About the Identium UHF RFID PCB Tag D16-25

Move up to a 16 mm disc and the read behaviour changes character. The Identium RFID PCB Tag D16-25 sets an M4QT chip in a D16x2.5 mm body and is rated up to 120 cm on metal, enough to sweep a rack bay or a stack of returnable crates on a walking pass with a handheld. This is the size Indian asset teams reach for when a smaller disc reads too short for the aisle but a large industrial housing will not fit the item. Mounted straight onto steel or aluminium, it gives a metal asset an EPC identity that lasts as long as the asset does.

Key specifications

Best-fit applications

• Returnable metal crates and stillages moving between plant and vendor
• Scaffolding tubes, props and couplers in a construction rental yard
• Server, network and UPS hardware in an IT fixed-asset audit
• Forklift attachments, cages and trolleys inside a warehouse
• Industrial gas cylinders tracked through fill, dispatch and return
• Electrical panels and distribution boards on a maintenance round

Mounting, encoding and reading notes

Bond this disc flat and hard against the metal surface, because a gap or a tilted bond costs range. There is no aperture here, so use structural epoxy or a heavy-duty double-sided adhesive on a degreased surface; for assets that get washed down or knocked about, a milled recess is worth the extra machining. Commission the tags on a desktop reader in stores, then confirm the 120 cm figure with your own handheld, at the angle and height your operators actually scan from, before you tag the whole fleet.

Why buy from Identium

Identium designs and manufactures its own RFID hardware and has done so since 2010. The D16-25 is made in India and tuned for 865-868 MHz, which matches ETSI 865-868 MHz, so export customers can draw on the same stock. Talk to us about volume and OEM requirements, encoding to your numbering scheme, or a sample pack. Browse RFID PCB and ceramic tags or plan the rollout with our RFID fixed asset audit guide.

Frequently asked questions

What is the read range of the Identium UHF RFID PCB tag D16-25?

The Identium IDTS-D16-25 UHF RFID PCB tag has a read range of up to 120 cm when mounted on metal. Real read distance in an Indian deployment depends on reader output power, antenna gain and the surface the tag is fixed to. It uses the EPC Class 1 Gen2 / ISO 18000-6C protocol.

Does this RFID PCB tag work on metal surfaces?

Yes, the D16-25 is an on-metal UHF RFID PCB tag meant to be fixed directly onto metal assets. Ordinary paper and label tags do not read reliably on metal, which is why anti-metal PCB tags like this 16 mm disc are used for tool and equipment tracking.

Is this UHF RFID tag approved for use in India?

Yes. The D16-25 PCB tag covers 860 to 960 MHz, which includes India's UHF RFID band of 865 to 868 MHz notified by WPC and usable licence-free within the permitted power limits. It is supplied by India RFID Store, a BIS and WPC certified Indian manufacturer, with pan-India shipping.

What is the price of a UHF RFID PCB tag in India and is bulk pricing available?

Pricing for the Identium D16-25 UHF RFID PCB tag depends on order quantity, so check the price listed on this page or request a bulk quote. India RFID Store is an Indian manufacturer offering bulk and OEM pricing, custom encoding and samples for evaluation before a large order.
