"Coming to Cardiff is huge for me," he told the official website.
"I didn't put in for a request to leave Birmingham, but Cardiff came in for me and when it was agreed I was really, really interested to come and play here. The ambition of this club really excites me. I want to be in the Premier League and that's where I see this club heading with everything they're putting into it.
"I'd also like to thank Birmingham City and the fans there for giving me an opportunity to get where I am as a professional footballer. I've been there since I was fifteen and made my way up through the teams, so I want to thank them, wish them all the best and to have every success for the future. The fans want and deserve success as well."
"I obviously know Malky from my time at Watford and I know how great he is as a manager," Jordon continued. "He brought me in on loads while I was there. It was a time when I grew as a player, became stronger physically and matured.
"I'm also happy to be at such a big club, a great stadium and playing for such a big fan base. I've been told about the new training ground which is to be built and I'm looking forward to what the next twelve months can bring. Hopefully we can sign some more players to make the squad bigger and from there push for promotion. I've read about the Malaysian investment in Cardiff City and I'm sure there will be more new signings."
Jordon's arrival adds to the midfield ranks, with some real quality already in place. But the competition for that starting spot for Cardiff City is one the new boy is relishing rather than fearing.
"I'm confident in my ability and can't wait to get my teeth into next season," he said. "I had a good half season with Birmingham after I was injured for the first six months, but I came back in, scored some goals and assisted more. My goal now is to play most of the games I can for Cardiff.
"I've watched Cardiff play and know what they're all about. I've played against a lot of the lads with Birmingham, Watford and when I was also on loan, coming on as a sub for Doncaster. I also know Don and Tayls from my time at Vicarage Road, and I'm familiar with how Malky likes to play.
"Hopefully we can all do well next season and get into the Premier League as that's my ambition. This club deserves to be there too, so we'll try to achieve just that."
