In reply to Dan Martin.

Dan, thanks for your comment. For sure, you´re right. Indeed, I myself like to have plastic cards in my wallet - and still like to use it. But more or less it is based on not having any advantage in using e.g. my smartphone. All payment methods which are smartphone based (in Germany e.g. Yapital and PayPal) are much too complex and take too long reading a QR-code and confirming the transaction online... this brings me to another point: At least in Supermarkets I personally do have the problem or poor internet access - no wonder, as the shelfs and the rooftop are metal based and work like a Faraday´s cage... So how shall I confirm the transaction online using "my" smartphone´s internet connection...
So - sure a lot to come over the next years. But as said: As long the new payment methods at the Point of Sale aren´t faster and/or easier as using a plastic card... I don´t see any chance for them
