<section id="abstract">
  <p>
    This document provides a collection of use cases and usage scenarios for
    web pages and applications using Near Field Communication (NFC).
    More information about Web NFC can be found
    <a href="http://w3c.github.io/web-nfc/index.html#abstract">here</a>.
  </p>
  <p>
    This specification defines an API to manage selected NFC use-cases from Web
    applications and pages, and to enable new use-cases based on NFC technology.
  </p>

  <p>
    This document provides informative background to the
    <a href="http://w3c.github.io/web-nfc/index.html">Web NFC specification</a>.
    Comments on the document should be filed as issues at
    <a href="https://github.com/w3c/web-nfc/issues">
    https://github.com/w3c/web-nfc/issues</a>.
  </p>
</section>

<section> <h2>Terminology</h2>
  <p>
    For NFC terminology see the
    <a href="http://w3c.github.io/web-nfc/index.html#terminology">
    Web NFC specification</a>.
  </p>
</section>

<section class="informative"> <h2>Use Cases</h2>
  <p>
    A few NFC user scenarios have been enumerated
    <a href="http://www.w3.org/2009/dap/wiki/Near_field_communications_%28NFC%29#Use_cases_submitted_to_DAP_mailing_list">
    here</a>. For the Web NFC API in particular, a few examples of intended
    user scenarios follow next.
  </p>
  <section> <h3>Reading generic information in a museum</h3>
    <p>
      The user touches an NFC capable device to information points of works of
      arts in a museum, obtaining information about the exposed items. Also,
      by touching information points in halls, the user can get suggested
      itineraries, schedule and other information to the personal device for
      later consultation.
    </p>
  </section>
  <section> <h3>Reading information in administration office</h3>
    <p>
      In a population administration office, the user touches in information
      point in order to save a list of documents required for renewing a
      passport, and obtaining a the next queuing number for the clerk.
    </p>
  </section>
  <section> <h3>Updating tag information</h3>
    <p>
      A museum employee touches information points with a special device which
      can write to the museum's NFC tags in order to update (read, then write)
      information on them.
    </p>
  </section>
  <section> <h3>Sending image to another Web NFC capable device</h3>
    <p>
      While a user is actively interacting with web site, e.g.
      https://images.example.com/, and if the user taps the device with
      another device where another user is actively interacting with the
      same web site https://images.example.com/, then they can initiate
      sending an image from one device to the other, using the NFC
      connection or by handover to Bluetooth or WiFi connection.
      The second device may be for instance a TV set to show the picture,
      or a personal computer for image processing.
    </p>
  </section>
  <section><h3>Handover to Bluetooth</h3>
    <p>
      NFC supports handover protocols to Bluetooth or WiFi connectivity for
      the purpose of larger volume data transfer. The user touches another
      NFC capable device, and as a result configuration data is sent for a
      new Bluetooth or WiFi connection, which is then established between the
      devices.
    </p>
    <p>
     A related use case for gaming has been described
     <a href=":https://webbluetoothcg.github.io/web-bluetooth/use-cases.html">
     here</a>.
     Other use cases may include bulk transfer of contacts cards, photos,
     and other data.
    </p>
  </section>
  <!--
  <section> <h3>Payment to another user</h3>
    <p>
      The user navigates to a web site which manages seller and buyer accounts
      and touches the device to another device of another user. A payment can
      be made between the two users' accounts.
    </p>
  </section>
  <section> <h3>Payment for services</h3>
    <p>
      On an automated point of sales terminal, such as ticketing machines,
      the user navigates to a web site which offers the paid service.
      By touching the receiver area of the point of sales, the payment can be
      done and the ticket can be delivered electronically to the user's
      device.
