What is a wireless terminal primarily used for?

A wireless terminal is primarily used for processing transactions through a cellular data network. This technology enables merchants to accept payments from customers without the need for a physical connection to a wired network, making it particularly useful in mobile transactions, on-the-go sales, or situations where internet connectivity is limited. The versatility of wireless terminals allows them to function independently of traditional point-of-sale systems, which often rely on fixed-line connections.

The other options, while they highlight some aspects of devices used for transactions, do not accurately define the primary purpose of a wireless terminal. For instance, connecting to Wi-Fi is beneficial for certain transaction types but does not encompass the full scope of what a wireless terminal can do, particularly its reliance on cellular data for communication. Additionally, restricting functionality to only credit cards does not accurately reflect the capabilities of wireless terminals, as they can also process debit card transactions and various forms of mobile payment. Lastly, the notion that a device is solely powered by electricity is misleading, as many wireless terminals are designed with battery capabilities specifically to support their mobile functionality.
