<prompt> Human: We are looking into getting a credit card for my wife because although she is extremely fiscally responsible, she has no credit history from not ever owning a credit card she has always just used her bank debit card. She was unsurprisingly denied an REI card because of no credit history. Since I have good credit, would it be helpful to open a joint account? Would she still build the same credit even if she is part of a joint account? Side note: We had our eye on the REI card because it includes a 100 gift card, 5 back at REI, and 1 anywhere else. Good deal!Assistant: As long as it shows up on her credit history, then yes, it will be very helpful. Human: I suppose that is the question I am asking: Will it will show up on her credit history? Or does it depend on the card?  <response>: If her name is on the application then it will show up for sure. If she is just added as an authorized user then probably not. I have added my cats as authorized users in the past just for fun.
