RFID Linen Management at Marriott: A Chainway MC51 Case Study

Challenges in Hotel Linen Management

Common issues in hotel linen operations include:

• Time-consuming counting and frequent manual errors: High volumes and multiple SKUs make manual stocktaking inefficient and prone to missing items.
• Complicated housekeeping records: After room cleaning, staff must manually record and compile reports, which is labor-intensive and not real-time.
• Limited transparency in collection and outbound handover: Discrepancies often occur between physical counts and records across collection, staging, and outbound handover.
• Warehouse stocktaking burden: Long inventory checks make frequent cycle counts impractical and reduce inventory accuracy.

•  RFID Tagging (Item-Level Identification)
  Washable RFID tags are sewn into linens such as bed sheets, towels, and bathrobes. Each item carries a unique RFID ID and can be tracked and analyzed by category, status, and location

• Key Operational Processes Inside the Hotel
  The solution covers the following major operational steps:

•  Clean Linen Inbound Scanning (Receiving / Shelving)
  When clean linens arrive, staff use the MC51 built-in UHF handheld to scan linen carts or baskets in bulk. The system automatically records inbound receipt.​

• Housekeeping Scanning (Issuing / Usage Confirmation)
  During housekeeping operations, staff scan linens with the MC51 to associate linen usage with specific floors or tasks, reducing manual recordkeeping.

•  Dirty Linen Outbound Scanning (Collection / Outbound Handover)
  After dirty linens are collected and consolidated, staff perform bulk verification with MC51 before outbound handover. The system automatically summarizes quantities and categories, generating accurate outbound records and handover evidence.​
