I see that the Square Register is listed as one of the hardware devices we can interact with under [Commerce](https://developer.squareup.com/docs/commerce) in the docs. But it’s not clear how we can connect with it. Can we actually build apps that connect to the register? Is there a list of capabilities that are compatible? It’s not clear if the listed APIs can actually be used with the register

Hi @mmaccou ,

Thanks for linking the doc in question.

There is no directly related SDK or API for the Square Register. There is no way to build apps on the Square Register. There’s no way to run your own POS software on the register.

I believe what the doc’s trying to suggest is that with APIs like the Orders, Payments, Customers, etc., you can view transactions created via API on the Register, and vice versa, see the transactions from the register via API.

If you’re looking to take in-person payments for your own application or make your own POS, I would suggest considering the [Mobile Payments SDK](https://developer.squareup.com/docs/mobile-payments-sdk) or [Terminal API](https://developer.squareup.com/docs/terminal-api/overview) ([technical](http://developer.squareup.com/reference/square/terminal-api)).

Let me know if you have any other questions.
