Wrapper for SCardControl

I want to get a "reliable" connection to the smart card. Right now there is an option to specify either shared or exclusive access to a reader during connect(). Exclusive access is the best option, but it is not always possible in real life situations - some other system app keeps a an idle connection to the reader open, for example. For such situations SCard(Begin|End)Transaction could be used, together with a shared connection.

This is sometimes worse than a plain shared connection, as Windows 8+ have a "5 second rule" for transactions (see Remarks in MSDN: https://msdn.microsoft.com/en-us/library/windows/desktop/aa379469(v=vs.85).aspx)

There are at least two paths to a solution:

• expose SCard*Transaction calls on JS API level. This leaves the burden of transaction management to the app developer
• hide the complexity from app developer and add an option to connect() that would indicate "shared mode transactions", which would call SCardBeginTransaction on non-windows platforms, together with SCardConnect. And give a synthesized SCARD_E_SHARING_VIOLATION error if this fails for some reason.

From flexibility POV, the first option would be best, from ease of use and 'DWIM' interface POV, I would probably wrap the exposed transaction mechanism behind a connect() wrapper before use, anyway.

Hello,

We have some windows configuration where card events are not received after first card removal. This windows are dev PC with mixed middlewares installation (gemalto, charismathics, personnal, alladin, ...). Maybe it's related, or not. I try to investigate on this.

For now, I see that monitoring stopped when SCARD_STATE_UNAVAILABLE is set. On this PC this event is triggered on card removal, but reader is still connected. In first and very fast analyse I should remove the check on this flag, but I think there is good reason for it (On linux or mac OS maybe ?).

I do some more tests, and come back to you with more informations on our windows stations. (value of other flags and return code).

Thanks,

When I run the npm install pcsclite, it doesnt work

Some reader manufacturers provide closed API's to manage specific cards. Usually these API's need to access the SCARDHANDLE that references a specific connection. Exposing the handle allows to implement nodejs wrappers around these API's

Hello there

Is there any way we can simplify APDU sending and retrieving?
Working with the buffers seems to have quite a steep learning curve for folks who don't understand very much of the subject.

Hopefully a higher level API would be enough and more time saving for those who want this library to work.

The attached file below is an eID Belgian SDK doc, for example on how the APi could be structured

Below is an APDU.js file taken from the Open Smart Card Development Platform ( http://www.openscdp.org/index.html)

Hi all,

I'm probably just being a noob here but getting a node-gyp error when trying to install.

This looks like it's an error not having libpcsclite-dev package. But I'm not seeing that package available for osx (brew or macports)

Can anyone confirm this is the issue I have? Where I can install the pcsc dev packages? Anything helps, thanks!

I am using ACR1252U-A1 for reader. I cannot do any transmit operations succesffully but I cannot get any response by using control command.

What I tried is

reader.control(new Buffer([0xE0, 0x00, 0x00, 0x18, 0x00]), 3500, 30, function(err, data)[
  console.log(data) // undefined
});

Hello,

First of all thanks for providing this wrapper,
I am trying to use it in a node-webkit application, however app is crashing everytime node-pcsclite,

At the moment i've been trying basic code, and even with the example you provide on the project page I am getting the following error :

nwjs Helper(955,0x7fff716c8180) malloc: *** error for object 0x7f8649476058: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug

Right before getting this message, and on the first time usage, everything is working great. but then it crashs, and keep crashing until I purge computer memory.
As I say for the moment the app is just a basic try, the application is not doing anything else but testing the example code.

Not sure what can I do to help.

Thanks

Basically this is the example code i have used, other examples gives me the same result at the end.

`#!/usr/bin/env node
var pcsc = require('./lib/pcsclite');
var pcsc = pcsc();
pcsc.on('reader', function(reader) {

function exit() {
    reader.close();
    pcsc.close();
}

cmd_select = new Buffer([0x00, 0xA4, 0x04, 0x00, 0x0A, 0xA0, 0x00, 0x00, 0x00, 0x62, 0x03, 0x01, 0x0C, 0x06, 0x01]);
cmd_command = new Buffer([0x00, 0x00, 0x00, 0x00]);

console.log('Using:', reader.name);

reader.connect(function(err, protocol) {
    if (err) {
        console.log(err);
        return exit();
    }
    reader.transmit(cmd_select, 255, protocol, function(err, data) {
        if (err) {
            console.log(err);
            return exit();
        }
        console.log('Data received', data);
        reader.transmit(cmd_command, 255, protocol, function(err, data) {
            if (err) {
                console.log(err);
            } else {
                console.log('Data received', data);
                console.log('Data received', data.toString());

            }
            return exit();
        });
    });
});
});

pcsc.on('error', function(err) {
  console.log('PCSC error', err.message);
});`

But no matter which card i used it gives the same response (Mifare Ultralight and Mifare 1k classic)

Using: ACS ACR122 0
Data received < Buffer >
Data received < Buffer >
Data received

I have not idea what is going on with this.
Im using Windows 10, everything seems to be builded successfully.

