NDEF Mifare Classic

This module reads and writes NDEF bytes to Mifare Classic NFC tags. The module is a wrapper around libfreefare command line tools.

API

mifare.read(callback)

• callback - function

Example

mifare.read(function (err, data, uid) {
  if (err) throw err;
  console.log('The NFC tag UID is', uid);

});

The callback is passed two arguments (err, data), where data is the contents of the file
