Vikings fans made the switch to digital tickets without any apparent glitches on Saturday.
The Vikings are one of six NFL teams to take only digital tickets via fans' smartphones this year, but the rest of the league is expected to switch to all-digital in 2019.
Saturday's preseason game against the Jacksonville Jaguars at U.S. Bank Stadium was the first time the new policy was enforced.
"I prefer them digital," said 16-year-old Joey Powers of Edina, who waited outside one of the security lines at the stadium with his grandparents. "I don't have to print it out."
If using the Vikings' mobile app, fans can also access real-time information about important details like road closures, gate backups and discounts.
"I don't have a problem with it myself," said Kent Lestrud of Princeton, Minn., who attended the game with his two sons. "Let's say I get separated from one of my sons. I can send it to them and they can still get in."
Lestrud, a season-ticket holder, said he started to take screenshot of his tickets on his cellphone last year. However, he said he could see how digital tickets may not be easy for everyone.
"If my parents were going to try to go to a game, they don't even have smartphones," he said.
