Self-scanning checkout, also called “self-checkout” is an automated process that enables shoppers to scan, bag, and pay for their purchases without human assistance. A typical self-scanning checkout lane looks like a traditional checkout lane except that the shopper interacts with a computer’s user interface (UI) instead of with a store employee. Instructions are given to guide shoppers to complete the checkout process. Typically, the customer scan each item or manually enter its identification code and bag it. The weight observed in the bagging area is verified against previously stored information to ensure that the correct item is bagged, allowing the customer to proceed only if the observed and expected weights match. After scanning and bagging, customer may choose method of payment: debit card, credit card, or cash. There is normally an attendant watching over several self checkout machines, to provide assistance, prevent theft through exploitation of the machines’ weaknesses, and to enforce payment. Attendant assistance is also required for the purchase of age-restricted items.<\/p>\n

\nSelf checkout systems provides the benefit of reduced checkout time because stores are often able to efficiently run two to six self checkout units where it normally would have had one cashier. To some degree customers appreciate the ability to not have to deal with anyone, giving an illusion of privacy and anonymity. However this significantly reduces number of jobs available to actual employees (think terminator). Even though there are self checkout attendants around that could be reached, tracking of transactions is now land on that employee to ensure all are processed correctly. This introduces new opportunities for shoplifters to hit a merchant.<\/p>\n
\nNew interesting implementation of checkout solutions is a contactless payment using RFID system. Each items in the store will be labeled with RFID tags, and there will be RFID readers to detect the items that each shopper has in his\/her cart. When shopping is done, he\/she will not need to scan their items, but they can just walk out the store’s door, adding convenience and efficiency.<\/p>\n
\nSelf checkout systems are becoming more prevalent. Many grocery stores are having a mix of having both self checkout lanes and store associate lanes. Although these places need to be more cautious in deploying such technology, this system has a strong value and will likely to continue to evolve and add capabilities. The future for a self checkout systems is no doubt going to increase rapidly, and hopefully we’ll eventually see stores with 100 percent self checkout system.<\/p>\n
