Generating QR codes

You can generate QR codes in your document using the 2D Barcode → QR Code component.

The QR code content is defined using a data expression.

How it works​

  • QR codes encode text data
  • You provide the content using an expression
  • The QR code is generated during document rendering

Example:

CONCAT("https://example.com?id=", orderId)

Important concept​

Eledo does not interpret QR code types directly.

Instead, it encodes the provided text.
Different QR code “types” are simply different text formats.

Common QR code formats​

You can generate various types of QR codes by formatting the encoded text correctly.
