Install it from your own distro. For the Debian users:
apt-get install nodejs nodejs-legacy
Use nodesource repository for different distros.
In order to install the package you need to have installed in the system the pcsclite libraries. For example, in Debian/Ubuntu:
apt-get install libpcsclite1 libpcsclite-dev
Once they are installed just run:
npm install pcsclite
npm install เฉยๆ จะinstall module ต่างๆให้ เวลา download file from github
To run any code you will also need to have installed the pcsc daemon:
apt-get install pcscd
var pcsc = require('pcsclite');
var pcsc = pcsc();
pcsc.on('reader', function(reader) {
console.log('New reader detected', reader.name);
reader.on('error', function(err) {
console.log('Error(', this.name, '):', err.message);
});
reader.on('status', function(status) {
console.log('Status(', this.name, '):', status);
/* check what has changed */
var changes = this.state ^ status.state;
if (changes) {
if ((changes & this.SCARD_STATE_EMPTY) && (status.state & this.SCARD_STATE_EMPTY)) {
console.log("card removed");/* card removed */
reader.disconnect(reader.SCARD_LEAVE_CARD, function(err) {
if (err) {
console.log(err);
} else {
console.log('Disconnected');
}
});
} else if ((changes & this.SCARD_STATE_PRESENT) && (status.state & this.SCARD_STATE_PRESENT)) {
console.log("card inserted");/* card inserted */
reader.connect({ share_mode : this.SCARD_SHARE_SHARED }, function(err, protocol) {
if (err) {
console.log(err);
} else {
console.log('Protocol(', reader.name, '):', protocol);
reader.transmit(new Buffer([0x00, 0xB0, 0x00, 0x00, 0x20]), 40, protocol, function(err, data) {
if (err) {
console.log(err);
} else {
console.log('Data received', data);
reader.close();
pcsc.close();
}
});
}
});
}
}
});
reader.on('end', function() {
console.log('Reader', this.name, 'removed');
});
});
pcsc.on('error', function(err) {
console.log('PCSC error', err.message);
});
The PCSCLite object is an EventEmitter that notifies the existence of Card Readers.
Event: 'error'
err Error Object. The error.
Event: 'reader'
reader CardReader. A CardReader object associated to the card reader detected
Emitted whenever a new card reader is detected.
pcsclite.close()
It frees the resources associated with this PCSCLite instance. At a low level it calls SCardCancel so it stops watching for new readers.
The CardReader object is an EventEmitter that allows to manipulate a card reader.
Event: 'error'
err Error Object. The error.
Event: 'end'
Emitted when the card reader has been removed.
Event: 'status'
status Object.
state The current status of the card reader as returned by SCardGetStatusChange
atr ATR of the card inserted (if any)
Emitted whenever the status of the reader changes.
reader.connect([options], callback)
options Object Optional
share_mode Number Shared mode. Defaults to SCARD_SHARE_EXCLUSIVE
protocol Number Preferred protocol. Defaults to SCARD_PROTOCOL_T0 | SCARD_PROTOCOL_T1
callback Function called when connection operation ends
error Error
protocol Number Established protocol to this connection.
Wrapper around SCardConnect. Establishes a connection to the reader.
reader.disconnect(disposition, callback)
disposition Number. Reader function to execute. Defaults to SCARD_UNPOWER_CARD
callback Function called when disconnection operation ends
error Error
Wrapper around SCardDisconnect. Terminates a connection to the reader.
reader.transmit(input, res_len, protocol, callback)
input Buffer input data to be transmitted
res_len Number. Max. expected length of the response
protocol Number. Protocol to be used in the transmission
callback Function called when transmit operation ends
error Error
output Buffer
Wrapper around SCardTransmit. Sends an APDU to the smart card contained in the reader connected to.
reader.control(input, control_code, res_len, callback)
input Buffer input data to be transmitted
control_code Number. Control code for the operation
res_len Number. Max. expected length of the response
callback Function called when control operation ends
error Error
output Buffer
Wrapper around SCardControl. Sends a command directly to the IFD Handler (reader driver) to be processed by the reader.
reader.close()
It frees the resources associated with this CardReader instance. At a low level it calls SCardCancel so it stops watching for the reader status changes.