Running the examples/example.js example I get:

Protocol( undefined ): 2

The corresponding source code is:

            console.log('Protocol(', this.name, '):', protocol);

I guess the plan was to display "T=0" or "T=1" depending on the negociated protocol.

Hi Santi,

I'n trying to compile node-pcsclite on a Macosx (10.9.4) without any success so far. I'm not an expert on node-gyp much less on pcsc so forgive me in advance for any wrong or inaccurate information.

Looking at you binding.gyp file and comparing it with other related projects like node-pcsc I could manage a few things to aid in the process of making your lib properly compile in other platforms.

1- declare the proper conditions for other platforms similar to this binding.gyp.

2- Fixed references to winscard.h with the guidance of @LudovicRousseau to include PCSC/winsdcadr.h instead of just winscard.h

UPDATE:Now I'm stuck with the compiler not finding nan.h in my platform. Any ideas?

3- Referenced Nan in all platforms.

Now I'm getting errors with due to calls using unsigned long pointers instead of to uint32_t. From here I'm not sure if is safe to just change the type or if I should be aware of any type incompatibility. Any ideas?

Sorry if this is in the wrong place, this does not seem to be a pcscLite issue, but one with the example code for the node bindings, or perhaps my understanding of things. I'm pretty new to APDU and smart cards in general.

I have two different smart cards from (presumably) two vendors. I don't know for sure because there's no indication on either card, but they're issued by two different organizations, so I'm making an assumption that they're different. In any case, let's call them Card A and Card B.

Using the sample code provided in this module, Card A inserted into a card reader will receive the transmit buffer of [0x00,0xB0,0x00, 0x00, 0x20] and respond with its own buffer array. I haven't gotten to where I can make use of the response yet beyond printing the hex to the screen, but that's part of my learning curve and I accept it.

Card B, however, running the same code on the same host in the same card reader, responds with 'SCardTransmit error: Transaction failed. (0x80100016)'. Note that this card works fine with company-provided applications (e.g. signing & encrypting emails, etc), so it's not a faulty card.

Any thoughts on how to proceed?

I am not sure to love call backs so much. Sometimes a synchronous API is fine, especially when you want to send a sequence of APDU and have nothing better to do.

Do you plan to also provide a synchronous version like it is the case for File IO API?

Hi there nice project...

Is this project goal to enable client side javascript to access client-connected pcsc devices?

I mean, it runs on node.js at the server, but the javascript at local client would be able to connect to SmartCard readers connected to client computer (running browser) ?

Does this work on windows?

Hello,
I try to use node-pcsclite with electron to make a desktop application.
if I use only node-pcsclite, it's works.
but as soon I add "var pcsc = require('pcsclite');" in the main.js of the electron main file, I get this error:
Error: Cannot find module './build/Debug/buffertools.node'

I find this issue, but I do not understand how to fix the problem, in my case it does not even work on the developement computer.
Can you help me,
I'm running Ubuntu 14.04 LTS 64

Hi,
I am trying to connect to the reader with direct mode to write on LCD. It works on Linux, but not on Windows. Are the drivers different?

var LCD_CONTRAST = new Buffer([0xFF, 0x00, 0x6C, 0x00, 0x00]);

clearScreen: function (reader) {
    reader.connect({ share_mode: reader_object.SCARD_SHARE_DIRECT }, function (err, protocol) {
        reader.transmit(LCD_CLEAR, 40, reader.SCARD_PROTOCOL_RAW, function (err, data) {
            if (err) {
                console.log('error clearing screen:', err);
            }
        });
    });
}

I get [Error: SCardConnect error: Smart card was removed <0x8010069>] while trying to connect.

Cheers,

jokesterfr/node-pcsc#10 (comment)

by @jokesterfr

Hi,

I've noticed that whenever I disconnect my reader the library does emit end as intended to notify about reader removal. But once the reader is plugged back in the reader message is never emitted again?

Shouldn't there be a message when a reader is detected?

Using latest release 0.5.0 on Linux.

Thanks for your help.

Hi,

We will start a new project using your really nice library. Since we are going to use Typescript as our language of choice I sat down and wrote the typings. I asked myself if you would like to incorporate these typings in your project or if you would rather like to see them in the DefinitelyTyped-repository.

They may be not yet perfect but they work ;)

Just let me know if I should create a PR.

According to the "documentation" https://github.com/santigimeno/node-pcsclite#event--status the status event should be sent "whenever the status of the reader changes".

If I use the sample code I get:

$ node examples/example.js 
New reader detected ACS ACR122U PICC Interface 00 00
Status( ACS ACR122U PICC Interface 00 00 ): { state: 34,
  atr: <SlowBuffer 3b 8f 80 01 80 4f 0c a0 00 00 03 06 03 00 01 00 00 00 00 6a> }
card inserted
Protocol( undefined ): 2
Data received <SlowBuffer 63 00>

Here I remove the card

Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }
card removed
Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }
Disconnected
Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }
Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }
Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }
Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }

Here I get hundreds of duplicate log lines

Status( ACS ACR122U PICC Interface 00 00 ): { state: 146, atr: <SlowBuffer > }
Status( ACS ACR122U PICC Interface 00 00 ): { state: 18, atr: <SlowBuffer > }

Also the sample code should not have to use:

var changes = this.state ^ status.state;
        if (changes) {

to detect a status change if the status event is sent only when the status changes.

