Three Important QR Code Workflows
1. Parking Ticket Identification
A printed parking ticket contains a QR code or barcode linked to a parking record.
The driver presents the ticket to the scanner. The kiosk application retrieves the associated parking information from the parking management system.
2. Customer-Presented Payment Code
The customer presents a supported payment code on a mobile device.
The scanner reads the code, and the approved payment application processes it through the relevant provider.
3. Merchant-Presented Payment QR Code
The kiosk displays a transaction-specific payment QR code.
The customer scans it using a compatible payment application, and the kiosk receives payment confirmation through the configured software integration.
These workflows require different software arrangements even when they use similar QR technology.

Lighting Conditions
Bright sunlight, reflections and low-light conditions can affect scanning performance.
Installation Position
The scanner must be placed at a comfortable height and angle, with sufficient clearance for tickets or smartphones.
Communication Interface
USB, serial and other supported interfaces should be matched to the industrial computer and application.
Environmental Protection
Outdoor scanner openings require suitable protective design and maintenance access.
