CGTN talked to Prof. Rui Martins recently about casino chips. 

Prof. Martins is the vice-rector for global affairs at the University of Macao and director of the school's AMSV lab. AMSV stands for analogue and mixed signal VLSI (very large-scale integration). It studies the interface of signals between the digital world and physical world. The lab is one of China's State Key Labs tasked with advancing the country's science and technology standing.  

Prof. Martins and his team's recent creations include chips that allow one smartphone to charge the battery of another wirelessly, research that could put the university, and China, on the map in the field of electronics.
