Signotec Sigma

The┬ásignotec Sigma is the smallest signature pad with an approx. 4″ (10.4 cm) monochrome display (LCD), which is optionally available with or without backlight. The RTP sensor with a special foil surface captures the handwritten signature with a sampling rate of up to 500 Hz and 1,024 pressure levels. In addition, simple graphics and text information can also be shown on the display of the signotec Sigma.

The signotec Sigma without backlight is the best choice for well illuminated areas. The signotec Sigma with backlight, on the other hand, is also excellent for use in changing light conditions. The compact design makes the signotec Sigma ideal for both stationary and mobile use. The optional protective pouch is particularly useful during transport.
