yes, the keyword being "use" - as in, consciously and deliberately placing their wallet within a few centimetres of the reader.

In america lots of fast food places dont require a signature or pin for low value transactions (eg subway). I thought it was great, much faster and more likely to use my card than cash, with all the hassle of fake notes and wrong change or the fact that everytime I break a note the rest of money seems to flitter away.

Get with the times people, the system really is a lot faster than a cash/chip and pin transaction. I want one and more shops to support it - this is the future.

Because once the transaction has gone through it won't then accept a second payment method.

If you select cash the reader will not power up and vice versa.

You cannot pay twice in such a manner with a contactless card.

Presumably though, one would have in thier wallet thier oyster ( with thier weekly prepaid travel card on) and their contactless card.

The machine isnt going to differentiate which you wish to gain access with is it?

The Oystercard uses the Mifare protocol - unless you have a bank card specifically designed to support Oyster, no.

The only one that I know of that supports both protocols.

What is Barclaycard OnePulse?
Barclaycard OnePulse is a unique and innovative product that provides the convenience and speed from having three cards in one - Oyster card, Credit, Cashless. It is:

• A card with all the benefits of an Oyster card
• A credit card for all your normal purchases (using Chip & PIN)
• A credit card with contactless payment, a new cashless way to pay, allowing you to make purchases of under £15 more quickly and conveniently by simply passing your card in front of a secure reader rather than typing in your PIN.

If you are paranoid (needlessly I might add), search on youtube. There are dozens of videos showing how to break the chip so it won't read anymore.

Well, I took a look and these are all American youtubes and basically tell you to smash a screwdriver or other pointed object through the chip.

I kind of think that whilst this probobly will, indeed, disable the contactless technology, it will likely also disable your chip&pin, as well as making any retailer pretty suspicious when you try to use your card conventionally!

Not impressed!

But Barclaycard are ademant I have to have it. Only way not to is to cancel the account (tempted but I have a really good legacy cashback deal!).

If you are really that worried, just be careful that you only destroy the RFID transponder and not the EMV chip
