John Berry was once described by his daughter's teacher as 'the man who draws all those lines on products'. Happily that is not true. But he has been involved in the world of bar coding for almost 20 years, including periods as Chairman of the GS1 UK organisation and Chairman of the GS1 global organisation. He worked for Boots in the UK for over 25 years and was responsible for introducing point-of-sale scanning to over a thousand stores. He has also held non-executive positions on the boards of several companies in the retail industry.
