Zeng Yingtao majors in wireless security and intelligent hardware. In spare time, he also studies the design of circuit board by himself. Some time ago, he and his friends used self-made transmitters to crack the anti-theft system of three cars, and could open the car door any time they wanted. They submitted a report of the holes to the car company and got over 10,000 yuan reward from the company. (Beijing News/Peng Ziyang) |
