+      </h3>
+      <p>We want to improve the user experience in a variety of ways. These include reducing the need to provide data as part of
+        a transaction (helpful on mobile in particular), simplifying payment user interfaces and interactions, standardizing the
+        payment flow across all Web applications, and making it easier to make payments from a wide range of devices, such as computers,
+        portable devices, televisions, eBooks, and automobiles.</p>
+      <p>Taken together, we expect these improvements will lower the rate of "cart abandonment" and increase the velocity of payments
+        made over the Web.</p>

+      </h3>
+      <p>Trust in Web payments is critical to their widespread adoption. Because of this the architecture must provide the ability
+        for participants in the payment process to confidently, securely and accurately identify and connect to other participants
+        that are party to the payment.</p>
+      <p>The architecture should not disclose private details of the participants identity or other sensitive information as part
+        of the payment process unless required by operational, legal or jurisdictional rules, or when deliberately consented to (e.g.
+        as part of a loyalty program) by the owner of the information.</p>
+      <p>The Web payments architecture should make this easy by standardizing the mechanisms available to issue, exchange and verify
+        credentials as part of a payment transaction, as well as a secure mechanism for the exchange of identity information when
+        it is explicitly required as part of a payment. To accomplish this, it is expected that the architecture will also need to
+        support an evolving variety of authentication and identification techniques (e.g. multifactor, biometric, etc.) which can
+        be used independent of or in concert with a participants identity data.</p>

+        <li>
+          <strong>Minimalist</strong>, in order to accommodate diverse existing and emerging schemes.</li>
+        <li>
+          <strong>Extensible</strong>, so that above and beyond the minimum information required for interoperability, parties involved in
+          payments can exchange the information they require, using the formats and protocols they prefer.</li>

+      </h3>
+      <p>Different payment schemes move value at different speeds. The Web payments architecture should not impose additional delays,
+        so that payment information circulates as efficiently as possible and the final settlement (exchange of value) is done as
+        quickly as possible.</p>

+      </h3>
+      <p>The Web is a global system which must operate across many legal and regulatory jurisdictions. While there are common requirements
+        across jurisdictions, it is not cost-effective to create a single system that satisfies all legal and regulatory obligations
+        in all jurisdictions.</p>
+      <p>As a result, a successful architecture for payments on the web will account for variability with regard to legal and regulatory
+        frameworks it can support. The group envisions an extensible set of 'hooks' that enable participant-authorized parties to
+        comply with legal and regulatory requirements in different jurisdictions in a secure and more standard manner.</p>
+      <p>We believe the industry will benefit from standards that lower the cost (e.g. through automation) of addressing needs related
+        to Know Your Customer, Anti-Money Laundering, and other requirements related to due diligence and customer identity.</p>
