Youku M2 Red Light Barcode Scanner for Alipay, WeChat, and Payment Codes – USB or Serial Port

The Youku M2 is a handheld 1D barcode scanner designed to read payment codes and product barcodes quickly and reliably. Using a visible red light source (632nm ± 3nm), it achieves a scan speed of 120 times per second – fast enough for busy retail checkouts, ticketing desks, or service counters. It works with Alipay, WeChat Pay, and image-based payment codes, and supports multiple interface types including USB, serial port, and USB virtual serial port. The scanner is built to withstand daily use in demanding environments, with IP54 dust and water resistance and the ability to survive a 2-metre drop. Its operating range covers -20°C to 60°C and up to 10,000 LUX ambient light, so it performs reliably under typical indoor and covered outdoor conditions.

Features and Construction

The Youku M2 combines fast scanning with practical durability. Its red light engine reads standard 1D barcodes at high speed, while the housing and electronics are rated for industrial hygiene and impact resistance.

Scan Performance and Speed

With a scan rate of 120 times per second and a minimum contrast requirement of just 25% reflection difference, the scanner reads most printed and on-screen 1D codes accurately. The visible red light source (632nm ± 3nm) offers good visibility of the scan line, helping users align the scanner correctly. Ambient light tolerance up to 10,000 LUX means it works under bright shop lights or direct sunlight indoors.

Interface Options

The scanner offers three interface choices: USB (for direct plug-and-play with most POS systems), serial port (for legacy or specialised equipment), and USB virtual serial port (for compatibility with software expecting a serial connection). This flexibility makes it easy to integrate into existing checkout or inventory setups without additional converters.

Durability and Rating

Rated to IP54, the scanner is protected against dust ingress and water splashes from any direction. It can survive a 2-metre free fall onto a hard surface – a practical safeguard for busy environments where drops are common. The operating temperature range of -20°C to 60°C and storage range of -40°C to 85°C ensure reliable function across seasons and climates.

Uses and Placement

The Youku M2 is designed for environments where fast, accurate barcode reading is essential – from retail tills to warehouse receiving areas. Its compact shape and multiple interface options suit both fixed and mobile scanning positions.

Retail and Payment Scanning

In shops, cafes, and service points, the scanner handles payment code scanning for Alipay and WeChat Pay as well as standard product barcodes. The red/blue bi-colour LED and buzzer give clear audible and visual confirmation of a successful decode, reducing errors and speeding up transactions. The tone of the buzzer can be customised to suit operator preference.

Inventory and Stock Control

For warehouse or back-office use, the 120 scans-per-second rate reduces time spent scanning batches of items. The IP54 rating means it can handle dustier environments, and the 2-metre drop tolerance gives peace of mind if the scanner is knocked off a shelf or workbench.

Benefits and Buying Value

Choosing the Youku M2 means getting a reliable, everyday workhorse scanner that balances speed, durability, and interface flexibility. It avoids the need for multiple specialised devices and offers straightforward setup.

Low Maintenance and Reusable

With no consumables to replace and a robust build, the scanner requires minimal upkeep. Cleaning the scan window occasionally with a soft, dry cloth is usually sufficient. The IP54 sealing reduces the risk of internal damage from dust or light moisture, prolonging service life in typical retail or office conditions.

Why Choose This Product

The Youku M2 stands out for its combination of high scan speed, broad ambient light tolerance, and genuine drop protection, all at an accessible price point. Its multiple interface options make it compatible with a wide range of POS and inventory systems, while the IP54 rating and CE & FCC compliance ensure it meets regulatory and durability standards for commercial use.
