SignatureGems are designed for accuracy, reliability, and portability, we offer three basic LCD signature pads - the 1x5, 4x3, and 4x5. The LCD 1x5 and 4x3 series are also available with a touch-sensitive SigLite sensor and stylus in place of the electromagnetic Gem-series pen and digitizer. The HID USB models support interactive applications allowing data to be displayed on the LCD as well as signatures captured.
