I used to pay my very old landlord with personal checks for a chase account. At some point somebody, (I suspect the part time janitor) got my account number and tried to commit check fraud nearby. This was unsophisticated, an inkjet printer sort of attempt, but nevertheless forced me to close the account, get new numbers, and update all of my direct deposit and bill pay settings on other accounts. It cost me many hours and at least one late fee. So the obvious feature I would like from a regular, boring checking account is one-time random numbers for everything. Every check should have a unique, completely opaque number. Every time anyone wants an account number for direct deposit, wire transfer, bill pay, or anything else, I should be able to instantly generate a new, disposable number that works until I chose to retire it.
