SignatureGem 1 x 5 is a small electronic signature capture pad with a large signing area. Designed for accuracy, reliability, and portability, the SignatureGem 1 x 5 features a pen with interchangeable inking and plastic tips, small size and weight, and is powered only by your computer's data port. Unlike pressure-sensitive touchpad systems, the digitizing pen allows the sensor to be mounted inside a hard plastic casing for ruggedness and long life.
