Once they are installed just run:
|
|
|

To run any code you will also need to have installed the pcsc daemon:
|
|
|
|
apt-get install pcscd
|
|
|

Example
|
|
=======
|
|
|
|
var pcsc = require('pcsclite');
|
|
|
|
var pcsc = pcsc();
|
|
/* Check for new card reader detection */
|
|
pcsc.on('reader', function(reader) {
|
|
console.log('New reader detected', reader.name);
|
|
|
|
/* Check for reader status changes such a new card insertion */
|
|
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 */
|
|
} else if ((changes & this.SCARD_STATE_PRESENT) && (status.state & this.SCARD_STATE_PRESENT)) {
|
|
console.log("card inserted");/* card inserted */
|
|
}
|
|
}
|
|
});
|
|
|
|
/* You can connect to a smart card */
|
|
reader.connect(function(err, protocol) {
|
|
if (err) {
|
|
console.log(err);
|
|
} else {
|
|
console.log('Protocol(', this.name, '):', protocol);
|
|
/* And transmit data */
|
|
reader.transmit(new Buffer([0x00, 0xB0, 0x00, 0x00, 0x20]), 40, 1, function(err, data) {
|
|
if (err) console.log(err);
|
|
else console.log('Data received', data);
|

})
|
