Illegal Euro ticket sales draw fines
European football's governing body, Uefa, has already fined hundreds of people for illegally reselling their tickets for the Euro 2008 championships in June.
As part of the original purchase conditions, holders are not allowed to pass on their tickets to other people for the matches being held in Switzerland and Austria.
Euro 2008 spokeswoman Pascale Vögeli told Swiss public radio on Saturday that Uefa has been carrying out regular checks on the internet to crack down on illegal sales.
If there is proof of banned trading, the association can cancel the tickets and fine resellers.
Vögeli warned that most tickets that are being sold online are fakes and were already up for grabs before official sales began.
