Ubuntu/MAC Smart Card Operation overview 1-access PC/SC Card Reader

Because PC/SC is a Windows system, it serves applications at the system API level. So for a long time, card readers and tools related to smart cards have been concentrated on Windows, while on Unix systems, card readers have been reluctant to accept. Fortunately, with the open-source organization m.u. s. c.l. with the active efforts of E (movment for the use of smart in Linux environment), pcsclite has become a de facto standard for the PC/SC device framework and application interfaces under xnix, the Mac lion system has already integrated this service in the release version. The following uses the Ubuntu 12.0.4 release as an example.

 

# First install the pcsc daemon pcscd and tools

Sudo apt-get-y install libusb-Dev

Sudo apt-get-y install pcscd

 

# Then install a card reader driver that supports pcsc (for example, the built-in ACR acs38u, and other card readers can download and install it on the website)

Sudo apt-get-y install libacr38u

 

# Connect the card reader, plug the card, and run the scan tool to verify the installation result

Pcsc_scan

The result is as follows:
PC/SC device restart

# So far, the PC/SC driver has been connected. Now let's try to send an APDU

Sudo apt-get-y install pcsc-Tools

Gscriptor

This is a graphical interface tool. In the script box, enter:

# Congratulations, card access is successful. Now you must be impatient. Do you want to create your own applications?

# Install the Development Library

Sudo apt-Get install libpcsclite-Dev

# Install eclipse CDT as the development environment

Sudo apt-get-y install g ++
Sudo apt-get-y install eclipse-CDT

# Open eclipse, create a new C Project, and add

# Include <pcsc/winscard. h>

# Link to the pcsclite Library: Add pcsclite in C/C ++ build/GCC linker/Libraries

# Now you will be happy to find that the Type Definitions and interfaces provided in winscard. h are the same as those provided in windows. We copy a section from WindowsCodeCome here:

Success! Next, I will talk about the configuration based on the javacard environment and tool on Ubuntu, so stay tuned.

 

Note:

The header file of libpcsclite on Ubuntu is located in/usr/include/pcsc by default. multiple directories are added. Some versions may have # include file errors during compilation. You can modify them as follows:

Sudo Vim/usr/include/pcsc/winscard. h

Change # include <pcsclite. h> to # include <pcsc/pcsclite>, save and exit

Sudo Vim/usr/include/pcsc/pcsclite. h

Change # include <wintypes. h> to # include <pcsc/wintypes. h>.
