It's a small metal adapter, known as a Conditional Access Module that slides into the CI slot on a digital TV set. A CAM measures 10 x 5.5cm.
The CAM has it's own slot, into which you can slide a credit-card-sized subscription card.
I want it as I want ESPN and dont want another box under my TV!
Also if anyone has got a spare unused top up tv card with the adapter I would be ineterested.
Will pay £10 to get started (anyone want to haggle then I'm up for that!)
