Getting started with SpringCard Companion

SpringCard Companion is the new all-in-one solution to manage, configure and update the latest generation of SpringCard “SpringCore” devices (Puck, SpringPark, etc). SpringCard Companion is an hybrid application that combines a clean, efficient and always up-to-date web front-end with a tiny local software, the Companion Service, that is the gateway between the cloud and the devices connected to your computer or local network.

As such, the Companion Service is also the base component to connect any application built for the web with the ‘physical world’ of PC/SC couplers and Smart Readers, using only simple WebSocket and REST API calls.

Before you start using SpringCard Companion Web application (available at you should install the Companion Service on a Windows computer.

Not using Windows? use the SpringCore Tools to get the best of your SpringCore devices even without the Companion.

Setup SpringCard Companion Service


  • Windows 10 (or later), 64 bits edition,
  • Microsoft .NET Framework version 4.8 (or later),
  • AMD64 / X64 platform, with at least 4 CPU core and 8GB of RAM,
  • 20MB of hard drive,
  • Web browser: Chrome, Firefox, Edge or Safari (only most recent versions, see the Browser support page at for more details).

Choosing the installation ‘flavour’

Before running the installer, you should take a few minutes to consider how the SpringCard Companion Service will be used on this computer.

There are 3 ‘flavours’.

Flavour 1: single user, tray application

If you are this computer’s only (or main) user, choose “Install for me only”.

The SpringCard Companion Service will then run in a windowed application that sits in the system’s tray bar. You may also launch it manually only when you need to access the devices from the Companion Web app, and leave it idle the rest of the time.

To select Flavour 1, choose “Install for me only” on SN20030’s first screen.
In Flavour 1, SpringCard Companion Service tray shows a minimal menu. Note that the “Options” menu item does not require administrative privileges.

Flavour 2: all users, tray application

In case the computer is shared among many users and you want that SpringCard Companion Service runs in the system’s tray bar, choose “Install for all users”, then “Run Companion Service in the Tray application, inside user’s sessions”.

NB: installing for all users is possible only with elevated privileges. If your current account is not a system administrator, Windows will prompt you to enter an administrator’s login/password to run the setup.

To select Flavour 2, first choose “Install for all users” on SN20030’s first screen…
… then “Run in the Tray” after having selected the components.

In this flavour, users are still allowed to start/stop the SpringCard Companion Service according to their needs.

In Flavour 2, the software’s options are shared among all users, hence the “Global options” menu item that does require administrative privileges.

Flavour 3: system service

Installing the SpringCard Companion Service as an actual system service is the best choice for unattended machines (kiosks, ATM, etc.) or when deploying a specific software that relies on the Companion Service to access the devices.

To select Flavour 3, first choose “Install for all users” on SN20030’s first screen…
… then “Run as a system background service” after having selected the components.

In this flavour, only administrations could start/stop the SpringCard Companion Service, as this is the case with any other system service.

In Flavour 3, the “Global options” menu item and controlling the service that runs in background both require administrative privileges.

Unattended installations

In large organizations, system administrators would typically deploy the Companion Service on all (or at least many) computers from a global policy; for kiosks, ATM, etc., scripts are used to automate the deployments as well.

The SN20030 installer is specifically tailored to support the need of unattended installations. The setup supports specifying the ‘flavour’ on its command line.

For flavour 1, use


For flavour 2, use


For flavour 3, use


Use the /HELP flag on the command line to see all other available options:

SN20030 help screen for command line options.

Changing the flavour afterwards?

It is not possible to change the flavour only by running the setup again.

Basically, if the setup is runned without parameters, it will update (or downgrade) the software while keeping the existing installation flavour. If a /FLAVOUR= parameter is specified on the command line that is different to the existing installation flavour, the setup will exit with an error.

Error message when the specified /FLAVOUR parameter is not equal to the existing installation flavour.

Should you need to setup a different flavour, please uninstall the software first, then install it again with the new flavour.

NB: to perform an unattended uninstallation, run unins000.exe /SILENT in the program’s installation folder (namely C:\Program Files\SpringCard\Companion\Service).

Access SpringCard Companion Web application for the first time

Make sure the Companion Service is running

At the end of the installation process, the SN20030 installer offers to launch the tray application (even in flavour 3, since the tray is a convenient UI to the service, even if the service actually runs in background).

Leave the “Start SpringCard Companion Service Tray immediately” when finishing.

The Companion Service Tray’s splash screen is shown briefly:
