Can I ask for credit card details without taking payment? I wish to charge the customer card at a later stage.

Yes, you can ask for credit or debit card details without charging the card at the time of the booking. The sensitive information will be safely stored on Stripe servers and you can debit the card at a later stage.

This can be used as well for "no-show": if a customer does not show up and you need to charge him for a certain amount as per your terms and conditions.

Note that this feature is only available with Stripe gateway.
