abstract:In biology or medicine, a multi-access key is an identification key which overcomes the problem of the more traditional single-access keys (dichotomous or polytomous identification keys) of requiring a fixed sequence of identification steps. A multi-access key enables the user to freely choose the set and characteristics that are convenient to evaluate for the item to be identified.
Always-on, device-independent, multi-channel, anytime-anywhere access to business information and transactional capabilities is rapidly becoming the key differentiator for both customer and user experience.
