How to give NMT in ACNH?

I'm curious, how exactly does one go about giving NMT, or Nook Miles Tickets, in Animal Crossing: New Horizons? I've heard they're a valuable currency that can be used to purchase special items from the Nook Stop, but I'm not sure how to actually transfer them to another player. Is there a specific process I need to follow, or is it as simple as dropping them on the ground? I'd appreciate any clarity you can provide on this matter.
