    <p>Retrieves the card record count from an access controller.</p>

        <dt>payload<span class="property-type">object</span></dt>
        <dd>JSON object with the controller ID for 'get-cards'</dd>

        <dd>identifying message topic for output</dd>
    </dl>

    <h3>Outputs</h3>
    <dl class="message-properties">
        <dt>payload<span class="property-type">object</span></dt>
        <dd>JSON object with the controller card list record count</dd>
        <dt>topic<span class="property-type">string</span></dt>
        <dd>message topic copied from input</dd>
    </dl>

    <h3>Details</h3>
    <p>The input <code>msg.payload</code> is a JSON object identifying the destination controller.</p>
    <p>The controller is identified by specifying either the (legacy) 'deviceId' or the composite
    'controller' object which supports both UDP and TCP connections. Defaults to broadcast UDP if
    the address or protocol are not valid.</p>
    <dl class="message-properties">
        <dt>deviceId<span class="property-type">uint32</span></dt>
        <dd>controller serial number</dd>
        <dt>controller.id<span class="property-type">uint32</span></dt>
        <dd>controller serial number</dd>
        <dt>controller.address<span class="property-type">string</span></dt>
        <dd>controller IPv4 address</dd>
        <dt>controller.protocol<span class="property-type">string</span></dt>
        <dd>controller connection protocol ('udp' or 'tcp')</dd>
    </dl>
    <h4>Example:</h4>
    <pre>
  {
    "deviceId": 405419896
  }</pre>
    <pre>
  {
    "controller": {
        "controller": 405419896,
        "address": "192.168.1.100",
        "protocol": "tcp"
    }
  }</pre>

    <p>The output <code>msg.payload</code> is a JSON object containing the card
    record count retrieved from the UHPPOTE controller with serial number 
    matching the request:</p>
    <dl class="message-properties">
        <dt>deviceId<span class="property-type">uint32</span></dt>
        <dd>controller serial number</dd>
        <dt>records<span class="property-type">uint32</span></dt>
        <dd>count of cards stored in controller</d>
    </dl>
    <h4>Example:</h4>
    <pre>
  {
    "deviceId": 405419896,
    "cards": 397
  }</pre>
