University of Parma’s RFID Lab Launches Test Program for Apparel

By Claire Swedberg

The "RFID 4 fashion certified" initiative is intended to determine how well EPC Gen 2 UHF RFID readers, tags and printer-encoders perform in real-world use cases for Europe's garment industry.

Over the next week, the RFID Lab at the University of Parma's Department of Industrial Engineering, in Italy, will begin testing the performance of various makes and models of EPC Gen 2 ultrahigh-frequency (UHF) RFID hardware for use by European apparel retailers and manufacturers. The program, known as "RFID 4 fashion certified," is intended to determine how well the hardware performs in real-life use cases.

Once testing of a specific piece of RFID equipment—a tag, an inlay, a fixed or handheld reader, or a printer-encoder—is complete, the laboratory will present the maker of that equipment with a certificate indicating its product has undergone testing for fashion applications. Then, if the technology vendor authorizes the lab to do so, the results will be made available to businesses that manufacture, transport or sell fashion in Europe, so that they can determine how well the technology will perform in their particular applications.

The University of Parma lab is carrying out the program at the request of the lab's Board of Fashion Advisors—a group consisting of 13 companies in the apparel industry, including Benetton, Gucci, Max Mara Fashion Group, and Miroglio Fashion. The board members and the lab have worked together since 2008, studying RFID technology's benefits (see RFID Boosts Store Turnover by Nearly 10 Percent in Italian Pilot, Fashion Group Expects Positive ROI Within 3 Years and Italian RFID Lab Gets Fashion-Forward). Over that span of time, says Antonio Rizzi, the lab's head and founder, many questions that companies have asked of the lab's researchers have pertained to how a specific piece of hardware—such as an inlay, reader or printer—performed, or which hardware would be the best choice for a company's specific application, such as logistics, inventory checking or store security.

The University of Arkansas' RFID Research Center has also been testing RFID hardware performance, at its Arkansas Radio Compliance Center (see Arkansas Radio Compliance Center Aims to Avert Clashing Requirements), and has been providing the results to end users. The testing conducted at the Arkansas lab includes UHF RFID inlays operating somewhere in the range 800 to 1,000 MHz while the UHF RFID spectrum in Europe is centered on 865 MHz. The University of Parma's testing will be performed in a simulated real-world environment, such as reading tags through boxes of apparel passing through a portal, or on items placed on smart shelves, While The Arkansas RFID Research Center, on the other hand, carries out its testing both at retailer’s own stores to establish use cases and conduct audits, and inside an anechoic chamber to compare those real-world results with a chamber-based inlay performance benchmark.

The Parma laboratory will issue a certificate to any RFID technology provider that submits products that have completed the program, and will be provide a report indicating the testing results. Those results could then be used by the vendor to promote its products to end users.

The Parma RFID Lab has developed a strict set of protocols for approximately 10 use cases for which fixed and handheld readers, desktop interrogators, printers and tags will be tested. Use cases include tag encoding; scenarios to simulate the handling, packing and shipping of tagged products within a distribution center; and such store use cases as receiving, counting inventory and electronic article surveillance (EAS) operations. Tags and inlays will be tested for all use cases, while readers and printer-encoders will be tested in a subset of use cases relevant to the type of hardware being tested, such as fixed readers in the simulated logistics setting, and handhelds for inventory purposes within a store.

Every inlay, tag, reader or printer will be put through 50 replications, Rizzi says, to be tested in each use case, "in order to have enough data for statistical significance." Printer-encoders, he notes, will be tested for the accuracy and speed at which they print and encode tags. He declines to specify which makes and models of RFID hardware will be used to carry out the testing, explaining that to do so may be perceived as an endorsement regarding the performance of particular tags or readers.

The laboratory researchers and advisory board members, Rizzi says, have opted not to dictate thresholds regarding the hardware being tested—such as requiring a specific rate of accurate reads, or speed of reading—to achieve certification. "We'd rather leave it to the end user to decide if the results are good enough," he states.

Initially, the RFID Lab has contacted the approximately 30 RFID vendors with which it had previously partnered on other projects, and has invited them to submit their products for testing. However, Rizzi notes, any RFID firm is welcome to provide its hardware for testing. To have its hardware tested, a company will be asked to pay a fee to the lab, equivalent to the testing cost. The lab will then make the results available to end users at no cost.

To date, two RFID device manufacturers have already indicated their intention to submit hardware for testing: ADT Tyco and Motorola Solutions. ADT Tyco will submit a tag and a reader, while Motorola is submitting four reader models: the FX9500, FX7400, MC3190-Z and MC9090-Z.

At a workshop for RFID technology end users, scheduled to be held in spring 2012, the lab plans to present certificates to the hardware vendors whose products have been tested, and to also offer educational programs to end users, as well as to members of the lab's Board of Fashion Advisors.
