Install

npm install node-nfcpy-id

Settings for Raspbian with SONY Pasori RC-S380

sudo apt-get install python-usb python-pip -y
sudo pip install -U nfcpy
cat << EOF | sudo tee /etc/udev/rules.d/nfcdev.rules
SUBSYSTEM=="usb", ACTION=="add", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="06c3", GROUP="plugdev"

Please restart once.

sudo reboot

Examples

loop mode

'use strict';

const NfcpyId = require('node-nfcpy-id');
const nfc = new NfcpyId().start();

nfc.on('touchstart', (card) => {
  console.log('Card ID: ' + card.id);

  // card.type is the same value as that of nfcpy.
  // 2: Mifare
  // 3: FeliCa
  // 4: Mifare (DESFire)
  console.log('Card Type: ' + card.type);
});

// If the `mode` is `loop` or `non-loop`, event will occur when the card is removed
nfc.on('touchend', () => {
  console.log('Card was away.');
});

nfc.on('error', (err) => {
  // standard error output (color is red)
  console.error('\u001b[31m', err, '\u001b[0m');
});

non-loop mode

'use strict';

const NfcpyId = require('node-nfcpy-id');
const nfc = new NfcpyId({mode: 'non-loop'}).start();

nfc.on('touchstart', (card) => {
  console.log('Card ID: ' + card.id);
  console.log('Card Type: ' + card.type);
});

// If the `mode` is `loop` or `non-loop`, event will occur when the card is released
nfc.on('touchend', () => {
  console.log('Card was away.');

  // Card reading will start five seconds after the card is released
  setTimeout(() => {
    nfc.start();
  }, 5000);
});

nfc.on('error', (err) => {
  // standard error output (color is red)
  console.error('\u001b[31m', err, '\u001b[0m');
});

non-touchend mode

'use strict';

const NfcpyId = require('node-nfcpy-id');
const nfc = new NfcpyId({mode: 'non-touchend'}).start();

nfc.on('touchstart', (card) => {
  console.log('Card ID: ' + card.id);
  console.log('Card Type: ' + card.type);
});

nfc.on('error', (err) => {
  // standard error output (color is red)
  console.error('\u001b[31m', err, '\u001b[0m');
});

To start (restart) reading cards, use nfc.start().

To pause reading cards, use nfc.pause().

To stop this script, press control+C. By this, Python process will be killed at the same time.

To use this script with other than SONY Pasori RC-S380, it may be necessary to modify reader.py and add options to the parameter of constructor.

const NfcpyId = require('node-nfcpy-id');

// Put the modified Python script in the same directory.
const nfc = new NfcpyId({scriptPath: __dirname, scriptFile: 'new-reader.py'}).start();

// If the file name of the modified Python script is `reader.py`, `scriptFile` can be omitted.
// const nfc = new NfcpyId({scriptPath: __dirname}).start();
