Self-checkouts in supermarkets have been in use since the mid-1980s, but the recent expansion of automated tools is provoking resistance from shoppers.

Hello, I'm Russell Padmore in Ireland, and in Business Daily, I'm checking out checkouts.

Here and around the world. Retailers like the technology because they can employ fewer staff.

Customers are certainly embracing automated checkouts. You can just see it from the queue in any

grocery store. But supermarket operators are facing a backlash from customers who expect service

with a personal touch. Between a quarter to a third of shoppers report that they hate self-checkout lanes.

We'll also hear how theft is a major problem at automated checkouts.

Somewhere between 15 to 20% increase in shoplifting.

So the loss prevention is getting quite expensive.

Consumers complain about disruptions when the technology fails,

but is the advance of artificial intelligence built into automated checkouts

the inevitable future for grocery shopping?

I'm walking across a supermarket car park in Srebane in Northern Ireland.

This store is just a minute's drive from the border with the Irish Republic

and it's popular with cross-border shoppers from nearby County Donegal.

As I push my trolley, I'm passing several cars with Irish registration plates.

The supermarket accepts the euro currency alongside the British pound and even has a

dedicated Euro self-checkout till. Shoppers around the world are increasingly avoiding automated

checkouts, unhappy about retailers replacing staff with robotic machines, as well as the

annoyance of delays when the technology goes wrong.

But I wonder what other shoppers here think of using self-checkout tools.

They're very convenient, but you know you don't want people losing their jobs to automated machines.
