Starting the graveyard shift, nurse Joe takes over his colleague’s shift, making his way to his first patient of the night. When he reaches for the sleeping, bedridden individual, he silently scans the ID bracelet. Having mobile access to the patient’s records, he sees Mrs. Johnson’s allergies and knows that she’ll have to be awaken in another hour to take her medication. Through his scan, Joe also sees the results to Mrs. Johnson’s blood test are available, which he can share with her when she wakes.

Having scanned the empty prescription bottle on the side of the bed, Joe is also able to determine how many more refills Mrs. Johnson has.
