In case it isn't obvious, I wound up here as part of my efforts to figure out when paper checks go away completely. I don't think they're gone in less than two years, but I have trouble visualizing them still hanging around 10 years from now.
One of my other recent data points on eliminating paper checks involves my efforts to learn how to do a bank-to-bank transfer (both my accounts) without using a check to accomplish the goal. I contacted the bank I want to send money from to ask about setting up EFT, and they said _they'd mail me the paper form_. That is clearly something that needs a little adjustment.
