# Open the Door via Encrypted QR Codes

Akuvox devices can scan AES-encrypted QR codes for door opening. This allows you to generate and control QR codes on your own servers, encrypting them before transmission to protect sensitive information from unauthorized access.

> [!NOTE]
> Compatible models and versions(or higher):
> 
> - A08: 108.30.11.19
> - X915V2: 2915.30.10.408
> - X912: 912.30.11.215
> - X910: 2910.30.11.21
> - S532: 532.30.10.272
> - E16V2: 216.30.11.25
> - E16V3: 416.30.11.206
> - E18: 18.30.10.247
> - R20: 320.30.12.19

For example, the key value of the QR code below is 81234567 before encryption. Assign the key to a specific user for door opening.
