This year's Longitude music festival will only be accepting digital tickets.
It's taking place on the first weekend of July, with acts such as Tyler the Creator, ASAP Rocky and Dave performing headline slots.
200,000 concert goers are expected to visit Marlay park that week, with Green Day, Guns 'n' Roses and the Red Hot Chili Peppers playing individual gigs in the days before the festival.
Garda Superintendent Ian Lackey is asking attendees to keep their phones charged.
"In previous years, we have had issues, particularly with young people, who have come up from dopwn the country with their printed off ticket, to find out it is already a duplicate and somebody else has already gotten in.
"We ask people who are attending the event to have it downloaded and available to them because the last thing we want to do, and we would have to do, is to disappoint people and turn them away on the day."
Meanwhile, concert goers attending Marlay Park in Dublin in the coming weeks are being advised to leave their cars at home.
From June 27th to July 3rd, the venue will host a number of concerts with thousands of people flocking to Rathfarnham.
Garda Superintendent Ian Lackey wants to reduce the effects the gigs will have on nearby residents.
"It does inconvenience the local community, we are very aware of that
"We try to minimise that as much as we can
"For that reason, we would ask that anyone who is coming to any of the 6 days of the concerts that they would use either the LUAS, public transport or bus providers from all around the country that will be coming here.
"It makes everything so much easier."
