New palm vein technology

Additional information would be helpful...

Are you referring to taking exams through Pearson? If so, I have found that they use the palm vein scanner for new & old test takers during entrance & exit from the exam. The finger print reader has only been used during registration.

It's just a more tamper-proof method of ID recognition. I have no reason to suspect that either the fingerprint or the palm vein has anything to do with background checks. I believe they basically associate your photo with the finger/palm print, and then verify the prints when you check in/out of the exam. The palm vein imaging is harder to trick vs a finger print which could be done reasonably easily.
