The trolleys were first introduced across 10 stores in NSW in August last year as a part of trial.

Shoppers with an Everyday Rewards card can unlock a tablet-style device from a charging wall at the front of the store and attach it to their trolley to start shopping.

The device will allow shoppers to track their spending in real-time and pack their groceries as they go.

When shoppers are ready to check out with the trolleys, they will be able to head to the self-service checkout to pay for their shop.

The digital trolleys were first rolled out at 10 NSW stores including Kellyville, Kellyville Grove, Kellyville North, Lane Cove, North Parramatta, Oran Park, Schofields Town Centre, The Ponds, Warringah Mall and Windsor.

This month, the trolleys will launch at Woolworths supermarkets in Neutral Bay Village, Richmond, Menai, Mortdale, Revesby, Hornsby, Rutherford, Kotara, Green Hills and Erina.

In Victoria, the digital supermarket trolleys will be available this month at Chirnside Park, Malvern, Mornington East, Rye, St Helena and Thrift Park.

The Moonee Ponds store will receive the trolleys in September.

Eight Queensland stores will receive the trolleys this month, including Burleigh Heads, Caloundra, Capalaba Park, Currimundi, Nambour, Noosa, Northlakes and Warner.

Following the success of Scan&Go, Coles announced a trial of digital Smart Trolleys to “help shoppers save time, manage their budgets and checkout faster” in partnership with Instacart in November last year.

“Our customers have responded positively to the Smart Trolley shopping experience, praising its real-time spend tracking to manage their budget, the convenience of packing as they shop, and the ability to streamline the checkout process so they can pay on the trolley and go,” a spokesperson said.

The smart trolleys are currently being trialled at Coles Richmond Traders in Melbourne.
