Signotec A4 Colour LCD Signature Pad Alpha
The Alpha Pad is the newest product from the Signotec development department. It differs substantially from his two brothers “Sigma” and “Omega”. That affects not only the size, but rather the technology regarding to capture the coordinates of the pen and even the parameters for processing.
Thanks to its display size of 15,6″ it is the only Signature Pad on the market, which has the ability to display A4-documents in their original size. In doing so its not just a monitor extension, but rather a “real” Signature Pad like Sigma and Omega with the same powerful free of charge programming interface.
Even the requirement of the written form, which is e.g. essential for loan agreements, can be fulfilled with the Alpha Pad:
The signee places the original document on the Pad and then signs both, the original and the digital document, simultaneously via digital blueprint.
If the paper document is not required as a result of the principle of freedom of contract, the ballpoint pen cartridge can simply be replaced with a plastic one. It is then possible to electronically sign full-page documents directly on the high-resolution display.
Large pen pads are highly sought after by users who want to display complex documents that have to be signed. Delivery notes with several items or multi-page contracts that you can scroll are just two examples. Standard pen pads are just too small for this. While there are already large devices on the market that enable signing, these are usually just monitor extensions where the signer still sees all the other applications running on it.
To make the displayed content remain private, the Device is provided with a “privacy viewing” technology. Thanks to that the content is protected against prying eyes.
The Pad stands out through its plane surface, consisting of hardened mineral glass. To attach further devices, there are 2 USB-ports on the back of the device.
You are able to “print” documents directly into your Pad and sign them on the spot. The signature is going to be placed exactly on the same position in the electronic document as on the pad. So there is no need of configuring signature boxes.
The Alpha is going to be connected via USB or Ethernet. So it can directly be used on the PC or in the LAN. Of course there is also an Alpha version for a terminal server environment.
If the Pad is not in use, it´s also suitable as an excellent advertising medium for slide shows, thanks to its huge internal storage which also caches statistic content.
A further advantage is the open VESA-bore, located on the back (VESA MIS-D 100C, 100x100mm) for easy mounting.

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.
