Which of the following is NOT a form of electronic payment?

Cash is considered a physical form of payment, as it involves the exchange of tangible currency, such as coins and paper bills, between parties. Unlike electronic payments, which utilize technology to facilitate transactions without the direct exchange of physical money, cash transactions take place in person and do not involve any electronic systems or devices.

In contrast, electronic checks, credit cards, and pay-by-phone systems all utilize technology to process payments. Electronic checks involve the digital representation of a traditional check, allowing for faster and more convenient processing through online banking. Credit cards are a widely accepted form of electronic payment, enabling consumers to make purchases and transfer funds electronically. Pay-by-phone systems allow users to complete transactions using their mobile devices, typically through apps or mobile websites, showcasing the versatility of electronic payment methods.

Thus, identifying cash as not being a form of electronic payment highlights the distinction between traditional and modern transaction methods where technology facilitates the exchange of money.
