Abstract: Duc to high cost of the current RFID technology application in the food tracking, it can't be used in low-cost industry. We proposed a Internet based low-cost solution for food tracking analysis using the two-dimensional code on the basis of Internet of things. By analyzing the two-dimensional code, middleware, mobile phones, computer terminals and other component parts in the Internet of things,we indicated the feasibility of the solution,of which the identificalion of two-dimensional code using the phone provides a great convenience. The final result is that the solution for traeking the food industry is currently a large number of applications.

Key words: Internet of things, Food tracking, RFID, 2-dimensional code
