Scan their pass and check the **Last stamped:** line, shown just above **Hold to stamp**. If it doesn't mention this visit, the stamp genuinely didn't go on.

## Most likely fix

1. Scan the member's pass again to open the Stamp Card.
2. Read **Last stamped:**. If it's not from just now, hold **Hold to stamp** again — there's no limit on how many stamps a visit can have.
3. Check the stamp count went up by one.

## If that didn't work

- **The Stamp Card is switched off.** No stamps are given out while it is, and members don't see a card — see [How do I stop the Stamp Card?](https://help.useflub.com/your-club/stamp-card-end.md), which also says how to switch it back on. A card that was paused or ended before those buttons went also reads as off, and switching it on starts it again.
- **The club has closed.** A closed club doesn't give stamps, and staff see "This club isn't stamping right now." Reopen it from **Account** to start again: see [Can I close just one of my clubs?](https://help.useflub.com/account/close-a-club.md)
- **Staff pressed Undo by mistake.** Undo only works within a minute of the stamp, and it's meant for exactly this — a mis-tap. Past that minute, a stamp can't be added back or taken away from here.
- **They're not a member of your club any more, or their membership's paused.** Neither can collect stamps — see [What happens when a member uses their pass at the counter?](https://help.useflub.com/members/counter-redemption.md)
