OCR in banking: what it means, where banks use it and how it works

For bank operations, lending and compliance teams. See what OCR does with banking documents, where it saves the most retyping and how to roll it out one process at a time.

Key takeaways

  • OCR in banking is optical character recognition software that reads the text on checks, statements, IDs and loan applications and turns it into data.
  • Banks use OCR wherever staff would otherwise retype a document. The main uses are loan processing, account opening and KYC, check processing, statement review, compliance records and archive digitization.
  • OCR alone gives you only text. Intelligent document processing (IDP) also sorts the documents, pulls out each field and checks it. Staff then review only the values the software flags, instead of retyping.
  • Roll it out one high-volume process at a time, and test on your worst scans and phone photos before you expand.

OCR in banking is software that reads the text on bank documents and turns it into data. Core banking systems and loan platforms can use that data. Banks use it wherever staff would otherwise retype a document, from loan files to check images. OCR stands for optical character recognition, and on its own it returns text. IDP, or intelligent document processing, also sorts the documents, pulls out each field and checks it. Staff then review exceptions instead of typing. An exception is a value the software flags for review.

Common OCR use cases in banking#

These are the places banks use OCR, and what it reads in each one.

  • Loan processing

    Applications, pay stubs, tax returns and bank statements are read and checked against each other, so underwriters start from data. See loan document automation.
  • Account opening and KYC

    A US bank must get at least a name, date of birth, address and ID number before opening an account. It must also verify the customer's identity, for example with a driver's license or passport. OCR reads the ID and proof of address, so staff check the data instead of typing it. See automated KYC verification.
  • Check processing

    US check payments still numbered 9.2 billion in 2024. OCR reads the payee, amount, date and check number from each check image, including mobile deposit photos. See check OCR.
  • Bank statements

    Every transaction and balance is extracted, tables that run across pages are joined, and running balances are checked. See bank statement extraction.
  • Compliance records

    Records required under the Bank Secrecy Act must be kept for 5 years and be accessible within a reasonable time. OCR indexes them, and redaction hides account numbers before a file is shared. See automated redaction.
  • Archive digitization

    Old loan files and signature cards become searchable text, so staff stop pulling boxes from storage. See what OCR is.

How OCR works in a bank#

OCR technology turns a page image into characters and does nothing more. To be useful to a bank, the characters have to become fields, such as the check amount, the account number or each statement row. Those fields then have to be checked before they post.

How a bank document becomes data

The software recalculates totals, checks that required fields are filled in and compares values with the application or the account record. It sends anything it isn't sure about to a person before that value goes into your system.

Benefits of OCR for banking#

OCR helps most when it removes retyping and the mistakes that retyping causes.

Manual document handling

  • Back-office staff key amounts and account numbers from scans
  • An application waits while its documents move from desk to desk
  • A mistyped account number turns up later as an exception
  • Finding an old record means pulling a box from storage

OCR with extraction and checks

  • Fields post to the core banking or loan system without retyping
  • Values are checked, and uncertain ones go to a person first
  • Each value links back to its place on the page
  • Records are searchable by name, date or account number

In live use, Docsumo reports these results. Field-level accuracy is the share of extracted values that are right.

  • 99%field-level accuracy across 250+ document types
  • 95%+of documents processed straight through, without manual review
  • $15saved per processed document

National Debt Relief, a debt settlement company, reads creditors' settlement letters with Docsumo and processes 95% of them straight through. See the case study.

How to implement OCR in banking#

  1. Pick one high-volume processChoose loan intake, account opening or statement review, wherever staff retype the most.
  2. Collect real samplesInclude faxes, phone photos, handwritten forms and multi-page statements as well as clean PDFs.
  3. Test OCR that extracts and checksMeasure field-level accuracy on your samples. Also test tables that continue across pages, handwriting, confidence scores and the API.
  4. Connect it to your systemsMap fields to the core banking system, loan origination system or CRM, and test in a sandbox before go-live.
  5. Run a trial, then expandRun the same files by hand and with the software. Compare accuracy, the share of documents that go straight through without review, and how long each file takes from start to finish. Then add the next document type.

Docsumo is an intelligent document processing platform. Its OCR software reads printed and handwritten text and joins tables that run across pages. It checks running balances on bank statements and sends low-confidence fields to your own reviewers. On the Business plan, Docsumo can classify documents and split mixed packets. A mixed packet is a single file that holds several kinds of document. On the Enterprise plan, Docsumo can check values across the documents in a file. Docsumo sends data to your systems through API and webhooks or as an Excel download. API and webhooks pass data between systems automatically. Docsumo runs in the cloud only. It isn't a desktop tool for editing PDFs or making searchable files. If all you need is to scan an archive, a scanning tool is the better fit.

Who checks the fields your bank's OCR isn't sure about?#

We'd keep the review of uncertain fields with your own staff. Buy software your team runs, not a service whose staff review your files for you. That way you keep control of the process and of what it costs. Docsumo supplies the software, and low-confidence fields go to your own reviewers.

Reading the characters is the easy part. The value comes from pulling out the right fields, checking them and sending only the doubtful ones to a person. So start with one process, and test on your hardest documents.

Frequently asked questions#

What does OCR stand for in banking?

OCR stands for optical character recognition. In banking, it means software that reads the printed or handwritten characters in a scan, photo or PDF. It turns them into text a computer can use, so staff don't retype data from checks, statements, IDs or loan documents.

What's the difference between OCR and IDP in banking?

OCR reads the characters on a page. Intelligent document processing (IDP) also works out what each document is and extracts named fields, such as the account number or ending balance. It then checks them and sends uncertain values to a person. See IDP vs OCR.

What is OCR in KYC?

KYC stands for know your customer. It is how a bank confirms who its customer is. In KYC, OCR reads the name, date of birth, address and document number from a driver's license or passport. It also reads the address from a utility bill or bank statement. Staff don't have to type these values, and the software can match them to the application. A separate step uses ID verification tools to check that the ID is genuine and belongs to the person applying.

Can OCR read handwritten bank forms?

Modern OCR reads handwriting, but less reliably than print, so values it isn't sure about should go to a person. Docsumo reads handwritten text and sends low-confidence fields to your own reviewers, and clicking a field highlights where it sits on the page.

Is OCR secure enough for bank documents?

That depends on the software you use with it. Ask the vendor for its SOC 2 Type 2 report. Ask whether it has encryption, role-based access and audit logs. Ask for a clear answer on whether your documents are used to train AI models that other customers share. Docsumo is SOC 2 Type 2, HIPAA and GDPR compliant and ISO/IEC 27001:2022 certified. Your documents aren't used to train shared or third-party models. See security.
