Number one advice I give my family: never give out any information (no matter how inconsequential it seems) to a person purporting to be from a company calling you. Hang up and call the company yourself using a trusted number (e.g., the number on the back of a credit card).

Banks should really just stop calling customers and taking them through security. If there's something urgent, the protocol should be that they call you, give you a ticket number, and tell you to call them back on the bank's standard number for customer service. Anything else just conditions people to expect incoming calls with security questions which will always result in scammers finding a way through.

This can also be scammed due to the timeout "feature" in telephone systems. Ie, the scammer calls, tells you to call the number on your card. You believe they hung up, but they are still on the line. When you pick up your phone again, you're still contected, and they're playing a dial tone.

Now the real trick is to get this to work with cellphones :)

How many people still use landline phones? I don't know anyone.
