PN532.js

PN532.js is a JavaScript library for PN532 base on Web Bluetooth and Web Serial.

API Reference | Example

Browser & OS compatibility

SerialPort (Node.js)

Node SerialPort is a JavaScript library for connecting to serial ports that works in NodeJS and Electron.

Web Bluetooth API

A subset of the Web Bluetooth API is available in ChromeOS, Chrome for Android 6.0, Mac (Chrome 56) and Windows 10 (Chrome 70). See MDN's Browser compatibility table for more information.

For Linux and earlier versions of Windows, enable the #experimental-web-platform-features flag in about://flags.

Web Serial API

The Web Serial API is available on all desktop platforms (ChromeOS, Linux, macOS, and Windows) in Chrome 89. See MDN's Browser compatibility table for more information.

Web Serial API Polyfill

On Android, support for USB-based serial ports is possible using the WebUSB API and the Serial API polyfill. This polyfill is limited to hardware and platforms where the device is accessible via the WebUSB API because it has not been claimed by a built-in device driver.

Prepare PN532 hardware

PN532.js support Web Serial and Web Bluetooth. You can connect PN532 to PC via an USB2TTL module (e.g. CH340, PL2303) or via BLE UART module (e.g. JDY-33, HC-08).

See Mtools Tec's How to make PN532 work on Bluetooth and How To Test PN532 Working With Bluetooth Module? for more information.

Installing

Package manager

Using npm:

$ npm install pn532.js

# Also install SerialPort if you want to run in node.js
$ npm install serialport

Using yarn:

$ yarn add pn532.js

# Also install SerialPort if you want to run in node.js
$ yarn add serialport

Once the package is installed, you can import the library using import or require:

// import
import { Pn532, Packet, utils: Pn532utils } from 'pn532.js'
import Crypto1 from 'pn532.js/Crypto1.js'
import LoggerRxTx from 'pn532.js/plugin/LoggerRxTx.js'
import Pn532Hf14a from 'pn532.js/plugin/Hf14a.js'
import Pn532SerialPortAdapter from 'pn532.js/plugin/SerialPortAdapter.js'
import Pn532WebbleAdapter from 'pn532.js/plugin/WebbleAdapter.js'
import Pn532WebserialAdapter from 'pn532.js/plugin/WebserialAdapter.js'

// require
const { Pn532, Packet, utils: Pn532utils } = require('pn532.js')
const Crypto1 = require('pn532.js/Crypto1.js')
const LoggerRxTx = require('pn532.js/plugin/LoggerRxTx.js')
const Pn532Hf14a = require('pn532.js/plugin/Hf14a.js')
const Pn532SerialPortAdapter = require('pn532.js/plugin/SerialPortAdapter.js')
const Pn532WebbleAdapter = require('pn532.js/plugin/WebbleAdapter.js')
const Pn532WebserialAdapter = require('pn532.js/plugin/WebserialAdapter.js')

After the script tag, you can use the PN532.js as following:

// setup
const {
  _, // lodash: https://cdn.jsdelivr.net/npm/lodash@4/lodash.min.js
  Pn532: { Pn532, Packet, utils: Pn532utils },
  Crypto1,
  Pn532Hf14a,
  Pn532LoggerRxTx,
  Pn532WebbleAdapter,
  Pn532WebserialAdapter,
} = window

Getting Started

use Adapter

A pn532 instance must register exactly one adapter plugin:

// setup
const {
  _, // lodash: https://cdn.jsdelivr.net/npm/lodash@4/lodash.min.js
  Pn532: { Pn532, Packet, utils: Pn532utils },
  Crypto1,
  Pn532Hf14a,
  Pn532WebbleAdapter,
  Pn532WebserialAdapter,
} = window

// Pn532WebserialAdapter
const pn532usb = new Pn532()
pn532usb.use(new Pn532WebserialAdapter()) // A pn532 instance must register exactly one adapter plugin
console.log(JSON.stringify(await pn532usb.getFirmwareVersion())) // {"firmware":"1.6","ic":"PN532","iso14443a":true,"iso14443b":true,"iso18092":true}

// Pn532WebbleAdapter
const pn532ble = new Pn532()
pn532ble.use(new Pn532WebbleAdapter()) // A pn532 instance must register exactly one adapter plugin
console.log(JSON.stringify(await pn532ble.getFirmwareVersion())) // {"firmware":"1.6","ic":"PN532","iso14443a":true,"iso14443b":true,"iso18092":true}

// Pn532SerialPortAdapter
import Pn532SerialPortAdapter from 'pn532.js/plugin/SerialPortAdapter.js'
// Run serialport-list to list port, see https://serialport.io/docs/bin-list
const pn532node = new Pn532()
pn532node.use(new Pn532SerialPortAdapter(), { path: '/dev/tty.usbserial-120' })
console.log(JSON.stringify(await pn532node.getFirmwareVersion())) // {"firmware":"1.6","ic":"PN532","iso14443a":true,"iso14443b":true,"iso18092":true}

Read UID, ATQA, SAK from Mifare Classic 1k

// setup
const {
  _, // lodash: https://cdn.jsdelivr.net/npm/lodash@4/lodash.min.js
  Pn532: { Pn532, Packet, utils: Pn532utils },
  Pn532Hf14a,
  Pn532WebserialAdapter,
} = window

const pn532 = new Pn532()
pn532.use(new Pn532WebserialAdapter()) // A pn532 instance must register exactly one adapter plugin
pn532.use(new Pn532Hf14a())
console.log(JSON.stringify(await pn532.$hf14a.mfSelectCard())) // {"pack":"Packet(9): 010004080407460D6D","atqa":"Packet(2): 0004","sak":"Packet(1): 08","uid":"Packet(4): 07460D6D","rats":"Packet(0)"}
