The iButton device is ideal for any application where information needs to travel with a person or an object.

Today iButton devices are widely used in various application areas include:

Data Loggers
Asset Management
Electronic Asset Control
Guard Tour


The iButton device is the ultimate information carrier for automatic identification, secure authentication, and many portable applications.


Use iButtons for Driver Identification

Keep track of not only vehicles’ whereabouts but also who is Driving.

iButton is the technology used by most major fleet operators to identify the drivers in each vehicle of the fleet.

How does iButton works for Driver Identification

The operation of iButtons is simple yet very effective:

A distinctive key fob is assigned to each driver

A reader is installed in the vehicle which is connected to the GPS tracking device.

When the driver starts the vehicle he is required to present the key fob to the key reader. This associates him with that vehicle.

A LED light gives feed back to the driver that the key has been accepted


automatically logs and reports all driver activity

Powerful reports are then generated from this collected data. Reports can be run by vehicle or driver for any length of time containing times of log in and outs along with durations.

The reports will tell you, in detail:


Daily detail of the time when drivers start and finish to work

Total hours worked per day, week, month.

Since the iButton logs out the driver after each long stop (predefined by you), you'll learn more about the daily routine of each one of your drivers.

You can also generate summary reports with total hours worked.

Worked hours report per driver can be exported to excel for further analysis


IBUTTON is a solution for fleet management tracking:

1,    Driver authorization – gives ability to use vehicle only for specific iButton owners and identify which driver is on the road.  

2,    Immobilizer – without iButton authorization you can not run engine starter and and use vehicle.

3,    AutoGeofencing – gives ability to know when car leaves customized areas without iButton authorization.
