Fans in Austria and Switzerland are being given the opportunity to win tickets for the semi-final by registering with a member of the promotional team wearing Adwalker digital advertising units.
The Adwalker digital mobile unit is worn by its operators as a compact body pack incorporating an LCD screen, wearable computer, touch screen and printer, allowing for brand advertising, data capture, coupon printing and a gaming platform.
Castrol is promoting its www.castrolindex.com website where fans can analyse performances and effectiveness of some of Europe's best talent. It is the first time a digital mobile media platform such as this has been used at a major football tournament.
Simon Crisp, Adwalker chief executive, said the digital capability of its units carry the "power and sophistication to bring the message to the customer".
