attention that when using a credit card without a chip a merchant will routinely ask for your passport. Also that it needs to be original passport. I really have no intention of doing anything different in Spain than I would anywhere else which is carry only a photocopy of my passport. Anyone else run across this when using Visa credit card from US? Just called my bank that issued my card and they are doing some "trials" for chip cards but they are simply not available to most card holders at this time. Interesting.
