Acronym for Self Check Out. Also known as a self-serve checkout. The alternative to a manned register at a supermarket. A group of registers seen in new and refurbished supermarkets that allows customers to scan and pay for their own items, hopefully with minimal assistance from a staff member.
The staff member must press 'Go to SCO' after assisting the customer in the assistance mode so the register returns to the customer 'scan and bag' mode.
