Getting Started

Main Concept#

  1. The free mobile application scans a bar code or qr code
  2. The value of the scanned code is sent to URL you set.
  3. Based on the response from your endpoint, a green/red screen (with optional custom message) is shown. Sound signal is also played.

Steps#

Configure the App#

You configure your URL endpoint and other settings by creating a config JSON document. This JSON document needs to be converted to a QR code and scanned by the mobile application. When the application scans this special QR code, it applies and stores the settings.

Please see details on the settings JSON document .

A web-application will be developed that will facilitate creating of the JSON settings file.

Try scanning QR code in this page and view results realtime in public AIR table:

Distribute to users#

You can distribute the device with pre-configured settings to end users, who will use the mobile app to check & scan codes. Or you can instruct them to scan a QR code you send them by email or text message to initialize the application.

Each device installation has unique deviceId identifier assigned, that is sent with each API request. It is also possible set custom headers of the API request, e.g. a API key or any custom identifier.
