The Republic of Ireland international is due to complete a move in the coming days, following a three-year spell with the recently relegated club.
26-year old Pilkington, who frequently plays out wide in an attacking capacity, scored 15 goals during his spell at Carrow Road, and BBC Sport are reporting that Bluebirds boss Ole Gunnar Solskjaer is looking to strengthen out wide, with Craig Noone restricted to the sidelines until September.
The six-time capped international previously played for Stockport County and Huddersfield Town, as well as turning out for the youth teams of both Manchester United and Blackburn Rovers.
He struggled to nail down a first-team role at Carrow Road last season - making just 15 Premier League appearances - and it appears as if the time was right to move away from Norwich.
And, having swapped one relegated team for another, Pilkington will be hoping he can play an important part in Cardiff's search for an immediate return to top flight football.
He offers further creativity to a Cardiff midfield packed with talent, and is sure to register a number of assists throughout the course of the season - whilst also chipping in with his fair share of goals. Whilst his goalscoring record is not enough to single-handedly lead a team to victory, he can find the back of the net enough times to contribute to a long and gruelling Championship campaign.
The winger will be the eighth arrival to Wales this summer, whilst head coach Solskjaer has also revealed he is still on the look out for central defensive replacements, having lost Steven Caulker to QPR, and Ben Turner and Juan Cala to injury and suspension respectively. Reading's Sean Morrison and Watford's Joel Ekstrand have been mentioned as prospective replacements, although both seem unlikely with their current clubs harbouring promotion aspirations of their own.
