Block cards and visitor passes
How to block visitor passes so they can’t be used to sign in, and how to stop a lost, stolen or retired access card being used — and how to lift a block when a card is recovered.
A blocked card is a card added to your company’s Block Cards list so it can no longer be used to log in at a printer or MFD. The most common use is visitor passes — blocking a temporary visitor card once it has been handed back or has expired — but you can block any card that is lost, stolen, or no longer valid when you want to make sure nobody can use it.
Only the card is blocked. Blocking a card does not delete the person’s account or their other cards — it only stops that specific card.
Before you start
What you can do depends on the permissions on your role. If a button or option is missing, you don’t have that permission — ask your administrator.
| To do this | You need the permission |
|---|---|
| See the Block Cards list | View disabled cards |
| Block a new card | Add disabled cards |
| Edit a blocked card entry | Edit disabled cards |
| Unblock (remove) a card | Remove disabled cards |
Find the Block Cards list
Open your Company record. On the right, alongside the Pricing, Shared and Allowed tabs, select the Block Cards tab.
Companies › open your company › Block Cards tab
The list shows the cards currently blocked for your company, for example:
| User Name | Authentication |
|---|---|
| 0A1B2C3D | HID-Prox |
| 0A1B2C3D | RFID Card |
| 4E5F6071 | HID iCLASS/2 |
| 4E5F6071 | RFID Card |
| 8291A3B4 | HITAG 2/2 |
| 8291A3B4 | RFID Card |
Example data. Each card shows on two rows — its specific type and a generic RFID Card.
| Column | What it means |
|---|---|
| User Name | The card’s unique number/ID, as read from the card (e.g. 015C49F1). |
| Authentication | The card technology the entry applies to — e.g. RFID Card, HID-Prox, HID iCLASS or HITAG. |
Why each card appears twice. A blocked card is usually listed on two rows — once under its specific card technology (e.g. HID-Prox) and once as a generic RFID Card. This is normal and makes sure the card is blocked however a reader identifies it.
Block a card
- On the Block Cards tab, click + Add new record.
- Swipe the card on the Cirros card reader. The card’s number is read and fills in the entry automatically — you don’t type anything.
- Click Save.
- The card appears in the list and can no longer be used to sign in at your devices.
Tip. Have the physical card and a Cirros reader to hand before you start — swiping captures the exact card number, so there’s nothing to type and no risk of blocking the wrong card.
Stop visitor passes being used to sign in
Visitor passes are shared and temporary, so you don’t want them used to sign in at your devices. Add each visitor pass to the Block Cards list: once a card is on the list it is refused at sign-in — if someone taps it at a device, they are not logged in.
- Gather your visitor passes and a Cirros card reader.
- On the Block Cards tab, click + Add new record.
- Swipe a visitor pass on the reader — its number is captured automatically — then click Save.
- Repeat for every pass in the batch, so the whole set is blocked.
Tip. Block the whole batch of visitor passes in one go, as soon as you receive them — then leave them on the list. Don’t unblock a visitor pass, or it can be used to sign in again.
Good to know. Blocking controls sign-in. It doesn’t stop a card being added to a signed-in user’s account, but a blocked card still can’t be used to log in — so it can’t give anyone access. If a visitor pass was added to someone’s account by mistake, remove it from that account in the portal as well.
Unblock (remove) a card
If a card is found or needs to be used again, remove it from the list:
- Open the Block Cards tab.
- Find the card’s row (use the column filters or sort if the list is long).
- Select the row and choose Remove / Delete, then confirm.
To correct a mistake in an entry, use Edit on its row instead of removing and re-adding.
Good to know
- Swipe, don’t type. The card number is captured by swiping the card on the Cirros reader — there’s nothing to type in. You need the physical card to hand to block it.
- Blocking is per company. A block applies to the company you’re working in. A card blocked in one company is not automatically blocked in another.
- It doesn’t touch the user. Blocking a card doesn’t suspend or delete the cardholder’s account, PIN, or other cards — only the card you block.
