What is an identity document?
An identity document is the most familiar formal expression of personal identity in regulated systems. It allows institutions to anchor a digital application to a legally recognized real-world person. Without such a document, many financial relationships cannot proceed beyond minimal access.
How identity documents work in onboarding
The customer submits the document in person or through a digital flow. The provider checks whether it is genuine, current and consistent with the other information provided. Additional biometric or database checks may then confirm that the document belongs to the applicant.
Why identity documents matter
Identity documents are a foundation of trust in remote finance. They enable KYC, reduce impersonation risk and support secure issuance of cards and access to fiat-related services. For crypto-card products, they are often the first mandatory artifact in the compliance journey.
Types / examples
Examples include passports, national identity cards, residence permits and driver’s licences where accepted. Some jurisdictions or products accept additional forms of government-issued identification.
