<h1>Welcome to the Taler "Demo" Shop</h1>
<p>This "toy" website provides you with the ability to
experience using the
<a href="https://www.taler.net/">GNU Taler</a>
payment system without using
valuable currency. Instead, for the demonstrator we
will be using a "toy" currency, KUDOS. However, please remember that
Taler is designed to work with ordinary currencies, such
as Dollars or Euros, not just toy currencies.
<br>
This page, <tt>shop.demo.taler.net</tt> models the behavior of a
typical Web shop supporting Taler. The other pages of the demo,
<tt>mint.demo.taler.net</tt> and
<tt>bank.demo.taler.net</tt>, correspond to a Taler mint
and bank with tight Taler integration respectively.
<!-- TODO: maybe offer the wallet at 'taler.net/extension' in the
future, instead of at 'demo.taler.net/'? -->
</p>
</article>
<section id="instructions">
<article id="installation">
<h2>Step 1: Installing the Taler wallet (once)</h2>
<p>First, you need to install the Taler wallet browser extension.
It is currently only available for Firefox. If you run
Firefox, simply click <a href="http://demo.taler.net/extension">here</a>
to download and install the extension. You will then have to
click on "allow" and "install" dialogs shown by Firefox.
After that, the Taler logo should appear on the right side
of your navigation bar.
<!-- TODO: insert screenshot highlighting the icon? -->
</p>
</article>
<article id="installation-done" style="display:none;">
<h2>Step 1: Installing the Taler wallet (done!)</h2>
<p>Congratulations, you have installed the Taler wallet correctly.
You can now proceed with the next steps.
</p>
</article>
<article id="wire" style="display:none;">
<h2>Step 2: Withdraw coins (occasionally)</h2>
<p>The next step is to withdraw coins, after all you cannot
pay with an empty wallet. To be allowed to withdraw
coins from a mint, you first need to transfer currency to the mint
using the normal banking system, for example by using a
wire transfer. If the bank offers a tight integration with Taler, it
may also support this directly over the home banking online interface.
<br>
For the demonstration, we have created a "bank" that
allows you to "wire" funds (in KUDOS) to the mint simply by
filling in the desired amount into a form. Naturally, when
using a real bank with real money, you would have to authenticate
and authorize the transfer.
<br>
Note that you would not do this step for each purchase or each shop.
Payment with Taler is like paying
with cash: you withdraw currency at the bank (or an ATM) and then
pay at many merchants without having to authenticate each time.
<br>
So, unless you have already done so, please go ahead and withdraw
KUDOS at the
<a href="http://bank.demo.taler.net/" target="_blank">Demo bank</a>
(opens in a new tab).</p>
</article>
<article id="payment" style="display:none;">
<h2>Step 3: Shop! (as long as you have KUDOS left in the wallet)</h2>
<p>Now it is time to spend your hard earned KUDOS.
Note that we cannot really tell if you got any yet,
as your Taler wallet balance is visible to you, but
of course is hidden entirely from the shop.</p>
<p>The form that follows corresponds to the shopping
cart of a real Web shop; however, we kept it
very simple for the demonstration.</p>
<p>So, please choose a project and the amount of KUDOS you
wish to donate:</p>
<form name="tform" action="/checkout.php" method="POST">
<div class="participation" id="fake-shop">
<br>
<input type="radio" name="donation_receiver" value="Taler" checked="true">GNU Taler</input>
<br>
<input type="radio" name="donation_receiver" value="Tor">Tor</input>
<br>
<input type="radio" name="donation_receiver" value="GNUnet">GNUnet</input>
<br>
<select id="taler-donation" name="donation_amount">
<option value="0.1">0.1 KUDOS</option>
<option value="1.0">1 KUDOS</option>
<option value="6.0">5 KUDOS (*)</option>
<option value="10.0">10 KUDOS</option>
</select>
<input type="hidden" name="donation_currency" value="KUDOS"/>
<input type="submit" name="keyName" value="Donate!"/>
<br>
<br>
</div>
</form>
<p>(*) To make it a bit more fun, the 5 KUDOS option
is deliberately implemented with a fault: the merchant will try to
make you donate 6 KUDOS instead of the 5 KUDOS you got to see. But do
not worry, you will be given the opportunity to review the
final offer from the merchant in a window secured
by the Taler extension. That way, you can spot the
error before committing to an incorrect contract.</p>
