Readers and credentials

QR and 2D code scanner

A QR and 2D scanner reads a supported code presented at an entrance or kiosk. The connected access system checks the credential’s validity and permissions before deciding the response; the scanner does not issue access rights.

Presentation matters

A code reader and a valid access credential are different things.

The scanner captures a supported QR or 2D code; the connected system evaluates the credential behind it. Plan the code source and validation rules along with the physical reader.

  1. Phone screen or printed ticket?

    Use only formats and presentation media supported by the selected scanner. Test the actual phone screens and printed documents at the mounting point, including glare, screen brightness, print quality and the angle available to the user.

  2. Can a copied code be used again?

    The scanner reads the presented code; reuse depends on the connected credential rules. If one-time use, expiry or cancellation is needed, configure and test those behaviors in the access system. Printing a QR code does not create those restrictions.

  3. Make the result clear at the entrance

    Separate unreadable codes from credentials that are read but refused. Define the feedback and assistance path for each case, then check that the approved scanner interface sends the expected information to the controller.

Printed and mobile codes

Make the code easy to present and read.

The scanner captures a supported code; the connected system evaluates what that code authorizes.

Code format
Use a symbology supported by the selected scanner and access system.
Presentation
Test paper and phone screens where those media are included, at the actual mounting position.
Access result
Expired, invalid and accepted codes need a defined response at the entrance.

Equipment details

Read a code at the access point

The scanner reads the code presented by the user; it does not issue the credential. The connected system checks the code and determines the access response.

Component or useHow it fits the system
On a phoneThe code is presented on the screen at the reader. Screen brightness, reflections and presentation angle are part of the reading conditions.
On paperThe printed code is presented at the same interaction point. Print quality and the condition of the document affect what the scanner can read.
Code validationThe access system evaluates the credential behind the code, including its validity and permissions under the configured rules.
User feedbackThe entrance workflow needs an understandable result after a scan and an assistance path if the code cannot be used.

Configuration: Speed, reading distance, environmental rating, supported formats and integration behavior depend on the selected model.
