RFID Fuel Automation: Vehicle Tags at Petrol Pumps, India

How does RFID fuelling work at a petrol pump?

Oil-company fleet programmes describe it in their own words. One programme's fleet card page lists chip card, mobile and RFID as transaction modes at its petrol pumps, with two-factor authentication. The same programme's RFID page describes automatic vehicle identification by RFID, with the dispenser waiting for online authorisation before it starts, so the fleet owner knows how much fuel went into the vehicle's tank. Another oil company offers an NFC-based fuelling option at select pumps, where the customer can pre-set the fill from an app; NFC is a short-range relative of RFID.

In outline, the sequence is:

1. Enrolment: each vehicle in the fleet account gets a tag, linked to its registration number and fuel limits.
2. Arrival: a reader at the island reads the tag as the vehicle pulls up.
3. Check: the system confirms the account, the vehicle and any limits, and may ask for a second factor such as the driver's card or PIN.
4. Release: the dispenser is authorised for that vehicle.
5. Record: the quantity, time and place are logged against the vehicle and billed to the account.

The tags in those programmes are issued by the programmes themselves; the tags in this guide are for your own depot and do not work at a public pump.

Vehicle tag, driver card or FASTag: what is the difference?

A fuel programme's tag is a separate tag, not a FASTag, even though both are passive UHF tags on the windscreen. Our vehicle RFID tag guide explains how FASTag and gate tags relate.

How do you set up RFID fuel dispensing at a private depot?

A private depot needs four parts: a tag on every vehicle, a reader at the island, a controller with the vehicle list, and an interlock to the dispenser.

Tags are sold with a minimum order of 500 pcs, and readers from 1 unit.

The interlock. The reader passes the tag number to the depot's fuel-management controller over Wiegand, RS485 or Ethernet. The controller checks the vehicle against its list and limits and then releases the dispenser through the dispenser's own control interface or a relay input that the dispenser maker provides. The IF9C's relay can carry that release signal where the dispenser maker approves it, but the decision belongs in the controller, which also records the quantity dispensed. Nozzle readers, dispenser controllers and pump electronics are the dispenser maker's parts; we do not supply them. Our guide to RFID reader interfaces explains Wiegand, RS485 and the other options.

Siting the reader. Fuel dispensing areas have their own rules for electrical equipment, and none of the readers in this guide is listed as rated for hazardous areas. Mount the reader where your licensed installer and the dispenser maker approve, and set its power so it reads the vehicle at the island and not the one in the next lane.

Where should the tag go so it survives diesel, heat and washing?

• Windshield: inside the glass, as the product pages specify, away from the wipers' sweep and any metallised sun film, which can block UHF signals. A tamper-evident label breaks if someone peels it off to move it to another vehicle.
• Filler neck: where the windshield is far from the island, or where you want to confirm the tank rather than the cab, screw an on-metal tag beside the filler, outside the area where fuel splashes and drips.
• Tankers and heavy vehicles: a stud-mount tag on a bracket keeps the tag clear of the body's metal and away from pressure-washing jets; test the read before fixing a batch.

None of these tag pages states an IP rating, so fix a sample to one vehicle and run it through a few washes and refuelling days before tagging the fleet.

What about bowsers and mining machines?

Mines and large sites often take fuel to the machine with a bowser instead of bringing machines to a pump. The tag then goes on the machine's tank neck and the reader on the bowser's nozzle or fuelling terminal. Our diesel bowser and HEMM fuel automation guide covers that set-up, the tags that survive on a dumper, and what the recent coal-sector tenders ask for.

How do you check the tags in the yard?

A phone with the UCR10 UHF portable reader (₹12,000 + GST) plugged into its USB Type-C port reads tags up to 1.5 m away, which is enough to walk the yard and confirm that every vehicle's tag reads and matches the register. Do it after tagging, and again whenever a windscreen is replaced.

What should a depot fuel-automation specification include?

• Tag type per vehicle class (windshield, filler neck, stud-mount) and how tags are replaced when a windscreen is changed.
• UHF readers that work in India's 865–868 MHz band, with the interface your controller expects (Wiegand 26/34, RS485 or Ethernet) and a relay if needed.
• Whether a second factor (driver card or PIN) is needed, and how the two are matched.
• Who supplies the dispenser interface, and who approves the reader's position at the island.
• The records the controller keeps per transaction (vehicle, driver, quantity, time, dispenser) and how they reach your fleet or ERP software.
