How to Decode the QR String in Your e-Khata Document (2026 Guide)
If you have received your e-Khata from BBMP or BBSCC and a bank, lawyer, or property registrar has asked you for the QR string, you are not alone. Thousands of Bangalore property owners face the same confusion every year. The QR code printed on your e-Khata contains a digital signature string that most standard QR scanner apps cannot read — and this guide explains exactly what it is, why you need it, and how to extract it in under two minutes.
What Is the e-Khata QR String?
Every e-Khata document issued by BBMP or BBSCC contains one or more QR codes embedded as images in the PDF. Unlike a typical QR code that links to a website, these QR codes store a PKCS#7 digital signature — a cryptographic proof that the document was issued by an authorised government officer.
When decoded, the QR string looks like this:
2933699+++MIIB/AYJKoZIhvcNAQcCoIIB7TCCAekCAQExDzANBglghkgBZQMEAgEF
ADALBgkqhkiG9w0BBwGgggFTMIIBTzCB96ADAgEC...
The string has two parts separated by +++:
- Before +++ — The Khata number (e.g. 2933699)
- After +++ — The Base64-encoded PKCS#7 digital signature of the issuing Revenue Officer
Why Do Banks and Lawyers Ask for the QR String?
When you apply for a home loan, initiate a property sale, or submit documents for mutation, banks and legal professionals need to verify that your e-Khata is authentic. Simply printing or scanning the PDF is not enough — anyone can create a fake PDF.
| Bank / Institution | Why They Need It |
|---|---|
| SBI, HDFC, ICICI, Axis | Home loan document verification |
| Property lawyers | Title verification before sale |
| Sub-registrar office | Mutation and transfer processing |
| BBMP / BDA | Cross-verification of property records |
Why Normal QR Scanners Cannot Read It
This is the most common problem people face. You open Google Lens, a QR scanner app, or WhatsApp camera — and nothing happens. There are three reasons:
- The QR code is very small — Often only 100×100 pixels in the PDF. Standard apps cannot resolve enough detail.
- It is image-based, not vector — The QR is embedded as a compressed image, not a crisp vector graphic.
- The string is very long — PKCS#7 signatures are hundreds of characters, creating extremely dense QR pixel patterns.

What is the QR string in e-Khata?
The QR string is a PKCS#7 digital signature embedded as a QR code in your property document. It starts with your Khata number followed by +++ and a long Base64-encoded signature that proves your document was issued by an authorised government officer.
Why do banks ask for the e-Khata QR string?
Banks require the QR string to verify that your e-Khata is genuine before approving home loans or property transactions. The cryptographic signature in the string proves the document was issued by a real government official with a valid Digital Signature Certificate.
How do I decode the QR code in my e-Khata PDF?
Upload your e-Khata PDF to SalaryBit's e-Khata QR Decoder. Pay ₹49 via UPI or card, and the tool extracts and displays the exact QR string from your document within seconds.
Can I decode the e-Khata QR code for free using Google Lens?
Standard QR scanner apps including Google Lens typically cannot decode the small, dense QR codes in e-Khata PDFs. The codes contain very long PKCS#7 signature strings at low resolution, requiring server-side processing with image upscaling to decode reliably.
Is my e-Khata data safe when I upload it?
Yes. Your PDF is processed in server memory only and is never stored permanently. Once the QR string is extracted and returned to you, the file is immediately deleted. SalaryBit never stores your document or shares it with any third party.
