naturaSign Pad Mobile

The signature pad with first-class ergonomics for mobile use

Highlights of the naturaSign Pad Mobile

Optimal for mobile use

icon remote work

This signature pad is both rugged and compact in design. Intended for mobile use, it is thinner than a ballpoint pen and fits in any laptop bag.


Large black and white screen

Pad de firmas- Simbolo

The large black and white screen allows text to be superimposed and provides plenty of space for signing. 


Ergonomic Design

The flat touch screen paired with a particularly easy-to-clean housing surface enables ergonomic signature capture without corners and edges. The “rotate” function rotates the signature line by 180° and thus also enables left-handed users to sign comfortably.

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).


This StepOver Signature Pad is suitable for setting up a system for simple and advanced electronic signatures in accordance with eIDAS.

The naturaSign Pad Mobile has been specially developed for the requirements of mobile use, such as in the field. Thanks to the large black-and-white screen, the extremely flat design (0.95 cm height) and its rounded edges, the naturaSign Pad Mobile is at the same time an extremely compact, yet stable and convenient device for signature capture.

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.

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