Jim Faulds said the Dundee-based company was in talks with prospective and existing customers at home and overseas, after winning some big contracts in recent months.

The directors believe i-design's technology, which allows organisations to run adverts on cash machines, is a compelling proposition for firms like banks, which are trying to boost returns. They have been encouraged by signs that the technology has been winning a growing following. The company said revenues rose by 13%, to £1.6 million in the six months to March 31, from £1.4m in the same period last year.
