Introduction: One Compact Module, Two Essential Functions
In today’s self-service and access control industry, engineers often struggle with limited space while needing both a barcode scanner and an NFC card reader. Two separate modules mean more wiring, higher costs, and complex integration.
Totinfo’s embedded QR code + NFC module solves this challenge by combining both functions into one compact device. With just one interface, your kiosk, access terminal, or smart locker can scan barcodes and read contactless cards seamlessly.
1. The Design Challenge
OEM designers frequently encounter the following issues when developing kiosks or access panels:
Limited housing space for multiple components
Complicated wiring between controllers and peripheral modules
Firmware integration difficulties between barcode and NFC readers
Increased maintenance and debugging workload
Totinfo’s E230N, E200N, E260N, and DCS20N dual-function modules offer an all-in-one plug-and-play solution that simplifies system architecture while reducing both cost and complexity.
2. High-Performance Scanning Capability
Equipped with advanced CMOS image sensors, these modules quickly and accurately decode printed and on-screen barcodes, supporting QR Code, PDF417, Data Matrix, EAN/UPC, and more.
They perform reliably in various environments—from indoor kiosks to outdoor smart lockers—offering:
Fast decoding with wide field of view
Hands-free operation with high accuracy
Compact structure ideal for space-limited applications
3. NFC Integration for a Contactless Experience
Beyond barcode scanning, the module also supports 13.56 MHz NFC card reading, fully compliant with ISO 14443 A/B and FeliCa standards. It’s compatible with MIFARE Classic, Ultralight C, Desfire, and even smartphone NFC tags.
Users can easily access or make payments either by scanning a QR code or tapping an NFC card — no need for separate readers or extra hardware costs.
4. Designed for OEM Flexibility
The module features multiple interface options, including USB, TTL, RS-232, RS-485, and Wiegand, ensuring easy integration with various controllers.
Built-in LED indicators and buzzer feedback enhance user interaction, while its compact form and 360° scan angle make it ideal for wall-mounted terminals or small vending devices.
5. Typical Application Scenarios
Access control systems: Authenticate users via QR code or NFC employee badge.
Smart parcel lockers: Scan or tap to identify and retrieve packages.
Retail kiosks: Read membership QR codes or NFC loyalty cards.
Vending machines: Enable cashless purchases via mobile QR or NFC payment.
Conclusion: Simplify Design, Enhance Experience
With Totinfo’s dual-function QR code + NFC modules, OEMs no longer need to choose between barcode and contactless solutions. Models like E230N, E200N, E260N, and DCS20N integrate both technologies into one reliable, compact unit—reducing design complexity and improving end-user convenience.
If you’re developing self-service terminals, access control devices, or smart lockers that demand efficiency and reliability, Totinfo’s modules offer the ultimate integration solution.
