Store-and-forward:
Store-and-forward has some advantages over Live video since it is not in real time. The information provided by the physician is pre-recorded, stored, and accessed by the patients when required. Therefore, unlike live video which is synchronous, store-and-forward provides flexibility of time since it is asynchronous. Health data like lab tests, x-rays, and videos can be stored and shared using store-and-forward. Information can also be accessed and shared with more than one person and also used for purposes of education and awareness among people.
