FAQ of QR Code Image Reader
1. What is a QR code Imagereader?
A QR code access control is a digital key that replaces physical keys or access cards. You simply scan it from a phone or a printout to unlock doors, with permissions managed entirely in the cloud.
Its main advantage lies in flexibility: access rights can be set to expire after a specific time, limit the number of entries, or restrict access to certain doors.

2. How does QR code Image reader work?
The system consists of three components:
> Reader: A QR code reader installed at the door, connected to the controller.
> Credential: A QR code displayed on a mobile app, email, or printed badge.
> Validation: The reader scans the code, decrypts the data, checks permissions against the database, and triggers the door relay if authorized.

3. Can QR code image reader be tricked by printed copies?
Yes, but this is often intentional. Printed QR codes are commonly used for:
> Visitor passes: Printed on paper with expiration dates, often limited to single-use or specific time windows.
> Contractor access: Temporary credentials that self-destruct after the job ends.
> Contractor access: Temporary credentials that self-destruct after the job ends.
For employee access, dynamic app-based codes are the standard. If your system uses printed codes for employees, it's a security risk.
