NFC Tags have the advantage that you can easily read them using a cheap phone and write them by yourself with a free application (Android, iOS, BlackBerry or Windows). NFC Tag has an Unique Identification Number (UID), separeted from its memory, so NFC Tags can be used also for access control, tracking or for certificate the authenticity of a product.
