+==== Icc Object Life Cycle ====
+Icc object only be created when corresponding icc is detected by system. And becomes invalid after the it can not be detected by system any more.
+* You can use IccManager to monitor this.
+    var iccManager = navigator.mozIccManager;
+    iccManager.oniccdetected = function (evt) {
+        var iccId = evt.iccId;
+        // A new icc is detected by device.
+        // You can use this iccId to get icc object from iccManager.
+    }
+    iccManager.oniccundetected = function (evt) {
+        var iccId = evt.iccId;
+        // An icc becomes undetected.
+    }
+* If you already hold a reference for a specific icc object, you still can know this via it's cardState or iccInfo.
+    var icc = iccManager.getIccById(iccId);
+    icc.oncardstatechange = function () {
+       if (icc.cardState === null) {
