A saved card on your account
Account settings has a payments page, and it shows the card you paid with: the last four digits and the expiry date. The card number is not shown there because it is not held here — Peelpel has no field that can hold one.
A saved card saves typing on the next booking. You can pay with a different card any time, and you can remove the saved one.
If you are shown a screen asking for card details in Peelpel's name, and it is not the payment form on the booking screen of Peelpel's site or app, it is not ours. Do not fill it in, and tell us.
