again, my bank threw me under the bus, so to speak.
in the US, there is a magstripe style card (older) and 'chip based' but in the US, the chip based ones are NOT 'chip and pin'. that would actually be somewhat secure. but the US model is the lazy model. its JUST a chip, so its no more secure than the magstripe versions.
when I had a problem with my CC company, they cited that all the purchases were done with 'chip' based cards. they asked me if I had lost my card or ever let it out of my possession. I told them no, I'm the only one who has access to my card and it was never lost or stolen. that was all they needed to claim 'chips are infallable. therefore your fault. pay up!'. I could not believe it!! they had nothing proving it was me (it was not me, I have the court papers showing the criminal gang was doing this to all the locals; it was, in fact, a physical break-in to our mailboxes and had been going on for quite some time. the police caught them and that was the only thing that saved me).
ymmv, but I'm never going to assume that the bank is on my side. the bank is only on the BANKs side. they are not there for you, no matter what they say, publicly.
