Bindings over pcsclite to access Smart Cards

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 */

                console.log("card inserted");/* card inserted */
            }
        }
    });

    /* You can connect to a smart card */

            /* And transmit data */
            reader.transmit(new Buffer([0x00, 0xB0, 0x00, 0x00, 0x20]), 40, 1, function(err, data) {
