Topaz SigLite LCD 4x3 signature pad

The Topaz SigLite LCD 4x3 is a signature capture pad built for point-of-sale and office environments that need reliable electronic signing. It uses a pressure sensor with a passive stylus on a 4.4 by 2.5 inch signing surface. Dual Serial and USB interfaces connect to a wide range of host systems. The backlit transflective LCD shows electronic ink under the pen tip during signing.

Thermals noise and power draw

The unit draws power directly from the USB or serial connection, so no external supply is required and heat output is negligible in daily use. With no moving parts or active cooling, operation is completely silent at the counter. The 2.00 lb weight and compact 2.10 by 7.20 by 6.60 inch footprint keep desk clutter low. Bundled Topaz software suite handles capture and verification without adding system load.

Sustained load behaviour

The pressure sensor and LCD maintain consistent responsiveness during back-to-back signing sessions throughout a business day. The 410 ppi resolution captures forensic-quality biometric detail on every signature without degradation over time. Passive stylus operation eliminates battery changes or charging downtime. The 3rd-generation touch surface is rated for long life under high-volume commercial use.

Questions about this item

How do I connect the dual serial and USB interfaces to my POS system, and which step is often missed?

Connect the 9-pin D-Sub serial cable or the 4-pin USB Type A cable to the matching port on your POS terminal, then install the bundled SigPlus Pro ActiveX tools before first use; the step often missed is running the driver installer so the pressure sensor and backlit LCD are recognised.

What maintenance or replacement will the signing surface and pen need over time?

The 3rd-generation touch-screen signing surface and passive stylus are solid-state with no moving parts; only the stylus tip may wear after heavy use and can be replaced with a compatible passive tip, while the LCD backlight and pressure sensor require no scheduled service.

At what point does the 410 ppi resolution limit signature detail during sustained high-volume capture?

The 410 ppi resolution captures fine biometric and forensic detail for each 4.4 x 2.5 inch signature; under sustained use the limit appears as USB bandwidth saturation when many pads stream simultaneously, not as a loss of per-signature resolution.
