Start up:

  1. Connect Arduino 2560/UNO with NFC Tag
  2. Make this library to arduino IDE
  3. Use example to write Tag
  4. Use NFC Reader read it

Easy use with NDEF

You can write a NDEF message, like this:

NdefRecord records[1];
records[0].createUri("https://github.com");

Or more than one:

NdefRecord records[2];
records[0].createUri("https://github.com");
records[1].createUri("https://github.com/awong1900/RF430CL330H_Shield");

You can write data in different formats for example, URI, External, MIME, Text, even Application what can open app directly.
