With XX’s tag line I feel that you basically nullify your signature entirely. Ergo you make no commitment at all. Which is fine because the commitments are all made on the bills by the US Treasurer and Secretary. However this leaves your bank in a position where they are earning no money in any of your transactions. So you may encounter resistance, especially if you are earning any “interest” on any of the accounts.

I plan on utilizing my Credit Union's "Snap Deposit" smartphone app to take a picture of my checks and deposit them that way. Interestingly, I found this bit of apparent legal advice in the app's FAQ:
"Be sure your checks have no evidence of alteration or contain a restrictive endorsement."
