Fingerprint technology has been with us for a long time, and it's improving. Fujitsu makes fingerprint readers, as do many other vendors, from Microsoft to Zvetco Biometrics. If you're looking for something more conventional than palm-based venous scanning, check out those products. Meanwhile, Hitachi is one of several vendors making finger venous-scanning systems that work on the same principle as PalmSecure.
Overall, PalmSecure and the palm venous hemoglobin imaging that it uses is a step forward for biometrics, offering a relatively secure solution that's sensitive to temperature changes, but is otherwise adequate. For restricted access--be it doors or highly sensitive systems--PalmSecure would fill the current technology gap.
