New Brazilian Fashion Chain Launches With RFID

At its debut store, Memove is using its garments' sewn-in EPC Gen 2 tags to increase efficiency at its DC and store, as well as improve its customers' experiences.

At the store, the system includes six Speedway Revolution readers, used for POS and inventory checks, as well as three Speedway xPortal interrogators installed at doorways at the front and rear of the building. An xPortal first reads tags as goods arrive, providing an instant update to the list of store inventory in its Linx Sistemas software. The store also employs an RFID-enabled trolley, designed and provided by RFsense, which can be rolled past aisles in the back room or on the sales floor, in order to update the inventory—which takes only a matter of minutes to complete, the firm reports.

A customer wishing to make a purchase can go to a POS area and place all items in an RFID-enabled basket. The basket's built-in Speedway xPortal reader and Impinj Brickyard antenna capture the unique ID number of each garment's sewn-in RFID label, then forward that information to the store's POS software. The software calculates the sale amount and displays that data on a POS terminal adjacent to the basket, after which the customer can complete a sales transaction by swiping a credit or debit card at the POS terminal. At the same time, the inventory is updated to indicate which items have been sold. In addition, the basket's interrogator erases the label's encoded ID number, so that it can no longer be read. As the shopper carries his or her purchase out of the store, the fixed reader portal at the exit does not read the tags, and thus no alarm is sounded. However, if the tags have not been erased—thereby indicating that one or more items have not been purchased—an audible alarm is sounded.


Memove's store has a trolley, fitted with an Impinj Speedway reader, that the staff can roll through the back room or onto the sales floor, to quickly update inventory counts.

If an individual decides to return a previously purchased item, the bar code printed on the product's hangtag can be scanned, since the RFID tag is no longer operable, and the tag can then be re-encoded with its ID number. If the tag can not be reprogrammed, that failure indicates that the tag has been damaged by being laundered. In such a scenario, the store would refuse to accept the return, since it would know that the garment had apparently already been worn.

An Impinj reader installed in the store's floor, at the entrance of the changing rooms, also reads the RFID labels. When the device captures a label's ID number, it transmits that data to the Linx Sistemas software, which determines the number of items being carried over the reader, and displays that information on a screen mounted at the same location. In that way, the software can track how many items enter the changing rooms, and customers can view, in real time, the number of garments that they bring in to try on.

Memove intends to use the system for six months at its first store, before evaluating the results to determine whether the technology provided shoppers with greater inventory accuracy, security and convenience. Valdac will then decide how broadly to implement the technology among its other stores, including those already in operation, as well as any new locations that will be opening. Memove plans to open 54 stores within the next five years, Impinj reports, all utilizing RFID technology in one form or another. In the future, the Memove stores may also utilize the RFID labels to provide fitting-room readers that could interrogate the labels of clothing tried on by a customer, and display details regarding accessories or other garments that would complement those items. What's more, the fitting-room system will come with a push-button that will enable shoppers to request help from a sales associate.
