Our VISA credit cards have no chip. They are the common ones with the magnetic stripe.
Last year we visited Scandinavia. Everytime we used them, as they didn´t have chip I had to tell them I had no chip and I had to sign. Most of the times they solved the situation pressing some code and no problem. A few times they were not accepted.
After our trip, in June 2013, some relatives visited the same places and they coulnd´t use VISA CREDIT CARDS WITHOUT CHIP.
As always, I thank you in advance!
