wire transfer, or walk into the bank and have them create a cashier's check

and a normal check is the same as an ACH transfer, so I will do the ACH transfer

or lawyer's escrow

and every other larger transfer has been cryptocurrency in my life, its been over a decade of that unlimited amount, zero scrutiny, 24/7/365 option

(I've tried various other country's and international system transfers, and the convenience is completely over-embellished, and limited to small amounts at best. and yes, I'm talking about instant SEPA in European banks. A lot of people don't have balances in crypto currency so it would just be more inconvenient for them to get into that system)

but the only time I'm personally using checks are because a new employer's HR system wants me to write VOID on a physical one, and I've opted to photoshopping a template with my account number and routing number, because checks are the same as an ACH transfer, and they could have just asked me to copy and paste those numbers into a input field

There was a time that printed checks had to use special laser toner called MICR Toner that was magnetic so the magneto readers could machine read the check bottoms routing and account numbers, but that went away when the Fed just ran it all as ACH/ electronically and optically scanned checks around the time mobile deposit and well after OCR became a thing. Last I checked the rule was still present in the statues.
