As of January 2021, the "strong customer authentication" was launched at a pan-European and national level, in accordance with Directive (EU) 2015/2366 "on payment services in the internal market" (PSD 2) and Law 4537/2018 (Government Gazette A' 84). This is a necessary procedure when a consumer carries out payment transactions by card in an e-commerce environment.
The requirements for strong customer authentication constitute an obligation for all payment service providers (e.g. banks, payment institutions, electronic money institutions, etc.), and were set in order to achieve maximum security of customers during transactions effected with the use of payment cards (debit, credit and prepaid).
