Signotec LCD Signature Pad Sigma

The signotec LCD Signature Pad "Sigma" is the little brother of the successful Signature Pad "Omega". The "Sigma" is a device for capturing signatures, fully developed by signotec and made in Germany, with an unbeatable price-performance ratio. Measuring just 160 x 120 x 10 mm, it is extremely compact and is therefore ideal for mobile use. When it's stationary it still shines with it's flat contruction and the optional pen holder.

The Sigma signature pad sets a new standard for electronic signature capture devices, in terms of its size and the resolution of the display. Among the device’s unique features are the outstanding display of graphics and text, the technical properties for digitising signatures, its extremely flat design and, above all, its smooth surface and a sensor that is flush with the housing. This design enables signing to be highly ergonomic. The rounded sides also allow the heel of the hand to pass fluidly from the device to the table without disrupting the signing process. The high sensor also allows for sweeping signatures, without the user inadvertently reaching the limits of the sensor. This is vital to ensure that the signature is captured naturally and securely. Furthermore, extensive graphical and textual information can be displayed, which often plays an important role in stationary use. As a result, the pad is also an inexpensive alternative for stationary applications. The transfer of data from the pad to the PC is encrypted, which is why it is not possible to spy on the biometric features of the signature. Since the electronics, firmware, drivers and applications have been developed by signotec itself, the hardware and software are ideally matched.

The signotec pads (Omega firmware 1.25, Sigma 1.16) have the highest security mechanisms. This will allow a complete chain of evidence in dispute. Depending on the integration, different techniques are used:

  • PDF documents can be signed inside the pad and not in the insecure environment of the PC.
  • The biometrics from the signature can pad RSA-encrypted inside the pad and not in the insecure environment of the PC.
  • The pad LCD-screen content with the signature can be RSA-signed inside the pad.
  • Each pad has a separate and unique RSA certificate from delivery.
  • Saving from custom RSA-certificates inside the pad.
  • The pad can generate an RSA certificate inside.
  • Supported schemes are RSA PKCS # 1 v1.5 (with or without the hash OID), PKCS # 1 v
