Systems and methods for emulating credentials. In some cases, the systems include an access control module with an access credential reader that is operable to receive an access information from one access credential, and an access credential writer that is operable to provide at least a portion of the access information to another access credential. The written access credential is operable to receive the portion of the access information from the access credential writer. Upon receiving the information, the written access credential becomes operable to access an access point. Some systems and methods are related to access control, while other systems and methods are related to payment, access, and/or other transaction devices used in relation to credentials.
