Point-of-Sale Devices
Point-of-sale (POS) devices are terminals used in retail operations to enter sales
information into the computer system. The POS device then computes the total charges,
including tax.
Many POS devices also use other types of input and output devices, such as keyboards,
barcode readers, printers, and screens. Much of the money that businesses spend on
computer technology involves POS devices. First Data, Hewlett-Packard, and Microsoft have
collaborated to create a combined hardware and software point-of-sale solution for small
retailers called First Data POS Value Exchange. The system can handle all forms of
payment including cash, check, credit, debit, and gift cards. The software comes installed on
Hewlett-Packard’s rp5000 computer, complete with a touch screen interface.

Question 2
, Which of the following types of processing is essential for businesses that require access to
current data such as airlines, ticket agencies, and stock investment firms?
1. Batch processing
2. Multiple unit processing
3. Business intelligence processing
4. Online transaction processing
With online transaction processing (OLTP), each transaction is processed immediately,
without the delay of accumulating transactions into a batch (see Figure 9.2b). Consequently,
at any time, the data in an online system reflects the current status. This type of processing
is essential for businesses that require access to current data such as airlines, ticket
agencies, and stock investment firms. Many companies find that OLTP helps them provide
faster, more efficient service—one way to add value to their activities in the eyes of the
customer. Increasingly, companies are using the Internet to capture and process transaction
data such as customer orders and shipping information from e-commerce applications.
