• Signature Pad Zeta

    Description of the signature pad "Zeta" by signotec with a monochrome LCD screen.

  • Short Summary :

  • Signature Pad Zeta

    is an unbeatable combination - from the already proven signature pads Sigma and Gamma. During the development process, explicit attention was paid to perfectly combining the advantages and technologies of both models: The German Design Award winning design of the signature pad Gamma and its robustness of the ER technology meet the low-cost monochrome display of the signature pad Sigma.

The LCD

Signature Pad

Zeta is the latest model in the signotec family and has an approx. 4.5-inch (11.4 cm) monochrome display and the popular, durable ER technology. The sensor reacts exclusively to the special battery-less pen and not only records movements with 1,024 pressure levels and up to 500 Hz sampling rate, but also detects the movements of the pen in the air.

This enables the signature to be digitised in great detail and thus has a correspondingly high evidential value in court proceedings. Due to the device design, a very long lifespan of up to 30 million signatures can also be expected from this pad.The signature Pad Zeta thus perfectly closes the gap between the low-cost signature Pad Sigma and the signature Pad Gamma as the most cost-effective device with ER technology so far.

Like all models of the signature pads, the signature Pad Zeta was developed entirely in-house "Made in Germany ", combining decades of experience and competence. Furthermore, all signature pads have unique security features, such as the signature and RSA encryption in the pad's secure memory. Due to the flat surface without edges between sensor and housing, all pads offer an extremely comfortable signing experience.

The 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 v2.1
  • Certificates can be certified by a Root Authority
  • Supported hash algorithms are SHA-1, SHA-256 and SHA-512.
