And I feel the pain of this system when I travel to the UK. I live in Belfast 1/3 of the year and there isn't a single American bank that will issue me a chip-n-pin card. I haven't investigated how hard it would be to set up a UK credit card. Large stores usually accept American cards but I've had many smaller shops tell me they can't do a swipe anymore.
My experience visiting the UK from the USA was that everywhere would accept a swipe transaction, but that the staff didn't necessarily know how to do it (many were too young to have ever had direct experience of swiping a credit card).
The two things that helped were 1) being patient, and 2) carrying a pen.
The thing that didn't help was having a British accent and an American credit card...
I've noticed a chain of grocery stores in my area installed new card readers recently which appear to have a slot above the LCD screen. What I haven't figured out yet is whether or not that slot is aesthetic or a chip-and-PIN reader.
I have a Wells Fargo credit card that has a chip in it, I just haven't bothered to try yet.
