I just read out at Security Focus, that UK banks are implementing a delay of 1 day for transferring money between accounts. They are allowing for additional time between the request of a transaction and the actual moving of funds to notify account holders and hopefully prevent fraud. This delay is added only to transactions between to sources the first time. Subsequent transaction will be trusted and executed without delay. Unfortunately, this will only apply to transactions between accounts within a single financial institution.
I still am amazed that I don’t receive an email or SMS message when funds are transferred in and out of my bank account. This is an excellent idea and should be adopted universally by all targets of financial fraud. There are exceptions (i.e. stock trades) but we still need to be thinking along these lines.
