Subscribing and paying

Saved cards and standing authorisation

For fans — how a card ends up on file, what permission it carries, and how to have it taken off

Your card is saved as a side effect of buying something. The card goes on file the first time you type it into a purchase, and the sheet tells you so before you commit.

The two things that happen when you type a card

  1. The card is saved. The gateway keeps the card number; EVVA keeps a reference to it, plus the brand, last four digits and expiry.
  2. Standing authorisation is recorded. This is a separate act: saving a card means “hold this for me”, while standing authorisation means “charge it again without asking me”.

Standing authorisation is recorded before any money moves. It is what allows a subscription to renew, and what allows a free trial to be charged when it ends. Nothing else charges a saved card on its own.

Having a card taken off file

To have a saved card removed, or to withdraw the permission to charge it again, contact support at support@evvahub.com and say which account the card sits on. Otherwise a card stays on file until it expires.

You can also:

  • Stop what would charge it. A saved card is only charged again by something you started. Cancelling a subscription stops its renewals — see Cancelling a subscription.
  • Use a different card next time. Typing a card at a purchase saves that card too; the button that offers a card on file names the card it will use, so you can see which one you are about to be charged on.
  • Talk to your card issuer. They can block a recurring charge on their side.

Why a saved card is sometimes not offered

A card is offered as a one-press payment only once it is both reusable and has had at least one payment accepted on it. Until then you are asked to type the details.

A saved card is also refused at payment time — “That instrument cannot be charged” — when the card has expired, or when the standing authorisation needed for a charge made without you present is not in place. EVVA does not say which of those it is. In practice the way forward is the same either way: pay by typing the card details again, which saves the card and records the permission afresh.

What EVVA can see

The record of your card holds the brand, the last four digits and the expiry, plus whether it can be reused and whether a payment on it has ever been accepted. The card number itself goes from your browser to the payment gateway and is never sent to EVVA — a request carrying a card number is refused outright.
