### Reader compatibility and badge reader support

Verkada access control units are compatible with readers that output Wiegand and Verkada’s [door reader](https://www.verkada.com/door-reader/ad32/) (OSDP).

{% hint style="warning" %}
See [Badge Reader Support](https://help.verkada.com/access-control/installation/badge-reader-support) for more information.
{% endhint %}

### Cardless option

Want to go cardless? Ask your employees to download the [Verkada Pass](https://help.verkada.com/access-control/users-and-credentials/verkada-pass-app) app (available on [iOS](https://apps.apple.com/us/app/verkada-pass/id1477261074) and [Android](https://play.google.com/store/apps/details?id=com.verkada.VerkadaPass\&hl=en_US)) to open doors via their phone. No badge required.

### Verkada MIFARE DESFire EV3

The MIFARE DESFire EV3 [card format](https://docs.verkada.com/docs/encrypted-cards-datasheet.pdf) is supported.

## Limitations and workarounds

### Indala cards

{% hint style="danger" %}
The Verkada [AD33](https://www.verkada.com/door-reader/ad33/) door reader does **not** support [HID iCLASS](https://www.hidglobal.com/product-mix/iclass) or Indala cards. You must use a third-party reader that advertises this compatibility.
{% endhint %}

* Indala cards work on the Indala readers.
* HID iClass cards work on iClass-compatible readers as long as the AC41 supports the underlying format.

### MiFare card (MiFare classic, 4 bytes/32-bit)

* The Verkada [AD33](https://www.verkada.com/door-reader/ad33/) door reader reads the Card Serial Number (CSN).
* The Wiegand reader reads the card number.

In the event of a switch between Wiegand readers to Verkada AD33, the cards need to be re-scanned.

### Schlage and Assa Abloy Aperio wireless lock integrations

The Verkada Prox cards are supported; however, the Verkada DESFire EV3 cards do not work with these integrations.
