These chemically treated thumbprint labels are for use with the I.D Print ® Inkless Fingerprinting System. Utilizing our unique I.D. Print ® system, the individual simply presses their finger into an I.D. Print inkless fingerprint pad. No residue or ink is left on the fingers. The individual then presses their finger onto one of the chemically-sensitized thumbprint labels. A permanent, black print develops and dries immediately on the label. Ideal for use at banks and retail establishments as a fraud deterrent. Each box includes 500 chemically-treated thumbprint labels.
