Today’s financial institutions deal with a lot of paperwork daily, be it invoices, applications for loans, bank and other statements, tax returns, etc. Previously, processing such documents was manual, time-consuming, error-prone, and inefficient. Computer vision is an innovative technology in AI that is revolutionizing how financial documents are processed. It replaces humans, minimizes cost, and increases efficiency. This blog explores how computer vision has been applied to financial document processing, the technologies supporting it, the present uses, benefits, drawbacks, and emerging possibilities. 
What Is Computer Vision?
Computer vision is a division of AI that allows computers to perceive, recognize and understand digital images or videos. Like human vision systems, computer vision systems capture, analyze, synthesize and interpret visual signals to gain knowledge, make decisions and recognize events and objects. In financial document processing, computer vision technologies make machines process financial documents and facilitate the common activities entailing reading the documents to carry out tasks such as data extraction, classification and validation.

Impact: Customers are happy because they do not have to wait long to be approved for loans, and selling these loans is easier.
Bank Statement Analysis
-
Use Case: Financial institutions often use bank statements to evaluate a customer's creditworthiness.
-
Example: Automated processes within artificial intelligence classify transactions as incomes, expenses, and savings, analyze them, and alert them of suspicions such as withdrawals or deposits.
-
Impact: Automating this process improves decision-making efficiency, reduces the chances of making wrong decisions, and is effective in Fraud detection.
Tax Document Automation
-
Challenges: Executive summaries include W-2s, 1099s, corporate tax returns and statements, and other related tax documents, which are usually complex or differ in format, leading to time-consuming and error-prone manual processing.
-
Solution: Organizational software automatically identifies field contents that meet the tax law requirements, applies data validity tests, and arranges the information.
-
Impact: Automation lowers processing time, accuracy and suitability for fueling timely and accurate tax submissions.
Insurance Claims Processing
-
Use Case: Insurance departments manage several documents associated with claims, such as forms, reports, and medical bills, among others, and this information needs to be validated.
-
Solution: Automated information systems help scan such papers, analyze the required points in their letters, notice the differences, and decide which claims are more urgent.
-
Benefit: Claims processed efficiently will automatically result in faster approvals, minimal complaints, reportable incidents, and customer satisfaction.
These applications show how computer vision can revolutionize various financial processes and improve the efficiency and security of business systems, enabling faster services to customers.
