+        <p lang="en">Merchants supporting the Taler system need to integrate
+          some relatively simple logic into their transaction processing
+          system.
+          Typical steps performed by the merchant system are:

+          <ol>
+            <li lang="en">The new logic detects when a customer's system
+              supports Taler and then needs to send a digitally signed
+              version of the proposed contract in a simple JSON format to
+              the customer.
+              The message also includes salted, hashed wire details for
+              the merchant, as well as restrictions as to which mint operators
+              the merchant is willing to deal with.</li>

+             <li lang="it" note="outdated"></li>
+            <li lang="en">The customer sends a signed response which states
+               that certain digital coins now belong to the merchant to both
+               signal acceptance of the deal as well as to pay the respective
+               amount (bottom).</li>

+             <li lang="fr" note="outdated"></li>
+             <li lang="it" note="outdated"></li>
+             <li lang="en">The merchant then forwards the signed messages
+               received from the customer to the mint, together with its
+               wire details and the salt (without hashing).  The mint verifies
+               the details and sends a signed confirmation (or an error
+               message) to the merchant.  The merchant checks that the
+               mint's signature is valid, sends a confirmation to the
+               customer and executes the contract-specific business logic.</li>

+             <li lang="en">The mint performs wire transfers corresponding to
+               the claims deposited by the merchant.  Note that the mint may
+               charge fees for the deposit operation, hence merchants may
+               impose limits restricting the set of mint operators they are
+               willing to deal with.</li>
