Abstract:
A method for providing product information including the steps of: (a) a user terminal receiving a product signal and confirming position information; (b) the user terminal transmitting the received signal and the position information to a main server; (c) the main server confirming whether or not a genuine signal corresponding to the received signal exists, and whether sale position information corresponding to the received position information exists; and (d) the main server transmitting the product information on the product to the user terminal when the corresponding genuine signal and the corresponding sale position information exist. According to the method, by providing a user with the product information and a provider with the purchase information, the counterfeiting of the product and the illegal distribution of the product can be prevented.

Abstract:
The present invention provides a touch tag having a conductivity pattern corresponding to a touch point of a capacitive touch panel. A capacitive touch tag according to the present invention includes: a substrate; a plurality of capacitive touch points which are formed on the substrate and are arranged at arbitrary positions on a virtual lattice corresponding to a touch input sector of a capacitive touch panel of a personal information device; a conductive wire for connecting the capacitive touch points; and an electric charge transfer unit for transferring electric charges to the capacitive touch points through the conductive wire. When the capacitive touch tag comes into contact with a smartphone, the capacitive touch points are recognized according to a predetermined rule, a result of the recognition is transmitted to a server, and information corresponding thereto is received and displayed.
