Title:
METHOD FOR PROVIDING RANDOM COMBINATION STATUS CODE FOR COMMODITY
Document Type and Number:
WIPO Patent Application WO/2017/133502
Kind Code:
A1
Abstract:
The present invention provides a method for providing a random combination status code for a commodity, comprising parts A and B provided on a commodity and corresponding circuit components. The parts A and B have particular joint surfaces, and their respective joint surfaces have conductive geometric patterns made of a conductive material; the combination of these patterns reflects the on/off of a circuit, thereby generating potential signals which record and transmit information by means of other circuit components. In this coding method, different storage statuses of a commodity can be distinguished according to status bit information sent by the commodity. The method can be widely used in commodity packaging, and can achieve good effects in managing commodity circulation, quality and safety.
