Select a signature pad below to begin. Topaz SignatureGem pads are best used in applications where signature volume is high and/or the pad is used in a public area and as a result, there is the potential for abuse. SigLite pads have all the high-quality biometric and forensic techniques of Topaz pads with lower-cost/less expensive technology than the SignatureGem pads.
