Indiana Jeweler Uses RFID to Track Its Trinkets

By Claire Swedberg

Peter Franklin uses 13.56 MHz tags to take inventory of its stock, eliminating a process involving manual counting and bar-code scanning, and the associated human error.

Peter Franklin Jewelers, a Fort Wayne, Indiana, jewelry manufacturer, retailer and importer of diamonds and colored gemstones, is launching an RFID system in its three stores to decrease the labor required for inventory counts. The system, provided by RFID systems integrator Northern Apex, allows store managers to automate most of the inventory-taking process, sparing them and their employees hours of manual counting and bar-code scanning, as well as the human error that comes with that process.

For Peter Franklin, inventory-taking is a daily and time-consuming task. Ninety percent of items for sale are taken out of display cases each day and returned to safes for the night before being returned to the display cases the next morning. Not only does management need a regular count of all its items, it also needs to know whether each one is in its proper case.

The jeweler had intended to implement an RFID tracking system for several years, says Matt Foreman, sales and business development manager at Northern Apex, also based in Fort Wayne. Until recently, however, the company was unable to find an appropriate system offering a read range sufficient enough—and RFID tags small enough—to meet its needs.

Peter Franklin Jewelers' president, Peter Ball, says the RFID system they considered several years ago was still too early in the technology's development and, therefore, unsuitable. Until now, Peter Franklin has solely relied on hand counts and bar-code scans to track inventory. Every three months, the company performs a full hand count of every item in all three stores, Ball says, in addition to daily hand counts of specific cases. In the event of a discrepancy between the number of items counted and the expected amount, an employee scans the bar codes of each item to determine what item might be missing. This can also lead to errors, Ball says, if an employee misses a bar-code label.

The current system includes 1-centimeter-square Tagsys 13.56 MHz passive tags, made with chips sandwiched between the two adhesive sides of the jewelry's existing bar-code labels. According to Foreman, the tags use a proprietary Tagsys air-interface protocol and costs less than $1 apiece. Peter Franklin is deploying the system in phases, tagging its most expensive items first. Once all items throughout its Fort Wayne store have been tagged, it plans to deploy the technology at its two other stores, located in New Haven and Angola. Employees can read the RFID tags through the case by sweeping a handheld Tagsys reader over the case. If the case is deeper than the interrogator's 10-to-12-inch read range, workers must open the case and read the tags from inside.

Each tag's unique RFID number, captured by Northern Apex's Galaxy software, is sent through a USB Ethernet connection or a Wi-Fi interface to Peter Franklin's internal business application, FoxPro.

The new system should save the store many hours of labor, Foreman says. "If you think about the way people are taking inventory in jewelry stores today, it's the same way they did it in 1006—by hand," he says.

The system is being phased in this month as employees begin tagging jewelry items at the New Haven location. When a new item enters the store, an employee attaches an RFID tag, scans the item's bar code, and reads its RFID tag to associate the tag's ID number with that item. As the store eventually phases out its bar-coding system, Foreman explains, the store will simply input data about the item and then interrogate its RFID label. As each item is sold, an interrogator reads its RFID label once again, after which an employee removes it for reuse on another piece of jewelry. Each tag can be reused indefinitely, Foreman says, unless it is damaged. The company expects to deploy the RFID system fully at all three stores by the end of 2007.

While the system costs about $15,000, Ball says most of that price—about $10,000—was spent for the tags themselves. "There is a cost up front, but I think it will save us a lot of time and save in labor," he says. "We've always been very aggressive in our business, and we are being aggressive now in becoming as efficient as we can be."
