Vixen said:If you remove the CVC digits from your card, then your card with not be authorised for any referral. So no high value purchases or making lots in one day for a start.
As far as asking for security passwords goes, if Natwest/RBS call, they will ask for two letters from the password if it is there. With us at least, if you ever recieve a call you're unsure about, call the number on the back of the card. During the day we can check with our fraud departments if they have called out, or there are folders with a bunch of contact numbers to check against. If someone says they can't check for you, the weekend team leaders are on or they are being lazy.
If a message is left, there should always be a name and reference number given.
Very similar with HSBC.
I wasn't aware that other banks ask for pass details when they call you. Neither HBOS, HSBC or the other couple I've had personal accounts with have done this.
If Natwest are doing this it's a very questionable procedure.
On the one hand, Natwest are sure they are dealing with you. On the other hand, you're giving out vital information.
But one thing that stands is that if you're entirely unsure, say you're unsure, and that you'll call back (and remember to look up the number yourself!)
