Expression: self-service and Word: cashier

Hello,

Which one is correct: self-service cashier, self-servicing cashier or self-cashier?

Many thanks in advance.

Thank you for your explanation.

I was referring to the machine though. I actually used a cashier that I scanned all my shopping items and did the paying like when we use a vending machine.

What should I call that thing?

I think we'd call that a self-serve scanner. The process is called self-serve checkout. Various stores have their own names for it.

Many thanks!
