Unfortunately, there is no possibility to use your Kay Jewelers credit card at other stores. It is a store credit card that is not affiliated with any major payment network. So it can only be used at Kay Jewelers stores. If you want to have a credit card that is accepted everywhere, you should apply for a general credit card with rewards. For example, consider cash back credit cards. Earned cash back can be used for your future purchases.
