miniDaT-WEB-e-Basic – Optimise billing and service

All you need ...

... for cost-efficient machine data collection and anti-theft protection is provided by this data acquisition device!

You can monitor machine running times to optimise service provision and revenue. Knowing the whereabouts of equipment at all times helps your staff repair and move the machines. Simply switch off the machine at week-ends or in the evening. This will prevent use by non-employees and damage to the equipment.

Obserwando for Smartphones is also available to display the data collected and to switch off machines!

RFiD access control to prevent unauthorised use, loss of materials, machine damage

RFiD access control allows you to restrict access to work equipment and containers to instructed and authorised persons. This will prevent damage to machines and injury to persons and increase the availability of the work equipment.

With regard to material containers, you will drastically reduce loss of materials.

You can use Obserwando to release work equipment for the operators. You can also view who has used the machines where and how long.
