Self-checkout machine
Self-checkouts, are machines that provide a mechanism for customers to complete their own transaction from a retailer without needing a traditional staffed checkout. When using SCOs, customers scan item barcodes before paying for their total shop without needing one-to-one staff assistance. Self-checkouts are used mainly in supermarkets, although they aren't uncommon in department or convenience stores. As of 2013, there were 191,000 self-checkout units deployed across the globe, and by 2025, it is predicted that 1.2 million units will be installed worldwide.
