How safe is a checking account?
US checking accounts are not really secure, though many people use them. One form of check fraud has been highlighted by Prof. Donald Knuth and carried out by Frank Abagnale, as portrayed in the film Catch Me If You Can. Basically, anyone can write a check that would draw from your account merely by knowing your account number and your bank's ABA routing number.  With those two pieces of information (which are revealed on every check that you write), anyone can print a working check, either using a laser printer with MICR (magnetic ink character recognition) toner, or by placing an order with a check-printing company.  The only other missing element is a signature, which is a pretty weak form of authentication. When presented with such a check, your bank would probably honor it before finding out, too late, that it is fraudulent. A variant of this vulnerability is ACH funds transfers.  This is the mechanism through which you could have, say, your utility company automatically withdraw money from your account to pay your bill.  Unfortunately, the transfer is initiated by the recipient, and the system relies largely on trust with some statistical monitoring for suspicious patterns. Basically, the whole US checking system is built with convenience rather than security in mind, since other institutions are able to initiate withdrawal transactions by knowing just the ABA number and account number.  In practice, it works well enough for most people, but if you are paranoid about security, as you seem to be, you don't want to be using checks. The European system, which has largely eliminated checks in favor of payer-initiated push transactions, is safer by design.
