But Paul Ince believes it is only "50-50" whether his 21-year-old son will move for a fee reported to be £8m.
"Cardiff have come in massively for Thomas, the chairman's [Karl Oyston] accepted the offer," Ince said.
"I'm not sure what the offer is because I've been away but it's been accepted.
"So it's a case of when he comes back next week, Thomas, we'll sit down and see what he wants to do."
Blackpool have been on warm-weather training in Portugal, but Tom Ince was given extra time off because of his involvement with England Under-21s at the European Championship, and is not due back at the club until a week on Monday.
He is one of the most sought-after players in the Championship having established himself as a goal-scoring midfielder at Bloomfield Road, scoring 18 times in 49 appearances last season.
