Amazon is introducing its latest palm-recognition technology to a concert venue in the US – meaning attendees will be able to use their hand as a ticket.

The retailer will be bringing Amazon One to the Red Rocks amphitheatre in Denver, Colorado, before it will be available at other venues in the coming months.

It is the first time it will be used outside of Amazon‘s stores, where shoppers can pay for food and other items by swiping their palms.

Concertgoers can sign up to connect their palm to a ticketing account by hovering their hand over a device ahead of the event – and will only need to sign up once.

They can then use their palm as a ticket to get into other venues at shows and events at the venue, and revellers don’t need an Amazon account to use it.

In order to bring the technology to Red Rocks, Amazon signed a deal with entertainment company AEG – which sells tickets on AEG’s ticketing site, AXS.

AXS chief executive Bryan Perez said other venues plan to add the technology in the near future, however, he declined to say where or how many.

Mr Perez said that concertgoers can reach their seats faster by using the palm technology rather than holding up their phone to an attendant to scan a bar code.

People who want to scan their palms will have a separate lane to enter the venue.

“You don’t have to fumble around with your phone,” said Mr Perez. “Your hand is always attached to your body.”

The technology has been met with some criticism, with privacy experts warning against companies using biometric data, such as face or palm scans, due to the risk of it being hacked and stolen.

But Amazon has said it stores the palm images in a secure part of its cloud and not on the Amazon One device.

It added that users can also ask for their information to be deleted at any time.
