All signs point to no. Square wants to be a prominent brand in the eyes of SMBs and consumers (e.g. Square Register, Square Wallet.) They don't seem interested in offering APIs or other white-label tools that help app developers feature their own brands and experiences. Seems like Cardflight clients can integrate payments into their own app experience, rather than having to push CardFlight's, Square's or anyone else's brand.
