Compact signing surface for desk-based workflows

The Ambir SP110-S2 provides a 4.00" x 2.00" active signing area with a 320 x 160 backlit display and 104 DPI resolution. Its electromagnetic sensor captures pressure-sensitive strokes using the included non-proprietary stylus. The unit measures 6.30" x 4.70" x 0.40" and connects via USB without requiring a separate driver installation for basic operation.

USB interface limits driver-free use to Windows

The pad relies on a standard USB connection for both power and data, with the manufacturer noting that software downloads are required for full functionality. Built-in AES encryption and RSA signalling secure the biometric signature data during transfer. TWAIN and WIA support allows the device to appear like a scanner to compatible applications, enabling resolution adjustment, rotation and cropping of captured signatures.

Check that your workflow supports the supplied

Before ordering, verify that your point-of-sale or document system can integrate with the signoSign 2, signoIntegrator 2 and signoImager 2 utilities, which run on Windows and handle PDF placement, one-click import and image export in TIFF, PNG, BMP, JPEG or GIF formats. Buyers needing native macOS or Linux driver support, or those requiring a larger signing surface for full-name signatures, should consider alternative devices.

Questions about this item

Should I choose the 4.00" x 2.00" model or a larger signing area?

The 4.00" x 2.00" active area matches the SP110-S2 dimensions of 6.30" x 4.70" x 0.40" and fits on virtually any desk while still capturing full signatures.

How does the 104 DPI resolution affect captured signatures in daily use?

The 104 DPI sensor combined with a 320 x 160 display resolution records pressure-sensitive strokes with enough detail for legal documents and biometric verification.

What does the USB interface mean for setup and compatibility?

The USB connection requires no driver installation and works through the Windows System Tray with included signoIntegrator 2 software for one-click import into any Windows application.
