1D & 2D Barcode Reading

The MS-E200N supports both conventional linear barcodes and 2D codes.

Manufacturer-listed 2D formats include:

• QR Code
• Data Matrix
• PDF417
• Han Xin Code

Supported 1D formats include:

• Code 128
• Code 39
• Code 93
• Code 11
• EAN-13
• EAN-8
• UPC-A
• UPC-E
• Interleaved 2 of 5
• Industrial 2 of 5
• Matrix 2 of 5
• Standard 2 of 5
• Codabar
• MSI-Plessey
• GS1 DataBar
• GS1 Composite
• ISBN
• UCC/EAN-128

Actual readability depends on code quality, size, contrast, distance, screen brightness and installation conditions.

QR Codes from Phones and Screens

The module is intended to read both paper-based and mobile-screen codes.

This makes it relevant for applications such as:

• Digital entry passes
• Electronic tickets
• Visitor QR codes
• Membership QR codes
• Mobile payment identifiers
• Self-service authentication
• Kiosk transactions

The scanner itself only reads and transmits barcode data. The surrounding access-control, payment or ticketing system determines what happens after the code is read.

13.56 MHz NFC Reader

An important configuration option is the integrated 13.56 MHz contactless NFC/IC card reader.

MASUNG states that the NFC-equipped version supports:

Frequency: 13.56 MHz
Card Interface: Contactless IC card reader
Card Types: Type A / Type B

Some MASUNG documentation also references MIFARE-family and other compatible contactless credentials for particular configurations. Exact card technology should therefore be confirmed before purchase rather than assuming universal NFC/RFID compatibility.

Important NFC Clarification

“NFC reader” does not mean the module will automatically work with every contactless card, access-control credential or mobile-wallet application.

Before ordering, confirm:

• Card frequency
• ISO/card technology
• Type A or Type B requirement
• MIFARE requirement, if applicable
• Required data output
• Host interface
• Access-control controller compatibility

This is particularly important for door access, turnstile and membership systems.

Image Sensor & Reading Performance

Image Sensor: 640 × 480 CMOS

Illumination: White LED, approximately 6500K

1D Minimum Resolution: ≥5 mil

2D Minimum Resolution: ≥7.5 mil

Minimum Symbol Contrast: ≥20%

Viewing Angle: approximately 84° diagonal

Barcode Orientation Tolerance:
Tilt ±60°
Deflection ±55°
Rotation 360°

Motion Tolerance: ≥0.2 m/s according to MASUNG's official parameter table.

I would use these manufacturer-supported values instead of the “300 scans/sec” claim appearing in some reseller listings.

Multiple Communication Interfaces

The MS-E200N platform is designed for integration into different equipment architectures.

Depending on configuration, interfaces include:

• USB
• USB COM
• RS232
• RS485
• TTL
• GPIO
• Wiegand

MASUNG identifies USB and RS232 as standard on one official product description, with RS485, TTL, GPIO and Wiegand available as additional interface options.

Important: Do not assume every interface is simultaneously present on every unit. The exact interface configuration should be confirmed before ordering.

Access Control & Turnstile Applications

The combination of QR/barcode reading, optional NFC and Wiegand/serial communication makes this platform particularly relevant for:

• Access-control terminals
• Turnstiles
• Visitor entry systems
• Membership access
• Attendance/sign-in terminals
• Ticket validation
• Self-service access points

MASUNG specifically markets the MS-E200N family for access-control, turnstile and sign-in applications.

Kiosk & Self-Service Integration

The compact scanner can also be considered for integration into:

• Self-service kiosks
• Vending machines
• Ticketing machines
• Payment terminals
• Check-in stations
• Information terminals
• Embedded scanning panels

Its small physical footprint can help where installation space is limited.

Physical Dimensions

Dimensions: 69 × 55 × 27 mm

Weight: Approximately 35 g

The official MASUNG MS-200N specification lists these dimensions for the compact module.

Some reseller pages show a 42 mm depth for other MS-E200N housing variants, so the exact enclosure should be confirmed against the actual supplied configuration before designing a mounting panel.

That distinction is important for OEM integration.

Power Requirements

MASUNG's official specification lists:

Standard Working Voltage: approximately 3.61–5 V

Optional Wide-Voltage Configuration: 5–16 V

Typical Current: less than 190 mA at 5 V input

Other connector/configuration variants may use different voltage ranges, so confirm the electrical specification before integrating the reader into a controller or kiosk.

Optional OCR Reading

MASUNG lists OCR-A and OCR-B recognition as an optional/customized function.

This should therefore not be presented as standard functionality on every MS-E200N.

Where OCR is required, the specific customized firmware/configuration should be confirmed before ordering.

Environmental Specifications

Manufacturer-listed operating parameters include:

Operating Temperature: -20°C to +60°C

Storage Temperature: -40°C to +70°C

Operating Humidity: 5%–95% RH, non-condensing

Ambient Light: 0–100,000 lux

These figures describe component operating limits and do not by themselves mean the reader is suitable for every outdoor or exposed installation.

Wall-Mount or 86-Box Installation

Some OEM/reseller variants of this module are promoted for installation into 86-type wall boxes/panels.

However, the official core specification I found describes the reader primarily as an embedded scanning module rather than defining every version as a complete wall-mounted finished product.

For that reason, NEOTECH® should use:

“fixed-mount / embedded QR and NFC reader”

as the primary description.

If the exact unit you receive includes an 86-box wall plate or finished wall-mount housing, we can create a separate configuration-specific page or update the page after verifying it physically.

Applications

The MS-E200N may be considered for:

• QR access control
• NFC access control
• Turnstile systems
• Ticket validation
• Visitor management
• Membership systems
• Self-service kiosks
• Vending machines
• Payment terminals
• Attendance systems
• Embedded barcode scanning
• Digital pass scanning
• Mobile-screen QR code reading

The scanner provides identification/data capture. It does not itself provide the complete access-control, payment, vending or ticketing application.

Purpose of Use

The MASUNG MS-E200N is intended for projects requiring a compact reader that can combine:

1D barcode + 2D QR code + optional 13.56 MHz NFC + multiple host interfaces

within an embedded system.

Its value is therefore in integration flexibility rather than functioning as a conventional handheld barcode scanner.

Buyer Guidance

Before ordering, confirm the exact configuration, particularly:

• MS-E200N model/version
• Barcode-only or barcode + NFC
• Required NFC/card technology
• USB / USB COM / RS232 / RS485 / TTL requirement
• GPIO requirement
• Wiegand requirement
• Required operating voltage
• Housing dimensions
• Wall/86-box mounting requirement
• OCR requirement
• Host controller compatibility
• Software/protocol requirements

For access-control projects, confirm these details before placing the order rather than adapting the system after receiving the reader.
