signotec Gamma LCD Signature Pad

The signotec Gamma establishes new standards in terms of design and functionality. The flat signature pad impresses with its robust sensor surface made of hardened special glass with ER technology. The high-resolution approx. 5″ (12.6 cm) colour display enables excellent presentation of graphics and texts. Two different pen holders ensure the best ergonomics for the respective application.

The included special pen and sensor guarantee superior signature capture quality – with the special feature that the movements of the pen in the air are also recorded. The battery-free pen with replaceable tip records 2,048 pressure levels and transmits the signature at a rate of up to 500 Hz. Thanks to the robust construction of the sensor, a very long lifespan of up to 30 million signatures can be achieved.

The signotec Gamma won the renowned German Design Award in the category “Excellent Product Design – Computer and Communication” when it was launched in 2016.

The signotec signature pads 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 v2.2
  • Certificates can be certified by a Root Authority
  • Supported hash algorithms are SHA-1, SHA-256 and SHA-512.
Complimentary signoPAD-Tools software:
  • signoImager/2: Capturing and saving of the signature as an image in the system or clipboard
  • signoIntegrator/2: Capturing of the signature as an image and insert as graphic at cursor position
  • MS-Office Add-In: Insert a signature as an image to the Word and Excel document
  • RSA Manager: Certificate management
  • signoReset: Resets the signotec signature pads to the factory default
