signotec Omega LCD signature pad

the signotec Omega is a signature pad developed and produced entirely by signotec, “Made in Germany”, with an unsurpassed price-performance ratio. With its external dimensions of 180 x 191 x 15 mm it is extremely compact and appealing in design, so that you can set clear accents at your POS with this device.

The extremely flat signature pad impresses with its flat surface without edges between sensor and housing. The design allows a highly ergonomic signature. The pen and sensor give you a writing sensation similar to that on paper. The rounded sides also allow a smooth transition of the ball of the hand from the signature pad to the table, without any disturbance during writing. The pen itself has the size and feel of a real ballpoint pen and does not require any electronics or power supply. This passive pen is inexpensive to replace and the pad can still be used if lost.

The signotec Omega offers many application possibilities in stationary operation, for example at the point of sale (POS). The vertical holder enables the pin to be gripped quickly and easily.

In addition to the functionalities for signature capture, the signotec Omega can also be optionally equipped with an additionally integrated NFC reader.

Near Field Communication is the international transmission standard for wireless data exchange and enables extremely secure and fast data transfer.

The application areas of the NFC are very diverse. NFC can be integrated into PC applications and peripherals, as shown here in the “signotec Omega”. Near Field Communication can also be embedded in individual chip card readers and in electronic identity applications (eID).

Security Features (RSA)

The signotec 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.


* The security features only refer to the signature capture via signotec signature pads. Other functionalities of hybrid devices (eg NFC or fingerprint) may have deviating security standards.

** One of our paid signature applications is required to sign PDF documents. For Windows we recommend our software “signoSign/2”.
