I have cancled my direct tv account 4 months ago Now I have 2 direct recievers with cards the cards with them are a access card that is light blue and a card that has silver on the top and bottom with direct tv written in the middle. Is there anything i can do with these cards. I also have a dishnetwork card and reciever when looking on the back of that card i see NagraVision Swiss Mode. I am just wondering if there is anything that i can do to these cards inorder to get service free. Or do i just use them as throwing stars.
