Credit Card Details

[malagabob]

Had to ring a credit card company yesterday ( the number was the genuine one )as I was having problems setting up a D/D
I went through the normal security questions, gave the 16 digit number expiry date etc.
But the guy then asked me what was the 3 digit number on the rear of the card was.
Is this right?

Yes, it's the security number. They always ask for it.

I've never known anyone ask for the rear digits. If you're sure it was a genuine phone number maybe he was new and didn't understand the protocol? Phone again and ask.

[Cloverjo]

Oh, Tilly posted while I was typing. It's probably ok then. I just don't remember that question when I've had dealings with things like that.

You are always asked for those digits when you buy online or over the phone. I don't think there's anything to worry about.

[fiction-factory]

Yes, it's how they know you have that card with you.

Thanks all

Perfectly normal. If you buy anything on-line you need to provide that number.

[malagabob]

I was aware of entering the numbers for on line shopping, but then you are using or should be using a secure site/page.
I have never given the 3 numbers to anyone personally.

That's why it's called a security number. The only chink in the armour is that if a card falls into the wrong hands it can be used on-line, but not where chip and pin is required.

I've often been asked for it when buying things over the phone. I don't think the actual card company has ever asked for the security number, though - they usually have security questions about the name of my grandmother's dog etc.

But basically, I suppose that's what the security number is for. You don't need it when paying in a shop.

jackdaw, they're talking about introducing digital security numbers that would change every hour. Battery-powered, apparnetly.

Was it a credit card or a debit.? The three digit number on the back of a debit card is usually asked for.

[Jackdaw33]

How on earth would that work? I have a gizmo for on-line banking with which I type in my PIN then get a 6 digit number to enter. If I don't enter it within a minute I have to start again.

this is the theory, jackdaw

'Theory' is the operative word.
