM card used in cellphones.
A self-taught electronics engineer, Moreno set up a company, Innavatron, to exploit his smart card technology concept.
