Therefore, the market is calling for a convenient way to inquiry the authenticity of commodities. The phone has a carry-on convenience, if make the convenience of the mobile phone in conjunction with the two-dimensional code technology, it could make the phone two-dimensional security code has a broad market prospect. An anti-counterfeiting client is installed on the phone, through camera scanning commodity two-dimensional code, the client will be able to automatically connect the anti-counterfeiting server, then the server will give the anti-counterfeiting information of goods to client. In this way, Consumers does not require enter the serial number of goods for anti-counterfeiting, which will greatly facilitate check the authenticity of the goods. Further, since some of the characteristics of the two-dimensional code, for example, the high information storage capacity, will be able t
