SHORT DESCRIPTION
Extremely flat input device for precise capturing of signatures. Monochrome 4" (10.5 cm) display with a high resolution for the brilliant display of the signature in real time. The compact size is ideal for stationary and mobile use, e.g. for service engineers. The device has a USB connection cable with approx. 2.0 meters length.
BACKLIGHT
The signotec Sigma signature pad is available with or without backlight. The device with backlight is particularly suitable if you have to work under changing or unknown light conditions, e.g. in field service.
FTDI (vCOM)
The signotec Sigma signature pad can optionally be supplied with an FTDI chip. This chip converts the USB signal into a virtual COM signal, so that the device can be used in virtual environments, such as Remote Desktop (RDP) or Citrix.
The mode can not be changed from USB to vCOM or vice versa.
For operation, the free FTDI driver is required. You can find it in the download area of our website.
DELIVERY
The delivery includes:
- Signature Pad signotec Sigma
- USB connection cable (fixed)
- Special pen with springy tip (changeable), attached with cord to the pad
EQUIPMENT
Basically, everything you need is included. As an optional and useful accessory, we also offer a protection soft-case and screen protectors, which significantly extend the life of the sensor surface.
SOFTWARE
Our basic software ("signoPAD-Tools") for simple recording of the signature as an image (e.g. in Word and Excel) is available as a free download at www.signotec.com.
NOTE: If you want to sign PDF documents with legally binding, you will need our "signoSign/2" software.

RSA Features
The signotec 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.
