<sod>  Some supermarkets have introduced self-checkout machines, where the customer is trusted (to an extent) to scan the barcodes (or manually identify uncoded items like fruit), and place the items into a bagging area (where the bag is weighed, the machine complains vocally when it thinks that something in the bag doesn't seem to weigh what the inventory database lists the weight as). There is normally a supervisor watching over several such checkouts. Payment on these machines is accepted by card [[EFTPOS]], or cash via coinslot and bank note scanner.
 
 ==Origin==
The first cash register was invented by [[James Ritty]] in [[1879]]. He was the owner of a tavern in [[Dayton, Ohio]], and wanted to stop dishonest employees from pilfering his profits. He invented it after seeing a tool that counted the revolutions of the propeller on a steamship. With the help of John Birch, he patented it in 1883.  {{fact}}
