The new agreements are with Strathclyde Partnership for Transport, the regional transport body for the west of Scotland, and Greater Manchester-based Willow Park Housing Trust and Adactus Housing Group.

The three deals involve a total of more than 220 fleet vans and maintenance vehicles being fitted with the technology, which feeds back live information, recording speed, journey time, distance and precise location. 

Employers can also monitor the information in real time via their computer screen and it can be accessed anytime and anywhere in the world.

Raj Singh, managing director of Crystal Ball, based in Manchester, said: 'Securing these deals with such significant clients is a testament to the quality and robustness of the range of products and services we offer.

'The system will allow these organisations to monitor their maintenance vehicle fleets more efficiently and effectively.'

The Strathclyde deal also involves the fitting of Crystal Ball's Driver ID system, which provides coded Dallas Keys for more than 100 employees and a dashboard reader so companies know who is driving a vehicle at all times and can monitor driver activity across multiple vehicles.

Singh added: 'Driver ID provides a simple yet highly effective means of collating accurate data, thereby dispensing with manual and easily altered records.'
