{{Main|Self-checkout}}
Some corporations and [[supermarket]]s have introduced self-checkout machines, where the customer is trusted to scan the [[barcode]]s (or manually identify uncoded items like fruit), and place the items into a bagging area.<ref>{{cite web |url= http://www-03.ibm.com/products/retail/products/self/sco/index.html |archive-url= https://web.archive.org/web/20081216093720/http://www-03.ibm.com/products/retail/products/self/sco/index.html |url-status= dead |archive-date= December 16, 2008 |title= IBM Self Checkout Systems |publisher= [[IBM]]}}</ref> The bag is weighed, and the machine halts the checkout when the weight of something in the bag does not match the weight in the inventory database. Normally, an employee is watching over several such checkouts to prevent theft or exploitation of the machines' weaknesses (for example, intentional misidentification of expensive produce or dry goods). Payment on these machines is accepted by [[debit card]]/[[credit card]], or cash via coin slot and [[Bill validator|bank note scanner]]. Store employees are also needed to authorize "age-restricted" purchases, such as alcohol, solvents or knives, which can either be done remotely by the employee observing the self-checkout, or by means of a "store login" which the operator has to enter.{{citation needed|date=October 2024}}
