I have successfully used Curve to pay for goods from Costco checkouts, but i am unable to use Curve at the automated petrol stations. When i first insert my card (before picking up the fuel nossel), the self service machine checks the card and then issues a card denied message, i cant get the the stage where i enter my PIN and take fuel. I’ve tried changing the underlying card to two different credit cards and my debit card, but i get the same error each time.
I assume the machine is trying to pre-authorise my card. Is there a way to use Curve at the petrol stations at Costco?
