  • What is online verification of documents?

    Online document verification is a set of procedures that ensures the validity, authenticity, and true ownership of documents provided by users. The document verification process ensures that documents aren’t stolen, forged, expired, or otherwise invalid. This helps businesses to reduce risks of fraud and comply with regulations.

  • What are the types of document verification?

    To verify a user's identity, ID document verification processes government-issued ID cards, passports, driving licenses, residence permits, and more. To verify a user's place of residence, companies use a proof of address verification that processes utility bills, bank statements, and more. Sometimes, companies need to verify the user's money origin. In this case, source of funds verification allows processing of financial, real estate and investment documents.

  • What documents are required for verification?

    To verify a client for KYC (know your customer) purposes, companies usually need to collect the following information at minimum: name, date of birth and address. These requirements are usually covered by ID document checks (sometimes proof of address verification is included). Additional information about customers can be collected depending on the business and regulatory requirements. For example, US businesses may need to verify tax identification numbers of US customers.

  • How does document verification work?

    The document verification process checks for document authenticity and integrity. This usually means checking for the presence of security features and detecting signs of forgery. There are two approaches for document verification: manual and automatic. Due to the rising complexity of methods that fraudsters use for forgeries, businesses switch to automated document verification solutions. This allows them to stay fully protected against fraud and significantly decrease verification time.

  • What are document verification services?

    Document verification services use AI-powered software that detects absence of security features, signs of forgery, graphic editing, and other red flags. In most cases, users simply upload a photo of their document, and the document verification service provider automatically performs document validation and verification. Usually, the required data is extracted, but the verified documents are stored in the system for a certain amount of time so that they can be accessed if needed.
