Signature Pad | Sigma


Like the other signotec models, the signotec Sigma is made in Germany and was developed entirely in-house, combining decades of experience and competence.

At a height of only 1 cm, it guarantees the very best quality and functionality. It has a unique flat construction and the flat surface without edges between sensor and housing which enable a highly ergonomic signature.

The Sigma is extremely compact with an unsurpassed price-performance ratio of 160 x 120 x 10 mm, making it ideal for mobile use.  However, its flat and compact design also allows it to impress in stationary operation.

Its 4" (10.5 cm) sensor allows lively signatures to be captured without getting caught in the sensor's limitations. This is indispensable for a true-to-life and conclusive capture of the signature.  Extensive text information can be displayed as well.

The LCD screen is available with or without backlight. The signotec Sigma without backlight is the best choice when it is used in well-lit areas and the most cost-effective variant is required. Alternatively, the signotec Sigma with background lighting is an excellent choice for darker operating conditions.
