# Managing customers' session cards (/en/businesses/shop/session-cards/managing-cards)

Staff manage sold cards from the session card's **Purchases** tab and the customer's **Session cards** tab.

## Editing a card customers already own [#editing-a-card-customers-already-own]

Customers' cards keep the name, description, quota type, maximum sessions and validity they were bought with. Editing the session card changes what the next buyers get. A change to the restrictions reaches cards already sold. See [Changes reach cards already sold](/businesses/shop/session-cards/where-cards-work#changes-reach-cards-already-sold).

To bring your edits to cards that are active or not yet started, open the session card and choose **More actions** → **Update existing purchases**, then tick the changes to copy.

- **Name and description** are copied as they are.
- **Quota type** keeps what was used. Three used sessions become three used hours.
- **Max sessions** raises the limit on cards below the new maximum. **No usage limit** removes the limit from every card.
- **Validity period** or **Validity in days** takes the session card's current setting, counted from the original purchase or first use.

Tell customers yourself when a change affects them.

## Tracking and correcting usage [#tracking-and-correcting-usage]

On the customer's **Session cards** tab, the card's **Usages** show what each use paid for. A refund returns the use to the card.

- **Void usage** returns a use, for example for a class the customer missed because of the venue.
- **Reactivate usage** deducts a voided use again.
- **Create usage** deducts sessions or hours for a visit that was not booked in Thril.

Staff can also pay an unpaid registration with the customer's card afterwards. See [Taking payment at the desk](/businesses/events/participants#taking-payment-at-the-desk).

## Changing one customer's card [#changing-one-customers-card]

Editing a customer's card changes only that card: its usage limit, **Valid from** and **Active until**. On a card whose validity starts on first use, clearing **Valid from** restarts the validity on the next use.

**Revoke session card** takes the card away from the customer.

## Granting a session card by hand [#granting-a-session-card-by-hand]

**Grant session card** on the customer's **Session cards** tab gives the customer a card without a purchase. It takes the session card's usage limit and expiry, or ones you set. The card is ready to use straight away.

Grant a card when the gift or compensation should pay only for what the card covers. [Credits](/businesses/shop/credits#what-credits-pay-for) pay for almost everything at the venue.
