RETAIL | ASIA | BARCODE + UHF RFID H&M Checkout Transformation with Chainway SR160 RFID Scanner

Background

• As one of the world’s leading fast-fashion brands, H&M manages an enormous flow of apparel items across thousands of stores globally. To maintain high turnover speed and seamless customer experiences, its store operations rely heavily on fast, accurate checkout performance and precise inventory visibility.
• In recent years, H&M has embarked on a gradual transition toward RFID-enabled retailing, introducing UHF RFID tags to improve supply chain traceability and checkout automation. However, during this transition, stores still handle a mix of RFID-tagged and barcode-only items — creating a complex dual environment at the checkout counter.
• The key challenge was how to integrate RFID efficiency without disrupting existing POS systems or retraining cashiers extensively. H&M needed a single, unified scanning solution capable of reading both RFID tags and barcodes efficiently within one workflow.

Challenge

H&M’s retail operation identified three critical challenges:

• Hybrid Item Environments — Some items are equipped with UHF RFID tags, while others still use conventional barcodes, requiring two different scanning devices.
• Checkout Congestion — Manual barcode scanning slows down transactions during peak hours and increases queue times.
• Continuity and Reliability — RFID tags may occasionally be damaged or unreadable; relying solely on RFID readers risks transaction interruptions.

To solve these issues, H&M required a hybrid device that seamlessly switches between RFID and barcode modes, ensuring speed, redundancy, and reliability.

Solution

H&M selected the Chainway SR160 UHF RFID Scanner, an advanced handheld device designed specifically for hybrid retail environments.
The SR160 combines high-speed UHF RFID reading with 1D/2D barcode scanning in a single ergonomic form factor. Built with Chainway’s self-developed UHF module based on the Impinj E310 chip, SR160 supports the Impinj Gen2X protocol, offering rapid and accurate tag reading within an adjustable range of 7 cm to 100 cm.
At H&M’s checkout counters, the SR160 is connected to POS terminals through USB or Bluetooth. Store staff use it to perform dual-mode scanning:

• Primary Mode: RFID Checkout
  Most H&M apparel is embedded with UHF RFID tags. Cashiers place items within the SR160’s sensing range, and the reader instantly detects all tags, transmitting the product data to the POS for billing within seconds.
  This process eliminates manual scanning and significantly reduces customer waiting time. 
• Backup Mode: Barcode Scanning
  In rare cases where RFID tags are damaged, unreadable, or missing, the SR160 automatically switches to barcode mode. The cashier can quickly scan the printed barcode label, ensuring transaction continuity and zero item omission.

This dual-mode design eliminates the need for separate devices and ensures operational reliability even during the RFID rollout phase.

Technical Highlights

• Dual-Technology Integration – Combines RFID (UHF) and 1D/2D barcode scanning in one device.
• High Reading Sensitivity – Impinj E310-based module delivers stable performance across varying tag densities.
• Adjustable Range (7 – 100 cm) – Optimized for close-to-medium range checkout scenarios.
• Seamless Connectivity – Supports USB, RS-232, and Bluetooth; integrates easily with H&M’s POS ecosystem.
• Cross-Platform Compatibility – Works with Windows, Linux, and macOS, ensuring flexible deployment.
• Ergonomic Design – Lightweight structure minimizes cashier fatigue during continuous operation.

Implementation and Workflow

During pilot deployment, H&M integrated SR160 devices at selected high-volume stores.
Each checkout counter was equipped with one SR160 connected to the existing POS system.
When scanning, the cashier’s workflow was simplified to two intuitive steps:

1. Place all RFID-tagged items near the scanner for automatic identification.
2. If any item fails to register, scan its barcode manually with the same device.

No extra hardware or process change was required. The POS system automatically received unified data, updating sales and inventory databases in real time.

Results

After several months of operation, the results were clear and measurable:

• Checkout time reduced by up to 80% compared with barcode-only systems.
• Error rate (missed or duplicated scans) decreased by over 70%.
• Hardware footprint reduced — one SR160 replaced two separate scanners.
• Staff efficiency improved — less device switching, fewer keystrokes.
• Customer satisfaction scores increased due to faster and smoother checkout.

Moreover, the data consistency between sales and inventory systems improved significantly. The unified data flow from both RFID and barcode sources allowed H&M’s backend systems to maintain real-time stock visibility, supporting better replenishment decisions.

Impact

The H&M deployment of Chainway’s SR160 showcases how hybrid RFID and barcode scanning can deliver tangible business value during the transition toward fully RFID-enabled retail.
By enabling “RFID-first, barcode-backup” workflows, H&M achieved both innovation and continuity — boosting checkout speed without compromising accuracy or reliability.
This approach illustrates the flexibility of Chainway’s technology: rather than forcing disruptive change, SR160 provides an evolutionary path from barcode-based retailing to RFID-powered operations.
The project demonstrates Chainway’s core philosophy — combining precision, flexibility, and stability to help retailers worldwide move confidently into the era of intelligent retail.
