Mommy make over
Thank you for your question. I believe that you will be able to use your husband's Care Credit account as long as you have authorization. I would call Care Credit to double check and maybe have your husband send an email authorizing you to do so. Best Wishes.
Even with autherization from your husband, it is not appropriate or acceptable to use your husband's card, since he is out of the country and is unable to sign for the charges. He can contest the charges since he did not sign for it
