Berliners will soon have to pay fees and other payments to the administration via the payment system Wero. This was decided by the digital committee of the House of Representatives, according to a report by Rundfunk Berlin-Brandenburg (RBB).
Wero – a combination of We and Euro – is a digital payment service that allows money to be transferred by providing a mobile phone number or an email address. It is intended to be positioned against US payment services such as Paypal.
right now afaik wero is part of your regular banking app, so it may be usable just online on your banking website or with custom roms like grapheneos, which a decent amount of banking apps support. there’s definitely a lot of reliance on google and apple though.
