Despite the fast-developing technologies and countless time management software solutions, the old-fashioned paper timesheets remain widely spread among drivers in many countries and businesses around the world, causing havoc and misunderstandings. To address this issue and create an opportunity for new market niches, Teltonika Telematics presents an automated time measuring using a GPS tracker and 1-Wire technology.


It is a common practice in most businesses around the world to keep employees accountable by recording, tracking, and analysing their working hours one way or another. It could be hard copy timesheets, time logs, workforce management software solutions, clocking in/out machines, etc.

When it comes to the corporate fleet drivers and workers or contractors operating vehicles in construction, forestry, agriculture, healthcare, retail, manufacturing and similar industries, hard copy timesheets still are being widely used today.

But this old-fashioned ‘pen and paper’ method has a few major drawbacks - members of staff may complete the daily procedure with a few days delay or forget to do so completely; writing errors, poorly readable hand-writing, inaccuracies or even dishonesty are quite common; paper sheets can be lost or given to a payroll department too late for the certain time accounting period. Overall, this old-school approach is pretty time-consuming, inconvenient, and error-prone.

To address this considerable challenge and assist corporate fleet management to run a business smoothly and efficiently, Teltonika Telematics introduces a practical present-day solution - an automated drivers’ working hours measuring system utilising GPS trackers mounted on vehicles and relevant accessories for this matter.



The method is based on the 1-Wire communication bus system combining a contactless Radio-frequency identification (RFID) card, 1-Wire RFID reader, and Teltonika GPS tracker model compatible with 1-Wire communication. Each and single one RFID card has a unique factory-programmed 64-bit identification number which is used for a driver’s authentication and the exact electronic date and time stamping.

Alternatively, a portable stainless steel iButton (aka Dallas Key) can be used instead of an RFID card, but the operating principle remains the same. As an example, for this use case, we choose RFID. Here to say, a 1-Wire RFID reader has to be mounted in a vehicle dashboard and connected to an FM device.

How it works - every mobile employee-driver is given an RFID card. When starting a shift, a person has to authenticate itself by bringing an RFID card nearer to a 1-Wire RFID reader. If authentication is successful, the ‘start of shift’ event electronic date and time stamp will be generated and registered, an ignition starter engaged. Vehicle driving is authorised, and an employee is welcome to start his/her duties.

Contrary, if the authentication fails, a car ignition starter will remain disconnected to prevent undesirable actions. When a shift has finished, and a driver is done for the day, the RFID card has to be touched to a 1-Wire RFID reader again to generate an ‘end of shift’ electronic stamp, and now vehicle ignition can be switched off for good. The same principle applies to lunch, tea or any other relevant breaks over working hours.


It is worth mentioning, depending on company needs and project specifics, the driver’s authentication can be enabled/disabled in tracker configuration settings section ‘Features’. Also, various ‘iButton Read Notification’ scenarios can be set by activating one of the output controls DOUT 1, DOUT 2 and its duration (see the image below). For instance, the DOUT signal may be utilised to notify a driver that authentication is successful, and access has been granted.

There is even more good news - an alternative time tracking method is available, quite straightforward and, of course, automated one using Teltonika tracker ‘Ignition ON Counter’ feature. This scenario counts the time spent with the switched-on ignition in the resolution of seconds (see the image below). Thus, by combining the feature with other vehicle tracking data (e.g. location, speed, geofencing), fleet managers and business owners can get pretty accurate working hours and activity reports to keep employees and drivers accounted. It is also known as a horometer or hour meter.


The key benefit of this scenario - its simplicity and low-cost installation. No extra accessories are required, no holes to drill in the dashboard of every single vehicle, no lost ID cards. The feature is available in Teltonika basic firmware, starting from the version 03.27.XX and above.

Thanks to GPS tracker extensive functionality, all required and relevant to a particular company data such as fleet vehicle locations, drivers’ working hours, driving times, mileage, speed, fuel consumption, and so on will be tracked, registered, and sent to the dedicated server automatically for further monitoring, analysis, wage calculation, and reporting purposes.

Even more, if the same vehicle is being shared among a few drivers, such a solution allows tracking each of them individually, computing the relevant data, and measuring their productivity (or any other key performance indicator) over the set period. As a result, all mobile workforce remains 100% accountable hassle-free way in real-time with no paperwork, human errors, disputes, or delays surely improving business efficiency and profitability.

Based on Teltonika FM device and its accessories comprehensive data gathering and dedicated 3rd party software, the method allows to calculate automatically and precisely of lunch break deductions, holidays, sickness absence, overtime, downtime, travel times to a project site, relevant expenses, allowances, evaluate employees discipline, etc. And, of course, authorised project and fleet managers can access this data via PC, tablet or smartphone which makes it even more practical and convenient.
