The life pods I have aren't biometric, but they do make a special edition. I have a Lifepod XT for the range, and the biometric scanner works great on that. I wouldn't expect it to be any different.
I saw a video of a guy using a web cam to highlight the pointer on his scale. I looked around and found a nice cheap(5.00) stand for an Iphone, grabbed an old Iphone 6s I had lying around and here ya go...
you have to put the phone on video so it doesnt shut off but it works great.
