According to ABI Research, cardless conditional access systems in cable networks are expected to grow 300% in five years, from 5 million units in 2012 to 21.5 million in 2017."Cisco (NDS) has shipped the most units of cardless security to Cablevision based on its K-LAD system," said Sam Rosen, practice director at ABI. "However, Nagra and Irdeto are leading this wave of shipments in low ARPU regions, while Verimatrix's cardless technology is robust and gaining market attention."
