Identium provides RFID-based weapon management for armouries and security forces — tagging each weapon for instant identification, automated issue/return records and periodic stock verification.

Where the Tag Goes on a Weapon, and Why the Frequency Matters
An armoury system lives or dies on two decisions: where the tag sits on the weapon, and how tightly you control the read zone.
Passive UHF is the right frequency for the weapons themselves. It is the only passive option that reads a full rack in one sweep, at a distance of a few metres, without handling each item — HF at 13.56 MHz and LF at 125/134 kHz are close-range technologies and would mean picking up every rifle to scan it. Tags for this work are EPC Gen2 (ISO/IEC 18000-63), the passive-UHF air-interface standard marketed as RAIN RFID. As of 2026, 865–867 MHz is the delicensed UHF band for India under WPC rules, and Identium’s UHF readers and antennas are WPC-approved for it; check the current BIS and WPC position before you finalise a hardware specification. The personnel side is the deliberate exception: the credential presented at the issue counter is typically an HF 13.56 MHz card (ISO 14443 or 15693, Mifare or DESFire) or a biometric — neither is EPC Gen2 or RAIN RFID, which are passive-UHF terms only — because identifying the person drawing the weapon should be a single, intentional act rather than an ambient read.
Placement is a mechanical problem before it is an RF one. A steel receiver, barrel or slide detunes an ordinary label, so those surfaces need an on-metal tag, which carries a ground plane behind the antenna. Polymer stocks, handguards and furniture behave closer to free air and take a smaller standard hard tag. Either way the tag has to clear the action and the sight line, tolerate solvent and the heat that travels back from the barrel, and stay put under recoil. On the weapon itself that means bonding — epoxy or a structural adhesive — or a tag seated in a recess the armourer already has; drilling or riveting into a receiver, barrel or slide is a modification to the firearm and is not on the table. Rivets and cable ties belong on the crates, racks and ancillary kit around it.
| Item | Surface | Suitable tag | Attachment |
|---|---|---|---|
| Receiver, barrel, pistol slide | Steel | Compact on-metal UHF hard tag (ceramic, PPS or ABS) | Epoxy or structural adhesive |
| Stock, handguard, grip | Polymer | Small rugged UHF hard tag | Adhesive, epoxy-backed |
| Magazines, small accessories | Steel or polymer | Small on-metal tag | Adhesive, or seated in an existing recess |
| Ammunition boxes, transit crates | Steel or wood | Rugged sealed UHF tag | Rivet or cable-tie |
| Slings, pouches, body armour | Fabric | TPU or silicone tag, or cable-tie tag | Cable-tie |
| Rack or locker position | Steel | On-metal tag used as a location marker | Adhesive or epoxy |
| Personnel credential | — | HF 13.56 MHz card or biometric (not EPC Gen2) | Carried |
Small on-metal tags read shorter than large asset tags, and a densely packed steel rack shortens things again. Treat any range figure as typical for a given tag, antenna and environment rather than a guaranteed number, and confirm it on your own racks before the layout is fixed.
The common failure in a small kote is over-reading. Steel racks reflect signal, so a door reader ends up seeing weapons still in storage and the issue log fills with movements that never happened — which erodes trust in the record far faster than a missed read does. It is corrected with antenna aim and polarisation, reduced output power, session and inventory settings, and where necessary a shielded portal instead of a room-wide read. All of that is worth settling while the readers are being commissioned, not after go-live, and the read stream should be reconciled against the issue record from day one so a discrepancy is visible immediately.
