Does anyone know if you can now connect to the Square payments processing hardware through the API? I would like to process in person payments through Square but keep the user experience in my application.

Yes, this functionality is now available through the Register API (announced alongside the ECommerce API)

Unfortunately that kicks the user out of your app and into Square's temporarily. And according to the TOS, the customer needs to be supervised by a merchant employee during the transaction. Ideally you would be able to handle the customer's payment seamlessly and unsupervised within your own app.

If it's unsupervised and in another app wouldn't that just be ecommerce? Or are you talking about something like a kiosk?

Yeah something like a kiosk. I want to be able to process card swipes instead of making users enter their card number (as in the Ecommerce api). The additional benefit is that you get charged the 2.75% card present fee instead of the 2.9% + $0.30 card not present fee.
