Tried self-checkout in Big-W

Last Sat, I went to Big-W for buying a fan. Well, I did a new things. I tried self-checkout. If you choose to pay by ETPOS(Australian version EPS), then you will be able to hanle by yourself. Scan the bar code and then pay, that is. But I paid by Credit Card, so a staff need to check the signature with the my card. Generally, it can save my time to line up, there was just myself in the self-checkout, no one use that.
