LCD Signature Pad signotec Sigma
The LCD Signature Pad "signotec Sigma" is the little brother of the successful Signature Pad "Omega". The "signotec Sigma" is a device to 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 therefore ideal for the mobile use. When used stationary it characterized with its flat design and the optional pen holder.
The signotec Sigma Signature Pad is available with and without backlight!
The signotec 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 flushed 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 rate also allows for "swinging" 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, 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 PC is encrypted, thereby 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 matching perfectly.

The signotec pads (Omega firmware 1.25, Sigma 1.16) have the highest security mechanisms available. This allows 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 biometric data of the signature can be RSA-encrypted inside the pad using a public key.
- RSA-signature of the displayed content and signature.
- Upon delivery, each pad has a separate and unique RSA certificate for signing.
- Storing of custom RSA-certificates inside the pad.
- The pad can generate a RSA certificate.
- Supported schemes are RSA PKCS # 1 v1.5 (with or without the hash OID), PKCS # 1 v2.1
- Certificates can be certified by a Root Authority
- Supported hash algorithms are SHA-1, SHA-256 and SHA-512.
For details please refer to the documentation.
The case of the signotec Sigma is available in any colour and customer logos can be imprinted on the device.
The pad comes with a free of charge software package consisting of the signoPAD-API and the signoPAD-Tools. Updates comes with no extra costs!
Recommendation: A useful addition for signing of PDF documents is signoSign/2.
