RFID, or radio frequency identification, is a technology that uses radio waves to read data from small tags attached to items. Unlike a barcode, it needs no line of sight and can read many tags at once, which makes counting and tracking stock far faster.
An RFID system has three parts: tags, readers and software. Each tag holds a unique code, and often an antenna and a chip. A reader sends out a radio signal, tags in range respond with their codes, and the software matches those codes to product records. Because each tag can be unique, RFID can identify individual items, not just product types.
Apparel and footwear retailers are among the most common users, since items are high value, varied and easy to tag. Typical uses include rapid stocktakes, locating items in the backroom or on the floor, checking incoming deliveries and improving online stock accuracy for click and collect. Handheld readers, fixed readers at doorways and smart fixtures all feed the same data.
Pitfalls include metal and liquids, which interfere with radio signals, tagging processes that slow down receiving, and expecting results without good data discipline. Tag cost, reader placement and staff training all affect the return, so many retailers pilot a single category or store first. Standards such as UHF, which most retail systems use, help tags and readers work together.
RFID matters because accurate item-level stock supports fewer stock-outs, faster counts and better customer availability. RetailCare supplies and supports RFID solutions for Australian retailers.
