Why would banks say that they, too, are worse off because of the EFAA?

Since the Expedited Funds Availability Act (EFAA) was enacted, millions of people have fallen prey to various types of check fraud. In a common scam, the fraudsters contact an individual—via e-mail, telephone, or letter—and say that they will send that person a check for a certain amount if he or she agrees to wire some of the funds back to them, typically to cover “fees and taxes.” The victim receives a check and deposits it in his or her account. A day or so later, when the law says the funds must be made available, the victim confirms that the funds are in his or her bank account and wires the requested amount back to the fraudsters.
