In modern BFSI apps, faster customer onboarding speed has become a major priority, making intelligent document scanning and verification essential from the very first user interaction.
If your app simply needs to generate statements or forms, a PDF library can get the job done. But if you want to read and verify customer documents on the fly, an AI document scanning SDK is often the real game-changer.
In fact, many BFSI mobile apps now rely on intelligent scanning from the very first user interaction.
BFSI Document Workflows and Automation
Financial institutions handle mountains of paper – from loan applications to insurance claims and e-statements.
In today’s data-driven environment, documents remain one of the most critical sources of business information, and the ability to extract, verify, and act on that data directly impacts operational speed, accuracy, and security.
Manual entry is no longer acceptable because it slows onboarding, increases processing errors, and creates inefficiencies across enterprise workflows.
Banks and insurers often tie their mobile apps into workflow automation software, connecting front-end capture to back-end processes. For example, one provider notes that clients use automation to cut KYC and document verification time by 70% while ensuring “100% compliance”. In practice, this means mobile captures (like scans of IDs and bills) feed directly into automated KYC/AML checks and approval routes.
The real question becomes whether to rely on static document tools or intelligent capture systems.
The short answer is, you usually need both – but for intake and onboarding, AI scanning is increasingly indispensable, while PDFs handle structured output workflows.
AI Scanning SDKs: Intelligent Document Capture
Mobile apps are increasingly capture-first. To scan an ID or bill, they use specialized SDKs that combine camera guidance, OCR, and AI. A basic step is often an OCR SDK for mobile apps, which converts an image to text. But in banking use-cases, raw OCR is just the start. These tools need to work reliably on-device and handle everything from dark corner scans to crooked angles.
That’s why modern platforms rely on intelligent scanning and digital capture solutions that:
- Detects edges
- Fixes perspective
- Improves lighting
- Auto-crops images
Once captured, a document scanning SDK for mobile apps classifies documents and extracts structured fields.
This works like a data extraction SDK, pulling:
- Names
- ID numbers
- Dates
- Addresses
Modern systems also use mobile scanning SDK technology for fast, on-device processing, improving both speed and privacy.
Behind the scenes, these AI scanning SDKs tie into larger systems. Captured data often flows into intelligent document processing software on the backend, which applies business rules and cross-document checks.
And the final images and parsed data get stored in a secure document management software system for audit trails. In short, an AI scanning SDK is the front-line for capture and verification, feeding verified data straight into the bank’s automated workflows and archives.
PDF Libraries: Static Document Generation
PDF libraries (like iText, PDFTron, PSPDFKit, etc.) are powerhouse SDKs for creating and manipulating documents.
In BFSI apps, they are used for:
- Statements
- Receipts
- Invoices
- Legal forms
For example, India’s PayNearby used the iText 7 PDF library on its server to generate all customer invoices and receipts. The CTO reports they now produce “4–5 million documents annually” with iText at the core.
These libraries are strong in:
- Layout control
- Digital signatures
- Compliance formatting
They often come with PDF viewing/editing components for mobile: indeed, some apps embed a PDF SDK for mobile apps so users can view or annotate their statements offline. Teams choose these libraries for their maturity and compliance certifications.
However, PDF tools only work when data already exists in a structured form. They do not interpret images, verify live user input, or support intelligent onboarding workflows.
For onboarding, fraud checks, and live verification, PDF libraries alone are not enough because they cannot independently validate customer authenticity or detect document tampering during onboarding processes.
Comparing the Approaches
The table below summarizes the key differences between using a PDF library and an AI scanning SDK in a BFSI mobile app:
| Aspect | PDF Libraries (e.g., iText, PDFTron) | AI Scanning SDKs (e.g, Onfido/Entrust, Microblink) |
| Primary Role | Generate and edit static documents (statements, receipts, forms). | Capture and interpret user documents (IDs, bills, forms). |
| Function | Output-oriented: Lays out text/images you provide. | Input-oriented: Reads camera images & returns structured data. |
| Compliance Support | Limited | Built-in KYC/AML validation |
| Data Extraction | Minimal/OCR add-ons only (pdfOCR). Not for free-form images. | Built-in OCR + AI extraction: fields, tables, handwriting, barcodes. |
| Real-time User Flow | No camera guidance. Serves completed PDFs (viewers for display). | Guides camera (auto-crop, feedback) and processes instantly on-device. |
| Fraud/Integrity Checks | Signatures, encryption for storage (PDF security features). | Document authenticity and liveness checks (fraud signals, deepfake detection). |
| Device vs. Server | Usually, with every side generation, the client can use the viewer. | Typically, on-device processing (edge AI) for speed & privacy. |
| Integration | Embedded in app or backend (requires developer coding PDF templates, forms). | Mobile SDK with plug-and-play capture screens and validation UI. |
| BFSI Use Cases | Statements, invoices, regulatory reports, e-sign forms, and loan docs. | KYC onboarding (ID verification, utility bills), remote deposits, and compliance checks. |
Above all, a PDF library and an AI scanning SDK serve different layers of the document workflow. PDF libraries are essential for formatting and output – they excel when you already have the data and need a polished document. AI scanning SDKs, by contrast, are the engines that pull data into your system from customer-provided images. In banking terms, one builds the paperwork; the other reads the paperwork.
Real-World Applications of AI and Document Technologies in BFSI
BFSI organizations don’t use these tools in isolation—they solve different operational problems.
