According to another post, the text reads:

&gt; And if there are not two men (available), then a man and two women, such as you agree for witnesses, so that if one of them (two women) errs, the other can remind her.

Nothing about veils, just about whether a woman can accurately repeat back what she sees and hears.

Ahh I see it's from 2:282 

The explanations I found for this refers to how women were typically indoors (back in those days) say women  are more emotional and might not be able to recall the incident correctly...which is... definitely sexist in my eyes. 

Not exactly what OP here said but yeah thanks for the source.

The veils thing was what I learned in school from my Islamic teacher when we would analyze verses. If women wear niqaab only another woman or her husband (and male blood relatives) can see her face. So if there was a situation where they needed to confirm her identity another woman would have to be present but I see this isn't that same verse thanks again.
