Automation of service industries includes an assortment of applications as diverse as the services themselves, which include health care, banking and other financial services, government, and retail trade.

In health care the use of automation in the form of computer systems has increased dramatically to improve services and relieve the burden on medical staffs. In hospitals computer terminals on each nursing care floor record data on patient status, medications administered, and other relevant information. Some of these systems are used to perform additional functions such as ordering drugs from the hospital pharmacy and calling for orderlies. The system provides an official record of the nursing care given to patients and is used by the nursing staff to give a report at shift-change time. The computer system is connected to the hospital's business office so that proper charges can be made to each patient's account for services rendered and medicines provided.

Robotics is likely to play a role in future health care delivery systems. The work that is done in hospitals by nurses, orderlies, and similar staff personnel includes some tasks that are routine and repetitive. Duties that might be automated using robots include making beds, delivering linens, and moving supplies between locations in the hospital. Robots might even become involved in certain aspects of patient care such as transporting patients to services in the hospital, passing food trays, and similar functions in which it is not critical that a hospital staff member be present. Research is currently under way to develop robots that would be capable of providing assistance to paraplegics and other physically handicapped persons. These robots would respond to voice commands and would be able to interpret statements in natural language (e.g., everyday English) from patients requesting service.

Banking and financial institutions have embraced automation in their operations—principally through computer technology—to facilitate the processing of large volumes of documents and financial transactions. The sorting of checks is done by optical character-recognition systems utilizing the special alphanumeric characters at the bottom of checks. Bank balances are computed and recorded using computer systems installed by virtually all financial institutions. Major banks have established electronic banking systems, including automatic teller machines. Located in places convenient for their customers, these automatic tellers permit users to complete basic transactions without requiring the assistance of bank personnel.

The stock exchanges rely on computer-automated systems to report transactions by ticker tape or closed circuit television. Brokerage houses use a computerized record-keeping system to track their customers' accounts. Monthly statements indicating the status of each account are automatically prepared and mailed to customers. Account executives employ video monitors in their offices, backed by a massive database, to retrieve current information on each stock almost instantaneously while they discuss possible purchases with their clients. Stock certificates are typically issued with machine-readable identifications to facilitate record keeping in sales and exchanges.

Credit card transactions have also become highly automated. Restaurants, retailers, and other organizations are using systems that automatically check the validity of a credit card and the credit standing of the cardholder in a matter of seconds as the customer waits for the transaction to be finalized. Some credit card transactions trigger immediate transfer of funds equal to the amount of the sale from the cardholder's account into the merchant's account.

Many government services are automated by means of computers and computerized databases. The Internal Revenue Service (IRS) of the U.S. government must review and approve the tax returns of millions of taxpayers each year. The detailed checking of returns is a task that has traditionally been done by large staffs of professional auditors on a sampled basis. In 1985 the IRS began using a computerized system to automate the auditing procedure for the 1984 returns. This system is programmed to perform the complex tax calculations on each return being audited. As tax laws change, the system is reprogrammed to do the calculations for the year. The computerized auditing system has permitted a substantial increase in the work load of the IRS auditing department without a corresponding increase in staffing.

Retail trade has seen a number of changes in its operations as a result of automation. Selling merchandise has typically been a very labour-intensive activity, with sales associates needed to assist customers with their selections and then finalize transactions at the cash register. Each transaction depletes the store's inventory, so the item purchased must be identified for reorder. Much clerical effort is expended by the store when inventory is managed by strictly manual procedures. Computerized systems have been installed in most modern retail stores to speed sales transactions and automatically update inventory records as the stock of each item is reduced. The systems are based on the Universal Product Code (UPC), originally adopted by the grocery industry in 1973, which uses optical bar-code technology. A bar code is an identification symbol consisting of a series of wide and narrow bars attached to each product that can be scanned and recognized by a bar-code reader. At the cash registers, these readers quickly identify the items being purchased. As the sales associate scans across the symbol using a laser beam reader, the product is properly identified and its price is entered into the sales transaction. Simultaneously, a record of the sale is made in the inventory files so that the item can be reordered.
