You usually can turn it off I think. One of my colleagues' greeting states that you should _not_ leave a message, followed by 2 minutes of silence, to put off all but the most committed.
> [A]n identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.
I think the principle is that since an IP address could be used to identify you, it is considered personal data.
Well, if you look in the options you'll find Firefox actually does have an option whether to accept all cookies, only first party, no cookies or always ask. Chrome also has an option to deny all cookies, third party cookies or accept all (no ask here).
It means it will accept cookies for other domains if you have visited the other domain explicitly before. This makes things like embedded widgets work.
Plus, you still have to support plaintext between the EMV chip and the reader. This opens an entirely new class of places to steal card details (like PINs)
One reason for this is that it's at the discretion of the issuing bank whether or not to accept an expired card (in fact, you can get into trouble for handling this locally with some processors).
I believe it's a convenience thing for the end user, when issuing a new card - offer a couple of days "grace" - and arguably there isn't much risk associated with this practice: lost/stolen cards are always cancelled immediately.

Similar to klodolph - it's very common in the UK for each dwelling in a shared building to have its own supply, termination point and meter for both electricity and gas.
