The I.D. Print ® system is a unique method of producing permanent, high-contrast black fingerprints without the mess of inks. Ideal for use at banks, retail establishments and in child identification programs, individuals simply press a finger onto an I.D. Print ® pad and then onto a special chemically treated card or label. Prints appear immediately, but leave no discoloration or residue on the fingers. The resultant prints dry instantly. The pads feature a unique ceramic insert, which prevents the inkless solution from evaporating over time and it assures that the inkless solution only coats the ridges of the fingers, producing perfect prints every time.
