Everything seems to have gone digital, even trading stamps at the World Cup.

What was once a children's hobby of collecting, trading and pasting actual stamps in a book can now be done electronically in a computer,only this is free, without the glue, and it's brought to you by the same company best known for the pastime.

Coca-Cola's World Cup Web site, www.coca-cola.com/football, features a virtual Panini sticker album, where registrants can earn stamps with players' pictures, stats and biographical detail, trade them, and watch their collection grow.

"We have a good mixture of youth experiencing (Panini sticker albums) for the first or second time," said Coke's global marketing spokesman Philipp Bodentza. "But there's definitely revival players, as well. I'm 38, and I remember my Panini collection. It's fun to go watch and see all pictures from the previous tournaments, as well."

The album is a collaboration of Coke, an official World Cup sponsor; Panini, the Modena, Italy-headquartered company that has been producing soccer sticker albums since 1961 and World Cup versions since 1970; and White Plains, N.Y.-based Tokenzone, Inc., which developed the software to allow fans to collect and trade the stamps in 11 languages.

"One of the nice things, with 11 different languages, is it interfaces with the different languages, so you can trade with someone, say, in Japan," Tokenzone president Isaac Arias said.

After registering, visitors to the site earn stamps by various methods. They get three stamps every four hours, provided they log in again; get stamps for playin "The two are complementary," Allegra said. "The digital one will lead to the physical one. The environment creates buyers."
