The Digit 10 system is the cleanest fingerprinting method on the market. Our unique inkless formulation produces permanent black prints on any fingerprint card. Just 40 seconds after rolling, permanent black prints that meet all FBI requirements develop. Special high-contrast cards are also available for highest-quality impressions best for scanning into AFIS. Each developer sheet processes up to 100 individual cards and the special fingerprint pad yields up to 10,000 individual prints. When not in use, store the kit in its custom carrying case (included) for easy and safe transport.
