16 * TODO:
17 * - add smart card reader support for Conditional Access (CA)
18 *
19 * Card reader in Anysee is nothing more than ISO 7816 card reader.
20 * There is no hardware CAM in any Anysee device sold.
21 * In my understanding it should be implemented by making own module
22 * for ISO 7816 card reader, like dvb_ca_en50221 is implemented. This
23 * module registers serial interface that can be used to communicate
24 * with any ISO 7816 smart card.
25 *
26 * Any help according to implement serial smart card reader support
27 * is highly welcome!
