Okay so my question requires a bit of background:

All three of the Harper boys (Will: B06, Roy: B25, Jim: A45) have different designations yet are identical as they are clones. So, why does the Zeta Tech not view them all as one person?

In S2, the eye scanner at the Arrow Cave viewed both Roy and Will as the same person. When it scanned Will's eyes it recognized him as Roy, who was already inside, then the alarm went off. I am supposing the technology must be different and I am guessing the Zeta tech is more advanced. But then how does it function? WHAT differentiates them?

The only two things I could think were age and physical attributes. All three Harpers are different ages (technically with Jim being the eldest and Roy being the youngest due to time spent on ice) and have differing physical attributes (hair, facial hair, muscle mass, height, limbs in Roy's case.)

My main question is: how does the zeta tube recognize people? Is it through blood, through DNA, through physical attributes? And how can it tell the Harper boys apart?

Thank you so much and really enjoying S4 thus far! :)
