Banks and financial service providers are obligated to carry out legitimacy checks for any natural or legal entity within the framework of compliance regulations and regulatory requirements (GDPR, PSD2, BCBS 239 and 5th EU Anti-Money Laundering Directive).
Failure to comply with identity verification can result in customers committing (chargeback) fraud and money laundering. In addition, ignoring money laundering, KYC (Know Your Customer) and AML (Anti-Money Laundering) guidelines is a serious violation of legal requirements.
The only way to protect yourself against financial damage and legal consequences, while still maintaining the trust of your customers, is to comply with these regulations and carefully check all potential clients.
