The rugged Topaz™ SignatureGem™ 1x5 SigPad utilizes electromagnetic technology with an active pen to reliably capture signatures for long-term use in commercial-grade applications. The 1x5 pad captures signatures only. SignatureGem™ 1x5 has a large signing area and is designed for accuracy, reliability, and portability, the SignatureGem™ 1x5 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.
