Each user in the Mayfall system is assigned unique IDs, whether owner of the machine or guest user (such as a physician or caregiver)for safety reasons.
In the case of two users sharing a machine, each container has the option when setting up who can dispense and alter it. If Samantha has a prescription in Container B, she will set it to so only she can dispense it while Bob—the other user—cannot.
All changes and dispenses are recorded within the app.
