touchlessness
Absence of touch
Touchlessness is the quality or state of operating without physical contact.
The word gained currency with technology that eliminates touching: touchless faucets, touchless payment systems, touchless car washes.
During disease outbreaks, touchlessness becomes a public health goal—minimizing surface contact to reduce transmission.
