touchlessly
Not making contact
In a manner that requires no physical contact.
The term appears most often in descriptions of technology—payments, sensors, or controls that operate without touching: The door opened touchlessly as she approached.
It extends to any action performed without direct contact: He managed the situation touchlessly, delegating everything.
