# Developing Your Visionline Plastic Card Encoding App Using a Real Visionline Server

> Learn how to use a Real Visionline server to develop your Visionline plastic card encoding app.

You can use an unlicensed Visionline account to develop and test your Visionline plastic card encoding integration. Then, you can launch your app into production using a real Visionline site.

<Info>
  There are some differences between using an unlicensed Visionline account and
  using a real, production Visionline site. Consequently, when you are ready to
  launch your app to production, make sure to follow the [instructions for
  launching](/device-and-system-integration-guides/assa-abloy-visionline-access-control-system/visionline-acs-setup-instructions/developing-and-launching-your-visionline-plastic-card-encoding-app/launching-your-visionline-plastic-card-encoding-app-to-a-live-site/index).
