I actually have to write checks regularly to pay my utility bills, or I have to pay a $2.00 convenience fee to have the transaction processed by a third-party hired by the state. Not to mention, I randomly receive checks in the mail from events I speak at or for travel reimbursement or university reimbursement or the like. I love that I can snap a picture and wham my check is deposited.
Not to mention things like Apple Pay, which, without support, configuration, and advice from the banking industry wouldn't be a thing. Naturally they created the technology for the phone, but banks do the rest. How is that not innovation?
