Late to the Square party. Maybe it's because I got mine right when they rolled out, but... $20 to open a basic checking account and I got my small card swiper for free. If they've changed things, cool, but my experience? They really didn't require anything out of reach.
I'm curious, though. Are homeless people not allowed to have a $50 smartphone with a monthly activation card? (aka, cheap ass burner phone). Are they not allowed to have had a bank account they keep a few bucks in to keep it open?
Hell, I kind of applaud their creativity if genuinely in need of help. Most people I know? Don't carry cash. Being able to shift their panhandling to fit with the current trend of not carrying cash just seems adaptive to me, not necessarily exploitative.
