My citibank credit card sent me an offer to upgrade my card for no charge to a card with a chip. I looked into it and saw that it is chip-and-signature no chip-and-pin. Since it's free and doesn't change my card agreement, I'm going to get it, but I'm wondering if it will be better than a non-chip card? If they need to print a signature slip anyway, is there an advantage? Has anyone had experience with this type of card?
Also, how prevalent is the chip-and-pin system in Spain (Madrid and nearby)? We will be renting a car for a day and I'm wondering about automated toll booths or gas stations, especially.
