When it comes to conveying items directly from one person to another, there are a variety of ways to describe this type of transfer without using the phrase "hand to hand deliveries." For example, you might describe it as a "personal exchange," a "direct transfer," or a "direct handoff." Alternatively, you could refer to it as a "face-to-face transaction," a "one-on-one delivery," or a "individual handover." Other possible synonyms include "manual handover," "direct delivery," "person-to-person exchange," or "physical transfer." Regardless of the phrase you choose, the idea remains the same: a direct, human-to-human transfer of goods or information.
