One is based on the photoelectricity diffusibility reflection theory. In this method, an expensive photoelectricity sensor is laid closely with the signatures which are lightened by red LEDs. It will be judged by the analog reflection value from the detected area whether the signature is good or not. The other method uses the complex electronic image processing technology to identify some content in the signature.
