7 * TODO:
8 * - add smart card reader support for Conditional Access (CA)
9 *
10 * Card reader in Anysee is nothing more than ISO 7816 card reader.
11 * There is no hardware CAM in any Anysee device sold.
12 * In my understanding it should be implemented by making own module
13 * for ISO 7816 card reader, like dvb_ca_en50221 is implemented. This
14 * module registers serial interface that can be used to communicate
15 * with any ISO 7816 smart card.
16 *
17 * Any help according to implement serial smart card reader support
18 * is highly welcome!