I run the sample code on Mac OS X Mavericks.

npm install pcsclite..

Hello,
I have done some evaluation on you pcsc library and it looks perfectly suited for mine need from the functional point, but I have hit on one big issue.

I'm unable to build your pcsclite application on Windows 7 x64/ia32 when using nwjs v0.13.4 (the latest stable version). I have been playing quite long with this topic and have found that I'm able to build it for nwjs version v0.13.0-beta7.

I'm using Visual Studio 2013

On Mac is workign eveything fine.

Working command
cd node_modules\pcsclite
nw-gyp rebuild --target=0.13.0-beta7 --arch=ia32

Error command
cd node_modules\pcsclite
nw-gyp rebuild --target=0.13.4 --arch=ia32

Error message:
gyp ERR! stack Error: C:\Program Files (x86)\MSBuild\12.0\bin\msbuild.exe failed with exit code: 1

Please can you advice ?

Thanks a lot.

How can i get uid (unique ID) of NFC tag? Help me please!

I have a use case where I have to forward ADPU commands from one device to a remote card to perform an authentication procedure. During the authentication process I have to switch from T0 to T1 or from T1 to T0.

Problem is that if I try to change the protocol between two ADPU commands I get a protocol mismatch exception. Any thoughts on this would be highly appreciated !

Hey,
node-pcsclite was working on monday with NaN 1.4.1, today it's not working anymore with NaN 1.5.1.
I suggest setting the exact dependency in the package.json ;)

Hi,
I'm just starting to learn smartcards systems and run into a problem. I have an HID Omikey 5321 CR on OSX El capitan. I installed the drivers from HID for osx. and try to run the exemple code from the node node-pcsclite.
The reader is recognized, and I can read the atr :

card inserted
Protocol( OMNIKEY CardMan (076B:5320) 5321 ): 2
Status( OMNIKEY CardMan (076B:5320) 5321 ): { state: 290,
atr: <Buffer 3b 8f 80 01 80 4f 0c a0 00 00 03 06 03 00 01 00 00 00 00 6a> }

but when it comes to send an APDU it keeps returning me

 [Error: SCardTransmit error: Transaction failed.(0x80100016)]

From the HID device documentation :

Reading all 15 blocks from 0 to 14
Command APDU: ‘FFB0000000’
Response APDE: ‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx9000’
Attempt to read 16 blocks
Command APDU: ‘FFB0000010’
Response APDE: ‘xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx6282’

so I use

reader.transmit(new Buffer([0xFF, 0xB0, 0x00,0x00, 0x00]), 255, protocol, function(err, data) {
... }

But still the same error.

There is surely some steps i missed, so can anyone Help me ?

Thanks in advance

npm ERR! Test failed.  See above for more details.
npm ERR! not ok code 0

The problematic code is like connect_cb(undefined, 1);
It looks like undefined is not correct here. I do not know node-js enough to propose a patch.

One functionality smart card developers need to implement on top of PC/SC style "BIBO" (Bytes-In, Bytes-Out) interface is often ISO 7816-4 based T=0 response handling for 6CXX (GET RESPONSE) and 61XX (fixed Le) handling. So instead of making another 20 line npm module for the usability improvement, it would be great if the functionality was traight in node-pcsclite, for those small scritps that build straight on top of node-pcsclite and do not want/need some heavier layer above it. Will make a PR if that sounds reasonable.

As commented by @jokesterfr at #2 (comment)

Error installing with nodejs on windows OS.

E.g. readers that are "never inserted" and therefore are not detected by on("reader").

I am a bit confused about cleanly closing the runtime after I am done with the reader I am interested in.

There is reader.disconnect() which is a wrapper around SCardDisconnect(), thus I obviously call it.

Then there is reader.close() which is intended to call SCardCancel() (for this specific reader?). I call it and get no errors.

Then there is pcsc.close() which is intended to also call SCardCancel() (for PnP reader tracking?). I call it and get an error event on pcsc: SCardGetStatusChange error: Command cancelled.(0x80100002). And the node process does not exit after this call. AFAIU SCardGetStatusChange should never emit an error if it is cancelled (I suspect this is a bug)

Two questions:

• How do I properly clean up the runtime, without calling process.exit()?
• Why are there two status checkers? AFAIU one call for SCardGetStatusChange should be sufficient, also for getting events for the pnp pseudo-reader as well as any connected readers, to be able to emit reade events (thus a pcsc.close() should be sufficient, and should result in normal exit of nodejs runtime?)

There seems to be a bunch of unused/closed/stale branches on Github, that could be cleaned up for those who run git branch -a on their development boxes.
