PSD2

Short for Payment Services Directive 2: European Payment Services Directive, which has been implemented in German law since 2018. With the PSD2, various regulations were enacted to increase security in payment transactions and enable more competition between payment institutions. In particular, the requirement for strong customer authentication has been introduced for many forms of cashless payments.
