Multiple Choice

The concept of electronic cash is to execute payment by which method?

Electronic cash refers to money that exists only in digital form and can be transferred directly between parties over a network, just like handing someone cash but in data form. The essence is that the value moves as electronic data through computers and networks, enabling immediate online payments without using physical instruments. That’s why the best choice is paying via computers over a network: it describes the transfer of digital money over a network, the core idea of electronic cash. In contrast, a credit card or ATM card relies on a card and bank networks to authorize a payment, not a direct digital transfer of cash value. A cheque is a paper-based instruction to transfer funds, not electronic cash.
