American Apparel Deploys Real-Time, Storewide RFID Inventory-Management Solution

The system, provided by Senitron, includes Impinj readers that capture the locations of all tagged items within a store in real time, eliminating the need to conduct inventory counts using handheld interrogators.

RFID startup Senitron has installed a fixed RFID solution at two American Apparel stores, enabling the retailer to view the real-time locations of all tagged items within predetermined zones throughout both sites. The technology, installed this spring at two Los Angeles shops, includes fixed Impinj readers and Senitron's antennas, as well as a software platform that manages data related to each read event. According to a press release from Impinj, the retailer intends to launch a chain-wide deployment of Senitron's system; American Apparel declined to comment for this story.

Senitron, a Los Angeles RFID solutions provider with a focus on retail environments, was initially launched in 2009 to sell an electronic article surveillance (EAS) solution employing radio frequency identification technology, says John Armstrong, Senitron's CTO. The company closed due to a lack of funding, but reopened this year thanks to new financial support, offering a new solution—a fixed RFID system designed to provide real-time location data throughout a store.

Most RFID solutions in use by retailers still provide inventory-tracking and out-of-stock data via fixed ultrahigh-frequency (UHF) reader portals installed at such locations as doorways between the stockroom and the storefront, or via handheld readers, operated periodically by store personnel to determine what merchandise is available on shelves. Senitron's solution is intended to supply RFID location data indicating not only which goods are in the store, but also in which particular zone within the backroom or storefront. And it does so using fixed readers, thereby eliminating the need for staff members to conduct inventory audits with handhelds.

In December 2012, American Apparel completed what has been an ongoing installation of an Xterprise UHF RFID system at all of its stores, consisting of fixed readers in the store room, as well as at the storefront entrance and at the point of sale. Employees also periodically utilize handheld readers to track which items are on the shelves.

Senitron approached American Apparel early this year with its more comprehensive solution, and the retailer agreed to test the technology initially at its 3,000-square-foot store in Little Tokyo, Los Angeles. Because American Apparel already tags nearly all of its merchandise, Armstrong explains, the installation proved to be fairly simple. However, the Little Tokyo store was selected as the first testing site due to the complexity of its physical design: Rather than being a simple box-like structure, the store is U-shaped, with a variety of nooks and alcoves within which tagged items may be located.

To ensure that all areas had full read coverage, Senitron installed approximately six Impinj Speedway Revolution readers and 70 antennas, and divided the store into zones. Based on which specific antennas captured a particular tag ID's transmission, the software can determine in which zone that tag is located. Each zone measures about 4 feet by 4 feet, or larger. If an item is removed from one zone and then placed in another—which may occur if a customer tries on a garment and then returns it to the wrong shelf—the system identifies that action. Staff members viewing the software can then quickly locate that misplaced item and return it to its proper location.

I know that American Apparel reached out to many different RFID solution providers, but what I really want to know is who are they for sure moving forward with? Is it this Senitron system, or is it Xterprise which is now owned by SML? Can anyone confirm anything for me? I'm just curious. Thanks!

Brady, this "in ceiling solution" did not move forward. nor did it ever integrate with our Clarity system for inventory execution in the store. be glad to discuss if you need to.

Brady, the senitron/impinj solution did not rollout nor was it ever integrated with the Clarity inventory execution from our company Xterprise. it was really focused on testing to see if planogram compliance could be achieved and that proved worthwhile but costly with 40 antennas in every store.

To understand more regarding the system i recommended following up with READBEE INC, the official Israel re seller of the Senitron system.
