London 2012 has unveiled the design of the Olympic and Paralympic Games tickets with their delivery, along with Games travel cards and spectator guides, set to begin this week.
The tickets have been designed by FutureBrand, part of McCann Worldgroup, and each features the sport pictogram and colour scheme of a specific venue to help spectators find the correct destination.
Each ticket will be printed with a hologram, a barcode and the name of the booker as well as several other security features to reduce the possibility of counterfeiting.
This will ensure every ticket can be traced to the person who purchased it.
London 2012 also has a URL checker on the website which will confirm whether any rival site claiming to sell London 2012 tickets is genuine or not.
"With the Olympic Flame now making its journey towards the Olympic Stadium, and with 100 days to go before the Paralympics, I can't remember a more exciting week on the road to London 2012," said London 2012 chief executive Paul Deighton.
"It is important now that people keep their tickets in a safe place ready for Games time and to be wary of websites and organisations claiming to have Games tickets to sell.
"In many cases, they simply do not have them to sell and there is a real danger people will end up being out of pocket and missing out on seeing the Games."
He warned purchasers: "If in doubt, check our website and be 100 per cent certain you are buying from an authorised source."
