Working with eastern technique allows for minimal contact (3-5)

'for minimal contact' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'working with eastern technique' is the wordplay.
'working' becomes 'on' (on can mean working or activated).
'with' is a charade indicator (letters next to each other).
'eastern' becomes 'e'.
'technique' becomes 'touch' (I can't explain this - if you can you should believe this answer much more).
'on'+'e'+'touch'='ONE-TOUCH'

'allows' is the link.

Can you help me to learn more?
