good development of the payment but it was convenient few years ago. I still don't get why they don't implement the Payment system into a "digital Fahrschein" without buying a paper ticket.
Best transit system I've ever used was the underground in London. No Ticket, no "Insellösung" simply using your CC to check-in/check-out.
Still don't get why whey are not going this ways. Maybe the problem is the giro card that seems not able to generate tokens. btw: NYC will follow the London style transit with NFC payments. If we see the development in Germany maybe 2028 we are able to use this way of transit while the whole world is using face detection to pay
Oh perhaps some are suffering a GiroCard persecution complex, who knows?
There are reservations against such a solution in Germany because of data protection and profiling reasons. there should start a pilot test in Nürnberg where NFC cards were used to check in and check out of bus, subway, tram etc. - the result was a massive backlash because data protection activists and customers complained about the possibility to generate a mobility profile:
Who gets when and where on what line, who steps where and when out of the lines? what is around these points, who takes the same lines, who meets who regularly on what spots, etc.
that will be the main reason, why (afaik) no transport authority in Germany established such a system.
I remember to check in carparks in LB/S with my MasterCard around 2000/2001. Read the CC at the entrance and read the CC at the exit ... automatic charge of the correct amount. no need to get to a vendor with a ticket. was shut down about a year ago, same arguments "the company knows what car when and blah..." did not see this system a lot in the last 20 years. could count it on two hands...
