The process of determining whether a document, such as a bank statement, job record, business document, etc., is authentic or not is known as document verification. Many companies use document verification in conjunction with other methods of identity verification as part of their overall identity verification procedures. The word “document verification” is most frequently used to refer to online or digital document verification, though it can take place in both physical and digital places. Online document verification involves document collection, data extraction, document validation and manual verification.
