What kind of transactions can a wireless credit card terminal support?

A wireless credit card terminal is designed to facilitate a variety of payment types, which include both credit and debit transactions. These devices utilize wireless technology, such as Bluetooth or cellular signals, to process payment information securely and efficiently, allowing merchants to accept payments on the go.

The capability to support both credit and debit transactions provides merchants with the flexibility to serve a wider range of customers, as some may prefer to pay with a debit card linked to their checking account, while others may use a credit card for purchases. This versatility is essential in today's fast-paced retail environment, where convenience and customer satisfaction are paramount.

In contrast, the other options are too limited in scope, as they restrict the terminal's functionality to just one type of transaction or even cash only, which is not relevant to the capabilities of electronic payment processing through a credit card terminal.
