Faster Than Ever: Our MRZ Scanner Just Got 2x Faster.
At barKoder, we're committed to pushing the boundaries of performance and reliability when it comes to barcode and document scanning. And today, we’re excited to share a major improvement that brings real results to your applications:
Our MRZ (Machine Readable Zone) scanner is now up to 2x faster than before.
Whether you're scanning passports, ID cards, or visas, you'll notice a clear boost in speed and responsiveness — especially on mobile and embedded devices. This performance leap means faster user interactions, smoother workflows, and less time spent waiting for results.
What Is MRZ and Why Does It Matter?
MRZ stands for Machine Readable Zone, and it’s the block of text found at the bottom of documents like:
Passports
National IDs
Visas
Residence permits
These zones contain critical data like document numbers, nationality, name, and date of birth, all encoded in a structured, OCR-readable format.
MRZ scanning needs to be fast, reliable, and error-free, especially in high-throughput environments like airports, government institutions, or mobile verification platforms.
What’s New in Our Latest MRZ Engine?
We’ve made significant internal improvements to the MRZ recognition pipeline, including:
Optimized OCR performance, reducing decoding time by up to 50%
Better handling on lower-end or mobile devices
Improved stability and recognition in variable lighting conditions
Enhanced edge detection and cropping accuracy for MRZ zones
With these upgrades, MRZ scanning in your app feels near-instant—even on devices with modest processing power.
Real-World Results
In our latest tests:
MRZ scan time dropped from an average of 600ms to under 300ms
Success rates remained above 99.5% even in low-light or tilted-camera scenarios
Works seamlessly alongside barcode scanning in multi-mode environments
Whether you’re scanning a single passport or processing dozens per minute, this speed improvement has real-world impact.
How to Get the Update
The improved MRZ scanner is available now in the latest version of the barKoder SDK, including:
Android
iOS
.NET MAUI
