Regula Game-Changers in Comparator Development

LED illuminators

The transition to LED light sources (including UV illuminators) instead of analog lamps has advanced the process of document examination with cutting-edge technologies.

Creation of Information Reference System (IRS):

The world’s largest digital collection of identity documents, visas, banknotes, coins, and vehicle documents enhances forensic examination by providing experts with detailed descriptions to compare an examined object to its reference standard. As a weekly updated database, the IRS now comprises over 11,880 documents from 220 countries and territories.

Embedded RFID chip readers:

With an RFID chip reading module inside the device, Regula comparators enable complete verification of electronic identity documents by checking the chip data and integrity.

Digital image capture:

The use of digital cameras has revolutionized the forensic examination of documents, banknotes, etc. Any image of a physical object captured with a comparator can be easily processed through scaling, light filtering, cropping, and other techniques, which helps streamline the analysis and report generation.

Anti-Stokes fluorescence detection:

Equipping devices with a specific light source (high-intensity IR light at 970-990 nm) allows for the examination of security features in documents and banknotes printed with Anti-Stokes ink.

Hybrid document examination:

The technical capabilities of devices combined with Regula Document Reader SDK allow for the physical and digital examination of identity documents, including the validation of security features and data obtained from barcodes and RFID chips.

Hyperspectral imaging:

The presence of a hyperspectral analysis module* facilitates non-destructive examination of handwritten and printed documents, banknotes, historical records, etc., enabling the detection of fraudulent alterations, identification of the initial content, and determination of a document’s age.

Noiseless devices in a durable design:

Engineering innovations have eliminated the need for cooling fans in Regula equipment, extending its operating life. This also ensures that there is no background noise during examination, and prevents dust from accumulating on the internal parts of the comparators.

3D visualization:

Building a high-resolution 3D model of a document or banknote fragment allows for examination of surface relief, detection of printing methods, and analysis of overlapping objects, such as signatures and stamps, including measuring the height and depth of the printing layer.
