PURPOSE: A legal product identification sheet coated with microcapsules and a method for confirming a legal product on the Internet are provided to enable a customer, a maker, and a legal product purchase information site to easily confirm the legal product sold to the customer through the Internet by using the legal product identification sheet. CONSTITUTION: A product ID number, a legal product ID barcode, and a legal product barcode number are printed on a color fixative part(1) of the legal product identification sheet made of paper or vinyl. The microcapsules(3,4) respectively containing desentizeing agents and adhesives are coated to a part excepting the part(6) that color fixative and a developer are reacted. If pressure is applied to the legal product ID barcode by using a pen, the microcapsules are destroyed and a color is represented by reacting the color fixative and the developer.
