The group behind Ireland's first smart supermarket say the concept will be much more common here in the next few years.

The country's first 'frictionless' grocery shop opened its doors in Dublin on Tuesday.

It allows customers to pick up items and buy them electronically without the need to pay at the register.

'Market x Flutter' uses more than 90 cameras and artificial technology to let shoppers grab and go without waiting in line.

Stephen O'Sullivan is the group head of European workspace with Flutter.

He told Joe Lynam on Newstalk Breakfast it is a simple process.

"The customer downloads an app, they link their bank card to it - they come up to the gates of the store, they scan the QR code, they enter.

"They walk around the shop, they select the products that they want and then they walk right out."

The technology will also recognise if a customer puts a product back on the shelves.

They will then receive a receipt on their phone within "a couple of minutes" after they leave the shop.

He says the technology tracks the product, not the customer.

"There's no resources in the shop, there's just cameras in the ceiling that really much track the product as opposed to the customer itself in the shop.

"There's no facial recognition and no biometrics used in the store itself.

"It sees the individual in the shop as an avatar - a stick figure - but really focuses on the product that they've purchased and then watches it as it moves around the store".

And he says the concept will be used more widely in the next few years.

" I think it's going to take time for the technology to follow suit across larger retail operators.

"But I can definitely see this a lot more common in the next five years across the country."
