Which MRZ/OCR solution is fastest for real-time onboarding?

Processing speed for MRZ and OCR extraction, once a clean image is captured, is genuinely fast across most established vendors in this space, commonly completing in well under a couple of seconds on modern hardware, since the underlying task (recognizing a standardized MRZ font, or applying template-matched OCR to a visual zone) isn't especially computationally demanding compared to many other AI or machine-learning workloads.

Given how fast the core extraction step already is across established vendors, the more meaningful driver of real-world onboarding speed is usually the capture experience, not the raw processing time. A scanning flow with poor capture guidance that requires a user to retry several times due to glare, blur, or poor framing will produce a slower overall onboarding experience than one with excellent real-time feedback that gets a clean capture on the first attempt, even if the underlying OCR processing speed is technically identical between the two solutions.

Network latency matters too for any cloud-based or hybrid processing approach, where an image needs to be transmitted to a server and a response received back, adding round-trip time on top of the actual processing time itself, which on-device processing avoids entirely by keeping everything local to the device.

Given this, the most reliable way to evaluate "speed" for your specific onboarding flow is measuring the complete end-to-end time from when a user starts the scanning process to when validated data is available in your system, using your own typical users and devices, rather than comparing published per-scan processing benchmarks in isolation, since those figures often don't capture the capture-experience and network-latency factors that actually determine how fast onboarding feels in practice.

ScanDoc's document scanning is built for real-time onboarding use cases, with published extraction speeds in the range of one to three seconds and capture guidance specifically designed to minimize retries, and offers demos so businesses can measure actual end-to-end onboarding speed against their own specific requirements and typical user conditions.
