What is the reliability of a Signature Pad ?

Calculated non-LCD pad MTBF is greater than 500,000 hours (greater than 50 years). Calculated LCD pad MTBF is greater than 100,000 hours (greater than 10 years). Lite-series touchpad systems MTBF at about 100,000 signatures. Actual field use experiences are really what determine the reliability of the tablet, and Topaz has a lot of experience in the field. This includes our signature pad capturing over 100,000 signatures in the field, and even with the plastic signing surface scratched and cut up, there was no failure. Topaz units have survived being driven over by a small truck. In addition, the tablet functions properly through least 50 feet of serial cable. The Topaz pen has been qualified to over 30 million activations and high G-forces. Our experience is that for field reliability, it's the technology and also attention to all of the little things that makes the difference. Beware of tablets which specify 100,000 signature lifetime, but with a limit of 100 grams pressure for signing. In practice, these tablets may only last for a couple of thousand signatures.
