Identifies the Person who picked up (i.e., took custody of) the dispensed medication, if that person is someone other than the patient. Note that this class points to the Person picking up the medication, and that the Person class contains the name, address, and identification of that individual. Note also that the Person Id property uses the Id data type, which can be used for any kind of identification that the Pharmacy accepts. Therefore, the Id can accommodate the use of a Personal Identification Verification (PIV) card or a Common Access Card (CAC) or any other kind of identification accepted by the Pharmacy. The Id datatype also includes an Id Type field, which indicates whether the Id was a driver’s license, a passport, a PIV or CAC card, etc. "Identifies the person who picked up the medication. This will usually be a patient or their caregiver, but some cases exist where it can be a healthcare professional." - HL7 FHIR, MedicationDispense.receiver
