3M Launches Asset and Inventory Tracking System

By Claire Swedberg

The solution includes 13.56 MHz passive RFID tags, handheld and pad readers, and a hosted software application in which asset data can be stored online.

Later this month, 3M plans to release its Asset and Inventory Tracking System, with a hosted software application that will allow organizations such as IT departments and construction equipment managers to use RFID or bar-coding to track their assets. To test the system's flexibility, the company is preparing to pilot the technology to track laboratory equipment within its own facilities in St. Paul, Minn.

The solution includes high-frequency (HF) 13.56 MHz RFID hardware, compliant with the ISO 15693 standard, and is designed for midsize or smaller businesses seeking to track assets without installing software that must be integrated and maintained, or wiring hardware such as fixed reader portals. The software application in which data regarding those assets is stored and displayed is hosted by 3M, and can be accessed via the Internet.

The system is easy to install and use, and requires limited investment, says Tom Mercer, the marketing manager of 3M's Track and Trace Solutions division, because users would need only upload existing data about the assets into the server software, place a passive RFID tag (or a bar-coded label) on an asset, and then utilize a Socket Mobile 650 handheld interrogator to read the unique ID number encoded to that tag. 3M also offers a reader pad so that tags can be interrogated by placing the tagged items on the pad—as they are being checked out of storage or returned, for example, or as they enter a new building.

In this way, companies can track the time and date an item was moved. When performing audits, workers can use the handheld reader with a Wi-Fi connection that lets it communicate with the hosted 3M software. They can also utilize the reader's keypad to input a specific item they are seeking, and the handheld would alert the user when that unique ID number was detected. Alternatively, the interrogator can also be used to take inventory, with a user walking throughout a facility to count all items—such as phones, PDAs or laptops—within read range (up to 12 inches) between the handheld reader and the assets' tags. Users can also select a "search and report" function in the server to run reports on inventory, or on the location or use of the assets.

One way 3M could prove the system's use, however, was to test it within its own company. Because the firm already has a large inventory-tracking system in place for its IT assets, 3M selected a smaller use case that would be more typical of those of its customers. In this case, the company chose to track laboratory equipment. Beginning in early April, 3M intends to employ the system to manage 400 pieces of equipment that require regular audits and must be tracked from one building to another. The equipment consists of balances, oscilloscopes and other calibrated devices used in the design and development of 3M products.

In the past, that tracking had been conducted manually, using pen and paper. Each time an audit occurred, a list would be created and printed. One or more people would walk through the labs searching for assets, and then cross them off the list. "The manual process of crossing off lists, compiling the information, took quite a bit of time," Mercer explains. "Now, with the handheld, they can walk around and scan each item quickly. If there is a bar code on the item, they will scan the bar code; if there is an RFID tag on the item, they will scan the RFID tag."

The labs are located in several buildings on the St. Paul campus. The users intend to scan some items' bar codes, while attaching RFID tags to the type of objects that move the most—namely, the balances. Each lab location will have its own reader pad. When a worker brings a new item into a lab, he or she will scan that object's bar code—or, if it's a balance, use a reader pad to interrogate its RFID tag. The software then will update that item's status as being in its new location, Mercer says.

When balances are due for their annual calibration, the staff expects to use the system to locate each balance based on the lab in which it was most recently scanned. "By tracking the location of the balances using RFID and reader pads," Mercer says, "they will have a better idea of where to look, and spend less time e-mailing around searching for a particular item." The pilot is expected to transition into a permanent deployment.

The company already sells a similar HF RFID system for tracking legal files and similar documents (see RFID Brings Order to the Law and Fort Hood to RFID-Tag Medical Records), and the new asset-tracking system is built on that technology. Although the asset-tracking solution uses the same HF tags that are utilized for file tracking, Mercer says, users could request Gen 2 UHF tags if they wanted a longer read range.

Most companies are currently still tracking their goods using Excel spreadsheets, or pencil and paper, Mercer says. "Surprise audits can take three days," he indicates. "Having a tool to automate that can be a real time-saver." Businesses could also employ the system to track the usage, maintenance and inspection of safety equipment, such as harnesses.

3M plans to sell the software, tags, handheld interrogators and reader pads through its Asset and Inventory Tracking System Web site, as well as through resellers. The reader costs $499, the handheld is priced at $1,399 and 1,000 tags are available for $400. A year's access to the hosted software application costs between $499 for one user and tracking up to 200 tagged assets, and $2,999 for 25 users and tracking up to 3,000 tagged assets. After 12 months have passed, the client would then have to renew its membership. The system can also scale larger, for a higher price, if the company requests it.
