iButton vs RFID vs BLE: Choosing a Driver ID System

Knowing who is driving each vehicle is the foundation of any per-driver analysis: mileage, speeding, hours of use and accountability after an incident. There are three common technologies to get there: iButton, RFID and BLE (Bluetooth). None of them wins in every scenario; each one solves the problem with a different trade-off between convenience, ruggedness and cost.

🎯 Who this article is for: fleet managers, tracking companies and integrators who need to decide how to identify drivers before installing the devices.

If you have already chosen the contact key, our iButton and 1-Wire page has the full technical details.

What driver identification solves

A GPS tracker knows where the vehicle is and what it is doing, but not who is behind the wheel. When a vehicle runs several shifts or is shared by several people, without identification all the data ends up under the vehicle's name instead of the person who was driving.

Identifying the driver lets you:

• Assign every trip to a person: distance, schedules and events are tied to whoever was driving.
• Control who can use the vehicle: only authorized people open a valid session.
• Spot unexpected use: a vehicle moving with no identified driver is a red flag.
• Have evidence after an incident: date, time and driver linked to every event.

The device records who is at the wheel; per-driver reports and alerts are built in your tracking platform (Wialon, Traccar or whichever you use) from that data.

How each technology works

🔵 iButton: contact key (1-Wire)

An iButton is a stainless steel button with a unique code burned in at the factory. The driver touches it briefly to a reader mounted on the dashboard; the metal contact closes the 1-Wire bus circuit and the device reads the code. The key has no battery and its service life is measured in years. For the basics, read iButton driver identification: complete guide.

🟡 RFID: proximity card or key fob

RFID identification uses a card or key fob with a chip that is read by holding it close to the reader, without physical contact. It works like a building access card. The reader needs its own power supply, and the tracker has to be compatible with the way that reader outputs its data.

🟣 BLE: the driver carries a Bluetooth device

With BLE (Bluetooth Low Energy), the driver carries a device that broadcasts a signal, such as a wristband. The tracker detects it automatically while it is inside the vehicle: no gesture needed. In exchange, the identifier has a battery, and you need to account for signal range, since a device close to the vehicle can also be detected.

Comparison table: iButton vs RFID vs BLE

Criterion	iButton	RFID	BLE
Driver gesture	Touch the key	Hold the card close	None
Risk of forgetting to identify	⚠️ Medium	⚠️ Medium	✅ Low (if carrying the device)
Identifier durability	✅ Very high, stainless steel	⚠️ Cards bend or get lost	⚠️ Depends on the battery
Battery in the identifier	✅ No	✅ No (passive)	❌ Yes, needs replacing
Installation	2-wire reader, no power needed	Powered reader compatible with the tracker	No reader if the tracker has BLE
Relative identifier cost	Low	Low	Medium
Lending or impersonation	⚠️ The key can be lent	⚠️ The card can be lent	⚠️ The device can be lent
Dirt, vibration and moisture	✅ Very rugged; contact is easy to clean	✅ Contactless, reader must be protected	✅ No exposed contacts

None of the three prevents a driver from lending their identifier on its own. What changes is the effort: with iButton or RFID there is a conscious gesture; with BLE identification happens by itself, which cuts down on forgotten logins but also makes it less visible who opened the session.

What Rinho supports

Rinho makes the hardware; driver identification is handled in the device and the platform receives the data. Here is the support by model:

Method	Spider IoT	Smart IoT	Zero IoT
iButton (1-Wire)	✅ 1 port	✅ 2 ports (A and B)	❌
BLE with ID Band	✅	✅	❌
RF433	✅	❌	❌
Manual or from platform	✅	✅	✅
Native RFID reader	❌	❌	❌

⚠️ Important: Rinho devices do not have a native RFID card reader. If you need gesture-free identification, the alternative is BLE; if you want ruggedness and low cost, iButton.

iButton on Spider IoT and Smart IoT

The Spider IoT has one 1-Wire port and the Smart IoT has two, and the key can go on either of them. On top of that, the device offers:

• A list of up to 100 authorized drivers, stored in memory and kept after a restart.
• Driver sessions: each session records the code, the identification source, the start time, total duration, time with ignition off, time with ignition on and distance traveled.
• Signals for rules: active session, attempt with an unauthorized key, or identification of a specific driver on the list. With the event engine you can use them to, for example, trigger a buzzer or a relay depending on the key.
• Firmware 1.09.28: on the Spider, the iButton key and 1-Wire temperature sensors can now share the same cable.

The full details are on the iButton driver identification page, and the wiring step by step is in how to connect an iButton reader to a GPS tracker.

BLE with ID Band

The ID Band is an IP67 BLE wristband that the Spider IoT and Smart IoT detect without the driver doing anything. It feeds the same session system as the iButton. You can see how it fits with the rest of the accessories in BLE sensors.

RF433 and manual mode

The Spider IoT also accepts RF433 identification. On every device, including the Zero IoT, the driver can be assigned manually or from the platform.

💡 Tip: before deciding, check how your platform displays driver data. The device sends it, but not every protocol carries it the same way.

How to choose for your use case

If you need…	Choose…
Maximum ruggedness in dust, mud or vibration (agriculture, mining, construction)	iButton
No gesture at all from the driver	BLE with ID Band
The lowest cost per driver and a maintenance-free identifier	iButton
Control over which drivers can use each vehicle	iButton with an authorized list and rules
Keeping the RFID cards your company already uses	RFID, on a tracker with an RFID reader (Rinho devices do not have one)
Identifying drivers in a fleet running Zero IoT	Manual or platform assignment

In practice, the iButton remains the most balanced option for most work fleets, and BLE wins when driver convenience is the priority.

Frequently asked questions

What is an iButton and what is it used for?

It is a button-shaped stainless steel key with a unique factory code. It lets the tracker know which driver is using the vehicle: the driver touches it to the reader and the device opens a session under their name.

Can I block the engine if no valid driver is identified?

Yes, but it is not a one-button feature: it is built with event engine rules, a device output and a relay. That way you define what happens when an unauthorized key is used.

How many drivers can I authorize on one device?

Up to 100 codes per device. Each position on the list can be used in rules, so you can act differently depending on the person.

Does Rinho read RFID cards?

No. Rinho devices do not have a native RFID reader. For contactless identification, the option is BLE with the ID Band on the Spider IoT or Smart IoT.
