The card details saved are location specific. If the guest places an online order for a particular location and makes payment through credit card, then the details of the credit card will be saved for that particular location. If the guest again places an order but for a different location then they won't be able to see the details of the saved credit card.
As of now, the guest cannot edit the existing Credit Card info. However, if they wish to delete the already existing Credit Card Details and add a new one, please follow the steps stated below :
Place an order online and tap on ""Pay Now"".
Tap on ""Dustbin icon"" displayed at the corner of existing card details. The card will be deleted.
Now tap on "ADD NEW PAYMENT METHOD" to add new card details and the new details will get added to the account.
