If the customer selects the "Delete card", the data on the current map will be deleted immediately. To remove the other card's information, you must first select an action "Another card" then select card for deletion and then delete the current card.
When there are no cards left after deletion then full information of a new card must be provided in a payment. Also, the customer will again receive an offer to save the card for the next purchases using the One Click service. For a complete refusal of participation in the program the customer should contact the merchant.
