Highest security
icon encription
  • The biometric data of your signature (pressure, speed and writing direction) is already securely encrypted in the pad and is always securely transmitted.
  • The StepOver software solutions bring this signature into the document. The connection is asymmetrically encrypted with an RSA 4096 key.
  • The validity of the signature and the document integrity can be checked with freely available software (e.g. Acrobat Reader).
Optimal for right and left-handers

Signature pad with a black and white screen – flat and yet extremely stable. 40% of the 1 cm height is due to the wall thickness of the robust case.

Thanks to the standard mini-USB socket, the times of compromising with the cable length are finally over. While people like to use a long connection cable on the PC at the desk, this is rather a hindrance in mobile use. The annoying unplugging under the table at a stationary workstation is also no longer necessary.

The signature pad contains a public key of a notarially generated key pair. With this key, the biometric data of your signature is already securely encrypted in the signature pad. This means that this extremely sensitive data is never stored in decrypted form on your computer, which may be insecure. The private key required for decryption is securely stored with the notary.

In addition, each StepOver signature pad has a unique certificate for digital signature (4096 bit RSA). This certificate can optionally be used to digitally sign the document. This makes it possible to uniquely assign the document to a specific signature pad at a later date.

As standard, StepOver delivers the signature pad naturaSign Pad Classic in a practical protective box for transport and shipping (the protective box is included in the list price). The protective box is made of high-quality and recyclable plastic (polyamide) and was specially developed for the high demands of constant use in a harsh environment. The protective box provides space for the signature pad and the required USB connection cable.

Using the TCP and Citrix extensions, the signature pads can also be used in a remote desktop and Citrix environment.
