I have read that american credit cards do not work in London.
Is this true?
No it is not. Where did you 'read' this?
Now who told you that?!
The only card that isn't accepted is Discovery and some traders don't like Amex but Visa & Mastercard are accepted everywhere from the smallest newsagent to the glitzyest hotel.
There is a difference, in that US credit cards are mostly chip and signature, not chip and pin which is usual in Europe. In that case, you have to sign a credit card receipt rather than key in a pin number. It's an antiquated system, but should work.
"It's an antiquated system, but should work."
Chip and signature cards are still available in the UK, not antiquated, just different.
I too am interested to know where people get information such as American credit cards not working, Uber being banned in the UK etc.
Fake news anyone?
Mine all worked in June, chip & signature. Even the old swipe and sign work but a chip card is less likely to elicit puzzlement from the clerk or attendant! (And was it really necessary to describe the U.S. system as "antiquated?" Not everything which is true need be stated.)
My card from here is chip and pin and contactless. Yet the little machine always spat out a slip to sign rather than ask for the pin. So no problem really. Mastercard, if that helps.

Many, many of my American friends refer to their US credit cards as something similar to "antiquated". Very little contactless and only just catching up with 'chip n pin'.Edited: 16 October 2017, 20:14
Interesting article Charliie.
I've recently spent a month in the USA and 99% of my card transactions were swipe and sign. The bizarre thing is that NO merchant checked the signature against the back of the card (I saw one person sign for a round of beers, by drawing a picture of the male genitalia!!!) which meant that all transactions were unauthenticated.
I used my card in a few public transport ticket machines including the New York subway. To authenticate the transaction I had to enter a zip code and not a pin - how bizarre. As a non-US person I entered 00000 and the machine accepted it, so again totally unauthenticated.
It is such a different world :-)
Chip and sign cards are valid, but you may need a supervisor. Chip and pin is so ubiquitous here that many sales assistants will never see a chip and signature card and/or may not be authorised to accept them. A supervisor will know what to do.
