"Omega NFC" is the advanced version of our best seller device "Omega".the Omega NFC for accurate signature capture on a signature pad with a large 12.5 cm (5") full-colour display and an integrated NFC reader, perfect for the paperless point of sale (POS).

The Omega NFC is an advanced development of the normal Omega pad model. The new hybrid model offers two devices in one: a signature pad and an NFC reader. With this unique combination, you can set basic accents at your point of sale. The smart integration of two devices into one not only saves space, but also money, and enables seamless integration into your existing processes. Like all other models, are fully developed and produced by signotec Omega NFC itself - "Made in Germany".


NFC is the international transmission standard for wireless data exchange and enables extremely secure data Transfer. The special feature of NFC is that two devices (e.g. Omega and another device) can be kept at a distance of a few centimeters to initiate a data transfer. The application areas of the NFC are very diverse. NFC can be integrated in PC applications but also in PC peripherals, as here in the "Omega". The Near Field Communication can also be embedded in individual chip card readers and electronic identity applications (eID).




  • Combination of a signature pad and an NFC Reader
  • Large 12.5 cm (5") full-colour display
  • Pen with special, resilient pen tip
  • Simple, contact-less readout of data (eg. from a NFC-enabled card)
  • Only one USB connection needed
  • High data quality through electronic detection
  • Fast, modern handling with the customer
  • highest security through unique security features and RSA encryption
  • Individual design possibilities (colors and logos)

Software & Integration

The NFC reader supports CCID drivers and smart card reader functionality inboth Windows and Linux operating systems. On the applications side, the NFCreader (NXP PR533) integrates under Windows into the Microsoft Smart Card API and under Linux into the corresponding APIs. More information about integration can be found here:
To use NFC you need a software that utilises the NFC standard. Integrators can use the NFC interface provided by Microsoft or Linux.

The 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".
