RFID-based Supermarket checkout pre-payment terminal ABSTRACT
Supermarket business conditions as an American born in the 20th century. Humen Town, Dongguan, Guangdong in 1990 gave birth to the first supermarkets in China - United States and good supermarkets, followed by domestic supermarkets have sprung up. After 1996, a group of world-class supermarkets (Carrefour, Wal-Mart, etc.) have entered China, meanwhile, have been appearing around the monomer or regional supermarket chains, such as Shanghai Hualian, Supply Chain Management such as supermarkets. Since then, the supermarket to enter the fast development track, the annual growth rate reached 70%.
RFID-based supermarket checkout pre-payment terminal as a meaningful pre-embedded electronic products, but also many supermarkets are now needed, can effectively solve the problem of the essential product line, is very powerful. In this design the system, using the Internet of Things technology (RFID radio frequency identification), the digital goods. System can speed up the checkout line speed, but also help customers effectively navigate the supermarket, the goods and quickly find the desired location. 毕业论文http://www.youerw.com/
