RFID for Apparel & Fashion Retail

Two separate lines, and they behave differently. The recurring one is the per-piece passive UHF tag (EPC Gen2, ISO/IEC 18000-63), whose cost moves with the inlay and chip, the tag body — paper hang tag, coated card, or a washable sewn-in label — plus printing, serial numbering, encoding and annual volume. The one-off line is hardware and integration: handhelds per store, fitting-room readers and antennas, a portal per exit door, a multi-port reader and circular-polarised antennas at goods-in, cabling, and the work to connect your POS or ERP. Across a full year the tag line is usually the larger of the two for a chain tagging every piece, because it recurs while the hardware does not. Identium quotes against a written specification — garment mix, annual piece volume, store count, doors per store — not a per-store list price.

At source wherever your supply chain allows it. Source tagging means the vendor or your own unit applies and encodes the tag alongside the price ticket or care label, so goods arrive already countable and receiving becomes a carton read rather than a piece-by-piece tagging job. It also keeps one numbering scheme: you specify the encoding and the serial range, and every vendor works to it. In-store or DC tagging is the fallback — it needs a desktop RFID label printer, an encoding step and staff time on every piece, and retro-tagging stock already on the floor is a separate one-off project to scope. In-store tagging is often the practical way to run a single-store pilot before the tag specification is frozen. If you also ship to retailers who require source tagging, their own written specification governs the tag, not ours.

Usually, but placement decides it and every construction has to be proven. Passive UHF at 865–868 MHz is detuned by metal and absorbed by water, so zari and metallic thread, sequins, foil-blocked hang tags, buckles and eyelets on leather goods, and the metallic inks on some shoe boxes all shorten the working range when the inlay sits directly against them. Range there is typical and environment-dependent, not a fixed figure. The fixes are physical rather than electronic: move the inlay to the clear printed face of a swing ticket away from the embroidery, tag the outer face of a shoe box rather than an inner wall, and keep a few millimetres of standoff from any buckle or eyelet. Ask for a placement test on the actual article, tagged the way you intend to sell it, before the specification is frozen — a placement that reads on plain cotton can fail on the same style in zari.

It is the equipment that matters more than the premises. India's licence-exempt RFID band is 865–868 MHz under the 2021 WPC short-range-device rules, subject to the power and channel conditions in that notification, so a passive UHF store installation does not normally involve a per-site radio licence. What does need checking is the reader: it has to be approved for that band and actually configured to it. Units bought on an overseas default often arrive set to the 902–928 MHz FCC plan, which is not India's allocation at all — and even within 865–868 MHz the reader has to be set to the channels India permits. Identium is BIS certified, and the UHF readers and antennas we supply for India are WPC-approved for India's licence-exempt UHF RFID band. Confirm the current position with WPC and BIS before you freeze a tender specification or place an import order.

Through your own software, with your ERP still the stock ledger — RFID contributes a count, not a second system of record. Every reader we supply ships with an SDK, a demonstration application and source code, so your team or your integrator reads tag events directly rather than waiting on a closed platform. Most of the effort is mapping and reconciliation: each tag carries a serial unique to one garment, so you need a rule that resolves a tag's EPC to your style-colour-size SKU, and a step that posts a counted-versus-expected variance instead of overwriting stock on hand. Decide early whether fitting-room and exit-gate reads feed the same system as cycle counts or a separate loss-prevention view. Name your POS or ERP in the written specification when you ask for a quote, so the integration points are agreed up front rather than discovered during the pilot.
