Overview & Purpose
The KR420 is a high-performance, full-page passport and ID scanner designed primarily for kiosk or desktop integration. It’s built to read and verify travel documents, offering both OCR (optical character recognition) and RFID capabilities.
Supported Documents
Compliant with ICAO 9303 standards (machine-readable zone) — supports ID-1, ID-2, and ID-3 size documents.
Can read e-passports via RFID (contactless ICs following ISO/IEC 14443 Type A/B).
Also supports a wide range of other documents: visas, driver’s licenses, various ID cards (including non-ICAO standard ones).
Imaging & Light Sources
Multi-spectral imaging: uses visible light and infrared (IR, 850 nm) illumination.
Anti-glare design to reduce reflection from holographic anti-counterfeiting film.
Active scan area: 127 mm × 88 mm.
Sensor: 5-megapixel CMOS (2592 × 1944).
Imaging resolution: 500 DPI, color depth 24 bits/pixel.
Image output formats: JPEG, BMP, PNG.
Can crop a “headshot” photo from the chip’s data for e-passports.
Data Capture & Reading
OCR / MRZ: Reads and extracts text from machine-readable zones as well as other regions.
Barcodes: Supports 1D (e.g., Code 128, Code 39, EAN-13) and 2D (PDF417, QR, DataMatrix).
RFID: Reads and writes to contactless ICs (ISO/IEC 14443 A/B). Supports e-passport Basic Access Control (BAC).
Performance
Scanning speed: less than 1 second per document.
Auto-trigger / Auto-classification: Automatically detects when a document is placed in the scan area, and identifies the type of document.
Communication & Interface
Data interface: USB (USB 2.0 & USB 3.0), PC/SC compatible.
Communication speed: up to 848 kbps.
Indicators & Feedback
Four status LEDs: Power, Ready, Error, Warning.
Sound: includes a buzzer for feedback.
Software / SDK
Comes with a complete OCR SDK: includes DLLs, OCXs, websocket interface, and demo programs.
Programming language support: VC, VB, C#, Java, and includes support for Linux.
Power & Environmental Specs
Power input: AC 100–240 V, 50–60 Hz, 0.8 A; Output: DC 12V, 2A.
Operating temperature: –10 °C to +50 °C; Storage: –20 °C to +50 °C.
Humidity: 20% to 95% non-condensing.
Physical & Mechanical
Dimensions: approx. 193.2 mm × 166 mm × 104.3 mm.
Net weight: ~1.30 kg; Gross weight: ~2.11 kg.
Protection: IP50 rating for dust protection.
Reliability & Application
Built for high-accuracy identity verification in kiosks, desktop devices, airports, banks, etc.
Supports “secondary development” — meaning integrators can build custom applications using the SDK.
Operating Systems
Compatible with Windows (multiple versions) and Linux.
Also supports certain domestic Chinese chip architectures and systems (e.g., Feiteng, Loongson, Kirin, UOS).
Security / Authentication Features
Can verify authenticity of documents via multi-spectral imaging (IR helps check security features).
Support for RFID passive / active authentication for e-passports.
