<h3>Smart Keyless system</h3>
</section>
<section>
<h3>Components of the system</h3>
<p>
The Smart Keyless system is essentially composed of:
<ul>
<li>locker device</li>
<li>users smart phone</li>
<li>backend of the system</li>
</ul>
</p>
</section>
<section>
<h6>Architecture of the System</h6>

<h3>Data Model</h3>
</section>
<section>
<h3>Initial Data Model</h3>
<p>
Fundamental Entities of the system :
<ul>
<li>Device</li>
<li>Permission</li>
<li>User</li>
<li>Account</li>
</ul>
</p>
</section>
<section>
<h3>Questions still missing a proper answer</h3>
Open questions:
<ul>
<li>what are the possible types of account a user can have?</li>
<li>do we handle account type as different entity?</li>
<li>do we store Data onchain or offchain?</li>
<li>what are the format of msg to use?</li>
</ul>
</section>
<section>
<h3> APIs specification</h3>
<p>
Queries & function the system must support:
<ol>
<li>get list of permission for a particular locker</li>
<li>get list of active permission/token for an accessor</li>
<li>post a permission for an account</li>
<li>add a new account</li>
<li>add a new locker</li>
<li>...</li>
