Woolworths apologises after self-serve checkouts crash

Woolworths says majority of its self-serve checkouts are working again after a chaotic afternoon caused by a nation-wide outage.

"Following IT issues this afternoon, the majority of our self-serve checkouts have now returned to normal operation nationwide, with the rest expected to follow later this evening," the supermarket said.

"We would like to thank our customers for their patience as we worked to fix the issue and we apologise for the inconvenience.

"Our stores have remained open and we've continued to process transactions through the checkouts operated by our team members."
