The NatWest ones require your debit card too.

[Andy Burns]

So do the Barclays ones, and the Natwest/Barclays cards and readers are interoperable.

[Scott]

As indeed you can use someone else's device to generate a code (except I think one bank (HSBC?) uses a different system).

[Dave Plowman (News)]

With my Barclays one, you also need your card. Thus they would need your card, PIN, and logon details.

[Scott]

Interestingly only a debit card. Barclaycards do not work.

[Dave Plowman (News)]

I'd say it would need to be the card associated with the account? You can have a Barclaycard and no Barclay bank account.

[Scott]

Actually, that must be right. The card reader does not need to be associated but the (debit) card does.

[tony sayer]

They still need your card!..

[Richard]

Really!? And I thought the chip came with fish. Better tell Andrew, eh?

[Richard]

Barclaycard is a Credit card. Different standard to Debit cards. A credit card won't work in a pin sentry device, as that is intended for online banking. They also use pin sentries in my local Barclays branch to do transactions over the counter.

[Scott]

If you have two accounts / two debit cards, can you use the 'wrong' debit card? Otherwise, it's easier than this (card needs to relate to account, full stop).

[Dave Plowman (News)]

No. You need the debit card associated with the account - or rather you do with Barclays. At home, that is.

The telecoms co i used to work for supplied us with laptops installed with a Nortel VPN and an RSA key and as far as I can remember each one was tied to the laptop and needed a pin as well.

When logging in the device showed 5 bars and you had to enter your pin before the 5th bar appeared so it would synchronise with their server. Using a collegues RSA key would not work without the matching pin.

[Bob Eager]

As I thought. So the fact that the readers are interchangeable is not a problem.

Nominally, 1.5 volt but new cells typically show an extra 50 to 100mV higher than this nominal 1.5v rating.

[Scott]

Thanks. MIne is Barclays and the original question related to Barclays, so I think that is the question answered.
