I worked in payments. Respectfully, you really shouldn't be talking on behalf of Stripe.
It's clear that a card present product, which I believe is new for Stripe, is in direct competition with Square. Even if right now it's not being marketed towards the same customer base as Square, it's clear that with a few tweaks of the app plus a change in the manufacturing process, you could easily create Square-like POS systems. Why would Stripe leave out such a huge, proven market when it's clear this product is a stepping stone towards full POS systems?
