This will be huge. This will allow anyone to accept digital payments, eg. at a farmers market, using the bank accounts everyone already has. The only thing missing is forcing banks to provide an API for third party integrations, but I think there is a separate proposal on the way for that. Imagine being able to accept instant payments from everyone in the EU, without having to sign up for a service like Stripe or Pay…
On the other hand, this is another step towards cashless society, where every transaction is tracked by the government.
Made some stupid comment online while being drunk? We take your ability to by transportation passes/plane tickets...
IIRC this is already happening in China.
