PCSCCheck, the all-in-one tool to validate and tune your PC/SC installation

An analysis of the questions that are the most frequently asked to our technical support shows that many issues and concerns are due to the settings or the behaviour of Windows operating system itself.

This is particularly the case in security-enforced corporate environments, where strict administrative policies may prevent the user to install the right driver, or even prevent the applications to access local smart card readers.

The fact that Windows raises a couple of notifications ("Setting up a device", then "The smart card requires drivers that are not present on this system") every time a card is inserted in a PC/SC reader for the first time is also the source of many questions, that this article will address.

How to be sure that the SpringCard PC/SC driver is installed on Windows?

Since all SpringCard USB PC/SC couplers comply with the USB CCID specification, they are supported by the generic CCID driver supplied by Microsoft as a part of the Windows operating system. As a consequence, when connecting a SpringCard PC/SC coupler to a computer for the first time, this coupler is associated to the generic "Microsoft Usbccid Smartcard Reader (WUDF)" driver by default.

This is a problem for many users, since this generic driver has many limitations that make it un-suitable for most of the use cases.

In this article, we'll expose its 3 most obvious limitations, and expose the 2 different methods to installing the right driver.

Securing the connection to the MQTT broker using TLS and SpringCore client certificates

The aim of this tutorial is to configure a SpringPark as a Network SmartReader/MQTT client with a mosquitto broker. The SpringPark in this configuration acts as an MQTT client (using TLS). It sends its tags to the mosquitto broker hosted at mqtt.springcard.com. 

For this howto, we will assume that:

  • your SpringPark is using a default (from factory) configuration.
  • you have some networking basis.
  • you have some MQTT basis.

How to setup and use a SpringPark as an Amazon AWS client

The aim of this demonstration is to configure a SpringPark as a Network SmartReader/AWS client. The SpringPark in this configuration acts as an AWS IOT Core client (using TLS). It sends its tags/informations to Amazon's cloud and can also receive commands.

We won't cover the AWS's side (lamba function, certificates, policies, ...) but focuse on the device's side.

For this howto, we will assume that:

  • your SpringPark is using a default (from factory) configuration.
  • you have some networking basis.
  • you have some MQTT basis.

How to setup and use a SpringPark as a SmartReader over TCP

The aim of this tutorial is to configure a SpringPark as a Network SmartReader. The SpringPark in this configuration acts as a TCP server (default factory port is 4000) and sends its tags to the client connected to this port.

For this howto, we will assume that:

  • your SpringPark is using a default (from factory) configuration.
  • you have some networking basis.

Our SpringPark will output tag information using the SCRDR format (cf. SCRDR Protocol).
