Název: Asset Tracking Case Study: Japan Pallet Rental

Anotace: Japan Pallet Rental Corporation enables cost-effective shipment of goods via pallets to customers between Asia and the United States. Most companies lose up to 30% of their pallet stock per year and find the cost of maintaining their stock prohibitive. Japan Rental Company offers the rental of sturdy, reusable plastic pallets at an attractive cost to manufacturers. The RFID solution delivers: •An automated system for easy tracking of pallets on multiple continents •Accurate pallet location information ensuring proper billing for pallet use •A uniquely designed Monza tag antenna for accurate tag reads in harsh environments such as high humidity and extreme temperatures

Popis: The Client Transporting goods via palletizing reduces 90% of the work associated with loading and unloading goods, decreases damage, diminishes quantity errors, and increases storage efficiency. Yet, many companies are reluctant to adopt this method, primarily because of the associated expenses. Using disposable pallets on a large scale is cost prohibitive and has adverse environmental impacts, but reusable pallets require collection when empty, creating additional expense. Japan Pallet Rental Corporation addresses both cost and environmental concerns via their pallet renting business. In 2008, Japan Pallet Rental rented seven million pallets and garnered $159 million in sales. Their strong, reusable pallets circulate in the Asia Pallet Pool system, an alliance of pallet rental companies whose pallets flow between Japan, Korea, China, Taiwan, Thailand, Singapore, the Philippines, Vietnam, and the United States. By using standardized pallets and re circulating them amongst companies in the region, the collection problem is elimi- nated, greatly increasing efficiency. With such a large number of pallets circulating in multiple regions, pallet rental companies often struggle to locate their assets, which detrimentally impacts revenue: •Some companies lose up to 30% of pallet stock per year—a significant drain on profitability, considering a typical plastic pallet costs about $50 •Insufficient knowledge of a pallet’s location makes it difficult to extract accurate payment from customers Although Japan Pallet Rental did not experience such severe losses, they realized that finding a low cost, efficient, item-level pallet tracking method made good business sense. The Challenge Pallets are subjected to harsh conditions. They may be left outside for extended periods, hit or scraped repeatedly by forklifts, or damaged during transport. For these reasons alone, using barcodes to individualize the pallets is impractical, not to mention the additional labor cost such an approach would require. Radio frequency identification (RFID), on the other hand, held great potential. If an could handle the harsh conditions, Japan Pallet Rental could individualize and more easily track their inventory, without incurring high labor costs. To help create an , Japan Pallet Rental turned to Mighty Card. Mighty Card realized that only a rugged, durable tag could withstand the severe climate changes and rough handling conditions. Even when located inside a pallet—where the chance of losing it during normal use was less likely—tags encounter hard treatment. Interior placement limits the location to vertical support walls. These walls, however, also guide the forklift tines, and can be subject to impact. Mighty Card’s first approach was to take a standard RFID inlay and encase it in plastic. But, they discovered that the encapsulation process often damaged and warped the inlays. Creating a recessed well for the inlay did not work either. The thinner coating provided insufficient protection against the forklift tines, which crushed or broke the tag chip. To help solve the problem, Mighty Card approached Impinj. The Solution To create an inlay that would survive the pallet use case, Mighty Card and Impinj turned to a packaged tag chip, which is designed to support direct soldering onto antennas. By using a packaged Monza® tag chip soldered to an antenna, the end result is an inlay that has withstood more stresses than those resulting from the encapsulation process. Creating an accurate, reliable antenna design that met the application read distance requirements proved to be a challenge. For pallet tracking, the antenna had to be carefully engineered to address the effects of the plastic used to encapsulate the tag and the plastic material of the pallet. The tag also needed to be orientation insensitive, because forklifts (which have RFID readers directly attached to them) access pallets from any side. Impinj designers took advantage of the Monza tag chip’s unique dual antenna ports to create a tag antenna that can be read from any direction. Working closely with Mighty Card and Japan Pallet Rental, Impinj engineers designed antenna prototypes, tested, tuned, and re-tested in an iterative process using real pallets for verification. The final antenna design was then encapsulated in plastic and mounted directly onto the pallet. The resulting tag exceeds design specifications. During pre-production testing, Mighty Card put the tag through environmental stresses, including dropping it three meters onto concrete, temperature cycling it from -20 oC to 85 oC, immersing it in water down to 1 meter, and subjecting it to 95% humidity. The tag passed all tests successfully. To test real-world scenarios, forklift operators intentionally hit the forklift tines against a tag affixed to a pallet loaded with 800 kg (about 1700 lbs) of water. The tag continued to work properly, meeting (and exceeding) performance specifications. Even after melting off all the encapsulating plastic (a process that took more than three hours in a 200 oC oven) and cutting the tag in half (leaving the tag chip intact) the tag continued to work. Mighty Card was very pleased to meet their client’s needs with Impinj support. Mighty Card’s rugged tags—readable up to 10 meters distance— will enter full production in the second quarter of 2009. Mighty Card Mighty Card Corporation, a subsidiary of Marubeni Corporation, was established in 1997 to serve the RFID market exclusively. Mighty Card delivers the total RFID solution including tags, readers, middleware, application software, and system integration. Mighty Card has played a part in a number of high profile applications, such as serving as hardware integrator to the Hong Kong Airport. Other major customers include Yodobashi Camera Co., Ltd., the first Japanese company to introduce a substantial UHF Gen 2 RFID system in December of 2005 and Sekisui House, Ltd., the largest home developer in Japan.
