Re:Hygiene and broken arms. (Score 1)

1. The palm vein sensor works at a distance of a few inches.. you dont need to come into contact with any metal plate so your concerns about hygiene are not necessary.

2. The palm vein sensor is not left or right hand coded. You are required to enrol when you are setup on the system. At that point you can choose which hand you want to enrol using the device and software. I assume the enrol process employed by the bank would be a bit like the IRIS enrolment at airports.. That is inside the bank they would offer you the opportunity to go through the enrol process. This would allow flexibility to change the hand with which you are enrolled in case you had your entire chosen hand in a cast or had it sliced clean off in an industrial accident or it might allow you to enrol both and use either.

Much of the above depends on how its been implemented by the integrator and bank. Where i have seen/used this before there was a fallback to a pin number system in case of issues such as the one you made in point 2 or to add an extra layer of security. As somebody else already pointed out, unlike fingerprint biometrics, you cannot use a dead hand, it has to be a live hand with bloodflow for the signature of the palm to be read by the sensor. The technology works very well and is impressive, it could be used in so many other applications, ATM is just an obvious one but i would sure feel safer if my bank implemented this technology.
