In order to figure out why your physical card isn't working we need to figure out the following:
Was your card activated? If not, you can activate it in app or by completing a card payment or ATM transaction with chip and PIN
Is your card blocked? If so, please unblock it in app
Is your card terminated? If that's the case, then the only option is to order a replacement
Are your contactless payments failing? You can only pay with contactless after you have completed a payment with chip and PIN. You may have reached your contactless payments limit. If that's the case, please reset the limit in app and you'll be good to go
Your card is physically damaged, broken, bent, etc? In that case the right thing to do is to terminate it in app and to order a replacement
Your card seems to be physically fine, unblocked, it worked perfectly but now it just doesn't work anymore? Please reach out to the Support Team, perhaps there's something else we can do to sort the issue. If not, we will help you order a replacement.
