I read about this need for biometeric gear, fingerprint technology, etc. Here we see one of OUR cultural characteristics. We always seem to go for a technological solution to whatever problem we face. Can't speak the language? Get me one of those Star Trek translator boxes! Sorry, but technology isn't always the answer. In some situations, if you don't know the culture and the language, all the biometric gizmos in the world are not going to make up for it.
