<prompt> Human: My only CC debt is on a single card, roughly 3500 with Barclay 15,000 limit. Im looking to do a balance transfer to the Chase Slate card 0 transfer fee and 0 for 15 months, I pay 300 a month on it currently and that would have it paid off within the 15 month windowIve read that adding your kids to your cards as authorized users can help build their credit. My kids are 9 and 6 currently. Chase doesnt appear to have a minimum age requirement, and obviously I wouldnt give them the cards. I realize should something go wrong with our finances doing this could damage their credit as well. Is there any other things to consider before doing this?  <response>: I see no reason to do this now: There is no reason for a 9 year old to have a credit report. The things you do now will not be relevant to their credit in 9 years when your oldest turns 18.Maybe reconsider when they are 15 or 16.
