Personally, I like cash. Better for tips, pocket money and other things. I also like to not leave any transaction history, even if banks are mostly privacy aware.
If you are dependent on social security and the state has the power to look through your finances, you begin to see the advantages again. Because they would rob you of your last 20$.
Cashless paying is convenient and fast, but otherwise isn't really something many people strive for.
Heard about the finance crisis in Greece and how access to their bank accounts became restricted? Another hint.
I'm from the US and I've had my chip based Visa pin debit card declined in France due to network incompatibility that neither side could figure out (at a McDonalds of all places) - the authorization just wasn't making it to the issuer.
Basically the further you get from you issuing bank's region/network, the more likely you are to run into problems, regardless of what country you're in. In the US because payment processing industry is so big, merchants are more likely to accept more networks than in other countries because they're paying more to support it or have negotiated better rates with middle men like FDC or directly with Visa/MC.
I think in Germany most MC is actually run using the Maestro network and merchants get hit with either per transaction fees or high interchange rates for using non-maestro cards (if they even opt-in for that with their acquirer).
I know of instances where a credit card from Amsterdam, the Netherlands is not even accepted at a shop in the Swabia region of Germany.
I also know of instances where they outright refuse to accept Visa and only deal with Mastercard and such - that too issued in Germany!!. What's the point of a credit card if you cannot travel with it?
Why are cash transactions so much more prevalent in Europe? I've seen the same in Japan but that's entirely a different case.
