Every Tagged Vehicle or Carton, Read Automatically.
An RFID gate reader turns any doorway, dock or lane into an automatic checkpoint. Mounted with directional antennas, it reads every UHF-tagged vehicle, pallet or asset that passes — no hand scanning, no stopping — and logs the movement in real time. Identium manufactures UHF gate readers tuned for India’s 865–868 MHz band, WPC-approved and BIS certified.

Where gate readers are used
- Vehicle entry & parking. Paired with tamper-evident windshield tags, the reader opens a boom barrier in under a second — the backbone of RFID vehicle & parking management for societies, campuses and malls.
- Warehouse docks. A gate/portal at each shutter reads whole pallets on the move, automating goods-in and dispatch and killing manual carton scanning.
- Access control. Doorway readers log people and assets moving between zones for access and security.
- Asset movement. Track high-value assets as they leave or return to a controlled area.
What makes a good gate reader
- Long range and high output power for a reliable read across the full lane or doorway.
- Directional (circular-polarised) antennas so tags read regardless of orientation. See our RFID antennas.
- Multi-port support to cover both sides of a lane or several doors from one reader.
- Clean integration — relay outputs to trigger barriers/turnstiles, plus an SDK and demo source code for your software.
- India-tuned & certified — shipped configured for India’s 865–868 MHz band — several fixed-reader models also support the FCC 902–928 MHz band, so state the country of installation — with WPC-approved readers and antennas, and BIS certification.

How to specify an RFID gate reader
Frequency first. A gate reader catching vehicles, pallets, trolleys or files on the move is passive UHF — EPC Gen2, published as ISO/IEC 18000-63 and sold as RAIN RFID — because of the passive technologies only UHF reads several metres out, and a whole trolley at once. If the credential at your gate is a card or fob presented at a turnstile, that is HF at 13.56 MHz (ISO 14443 / ISO 15693) and wants an HF reader instead — see the RFID cards for access control guide. Specifying one and buying the other is an error we see often enough on gate tenders to raise it first.
Then pick the form factor — it follows the width you must cover:
| Walk-through portal (HLR200) | Fixed reader + external antennas (IHZ4) | |
|---|---|---|
| Read span | Up to about 4 m across the portal | Specified 0–30 m; a gate lane is normally trimmed far shorter |
| In/Out direction | Built-in two-way direction sensors | Derived in software from antenna port order and RSSI, or from a photo-eye or floor loop wired to the reader’s inputs |
| Antennas | Built into the two panels | Up to four external on SMA ports; gain and polarisation chosen per lane |
| Output to site | Integrated LED, industrial alarm and buzzer at the gate | 3 relay outputs and 3 inputs, plus Wiegand, RS-232/485, RJ45 and USB |
| Suits | Doorways, corridors, store and library exits | Wide vehicle lanes, dock shutters, multi-lane gates |
What decides the outcome is where the read zone stops, not how far it reaches. A gate run flat out will read the next lane, the rack behind the shutter and stock that never moved. Start low — output on a fixed reader is adjustable in 1 dBm steps — tighten the beam with antenna aim and tilt, then prove the zone with tags parked just outside it. India’s ceiling pushes the same way, because it is a radiated figure: 2 W e.r.p. counts the antenna’s gain, not the reader’s output alone, so a reader at its 33 dBm maximum behind a 9 or 12 dBi panel is well past it. The budget belongs to the installed combination, so confirm yours with WPC. Every figure here is typical and environment-dependent; steel shutters, wet floors and metallised windscreens all move them.
Check the band detail before a tender closes. India’s licence-exempt UHF allocation is 865–868 MHz under G.S.R. 853(E) of 10 December 2021, made in supersession of the 2005 rules that set 865–867 MHz. Its Table IV permits 2 W e.r.p. only in four channels of up to 200 kHz, centred at 865.7, 866.3, 866.9 and 867.5 MHz, and limits continuous transmission to 4 seconds on a channel with at least 100 ms before the next burst on it — which matters for a portal polling all day. Type approvals granted under the 2005 rules stay valid for their service life, which is why rival specifications still quote the old figure. Ask us to confirm the channel plan on the unit quoted, and verify the current position with WPC.
Send us this and we can quote against your actual gate: clear width of each door or lane; mounting height and surface; what passes through (tagged vehicle, pallet, trolley, files, people); the tag and the surface it sits on; whether In/Out direction is required or presence alone; what must be triggered and its input type; and the cable run to each antenna.
