Paperless tickets could help combat touts but many venues still do not have the capabilities to support them, say independent music promoters.
Although most tickets are sold online, bringing a printed barcode ticket means it is not truly a digital transaction.
But one independent promoter Anton Lockwood, who works for DHP, says paperless is not always "practical". "It only works where the cost of introducing the system can be spread over high ticket prices," he said.
"The physical design of arenas can make paperless tickets much easier to handle but in club venues, for example, it's more difficult as there isn't usually the space for equipment like electronic turnstiles."
Dave Newton of We Got Tickets, an online retailer, believes that the technology has actually made it easier for small venues.
"Paperless ticketing has brought the cost down [for smaller venues and promoters] and opened up the option of advanced ticketing," he said.
"Resistance is still there at the larger venues because they're used to having people stood on the door ripping tickets."
"Fans agreed that it is the future of ticketing."
New technology Other technologies, such as electronic wristbands and smartphone apps, may be the way that paperless ticketing is rolled out across the industry.
Technologies are also being developed for when people have actually arrived at the gig venue.
One of those includes inaudible frequencies, sounds that can be played out of speakers at gigs that cannot be heard by people but can be picked up by smartphones.
Theoretically the noise trigger could then make the smartphone bring up all kinds of content from merchandising or ticket purchase options or play video.
New innovations may also change the way people buy tickets in the future and how music fans experience the gig once they are actually there.
