DACTYSCAN84n IS A COMPACT AND FBI CERTIFIED
4-SLAP SCANNER IN FULL COMPLIANCE WITH THE
“10-PRINT CAPTURE SCANNER & SOFTWARE USER
GROUP REQUIREMENTS” SUITABLE FOR ALL
APPLICATIONS IN NEED OF 10 FINGERPRINTS FLAT
AND ROLLED ACQUISITION. MAIN APPLICATIONS ARE
VISA ISSUING, E-ID DOCUMENTS AND CRIMINAL
IDENTIFICATION.
DactyScan84n is a 3.2” x 3.0” live fingerprint scanner at 500 dpi, in
conformance with international standards, for acquiring 4-slap/2-thumbs fin-
gerprints as well as rolled fingerprints. Its footprint and low weight increase
mobility thus rendering Dactyscan84n suitable for desktop
applications as well as for integrated mobile solutions.
10 FINGERPRINTS
AND
ROLLED ACQUISITION
An ergonomic design combined with an easy-to-integrate SDK
architecture turning DactyScan84n into the perfect choice for integrators
and solution providers. Dactyscan84n integrates a 12 LED graphical user
interface eliminating the necessity for skilled operators thus increasing
workflow efficiency. No silicon pad or heated glass platen is used
resulting high reliability and low maintenance costs.
FBI CERTIFIED
DactyScan84n is suitable for all applications requiring 4-slap
fingerprint acquisition including rolled fingerprints according to FBI
IAFIS-IQS quality. Dactyscan84n processes fingerprints faster, more
simply and thanks to Green Bit unique software features more reliably
compared to the traditional ink method eliminating the need for skilled
USER INTERFACE operators.
