+ *
+ * Card reader in Anysee is nothing more than ISO 7816 card reader.
+ * There is no hardware CAM in any Anysee device sold.
+ * In my understanding it should be implemented by making own module

+ * module registers serial interface that can be used to communicate
+ * with any ISO 7816 smart card.
+ *

+ * is highly welcome!
