Vancouver Hotel Tracks an Olympic Quantity of Washable Items
The Fairmont Pacific Rim Hotel is using soft rubber RFID tags to manage sheets, uniforms and other laundered assets, reducing labor tracking inventory, lost items and the need for safety stock.
Feb 09, 2010—When the new Fairmont Pacific Rim Hotel opened last week in Vancouver, B.C., just in time for the Winter Olympics, it had technology in place for tracking 35,000 textile items, including bed sheets, uniforms, towels, tablecloths and bathrobes. The system consists of washable EPC Gen 2 passive RFID tags from Fujitsu, RFID interrogators provided by Impinj and software from Foundation Logic, a provider of RFID-enabled linen-management solutions. The hotel is employing the system to track more than 8,500 items weekly as they are laundered and returned.
The Fairmont hotel includes restaurants and several banquet areas that utilize textile tablecloths, as well as 377 guest rooms supplied with bathrobes, sheets and towels. The hotel has limited laundry facilities (sufficient only for staff members' uniforms), so it sends all other soiled items to a commercial laundry in the greater Vancouver area. That means the linens leave the hotel and return only after they are cleaned, pressed and folded, making it that much more difficult to track the items' locations and verify that they all come back.
Most hotels store a large safety stock of linens in the event that some become lost, but the Fairmont, which has a limited amount of storage space, wanted to avoid having to do so. In addition, says Younes Atallah, Fairmont Pacific Rim's director of housekeeping, the hotel wanted to be able to track the number of times each item has been laundered, thereby helping it estimate the lifespan of its linens, based on the number of times they have been cleaned. The company also hopes to eventually receive alerts when an item has been washed the maximum number of times, thus indicating it may need to be replaced.
Fujitsu's WT-A511 RFID tag, designed for applications such as these, is soft and durable enough to withstand washing, drying and dry cleaning, says Dan Dalton, the company's director of new product development. The tag, which has a read range of 6 feet, makes an application like this possible, says Marvin Tulman, Foundation Logic's founder and CEO. The WT-A511 tag, made with Fujitsu RFID chip, has been tested at up to 85 degrees Celsius (185 degrees Fahrenheit) in washers (it can last for more than 200 washings) and 120 degrees Celsius (248 degrees Fahrenheit) in driers, and in ironing systems that reach 200 degrees Celsius (392 degrees Fahrenheit).
The RFID tags previously used by Foundation Logic had a much shorter read range, the company reports, and therefore required users to hand-read each item. With the system that the Fairmont has adopted, Tulman says, an interrogator can read as many as 500 WT-A511 tags simultaneously. By reading the tags as a basket of laundry is rolled through a portal, the hotel can track all of its high-value laundered items that would otherwise have been too time-consuming to scan individually each time they were washed.
The tags are attached to high-value items (face cloths and napkins were not included). To accomplish this, the hotel devised a small fabric patch that resembles a clothing label, with the Fairmont's logo on the front, sewn onto the items by the hotel's seamstresses. Inside each patch is an RFID tag encoded with a unique ID number, up to 96 bits in size. When installing the system this winter, Foundation Logic's staff first read each tag to register its ID number in the software the linen-management solutions firm provided, and input the type of item it was—such as a robe, sheet or tablecloth—along with the date. In the future, however, Fairmont's workers will handle that task.
