Electronic payment systems allow for paperless monetary transactions through various modes like credit cards, debit cards, smart cards, and electronic funds transfers. Credit cards involve a bank paying on behalf of the customer who then has a period to pay the bill. Debit cards immediately deduct funds from the linked bank account. Smart cards contain a microchip to store customer information and funds that are deducted with use. Electronic funds transfers allow money to be transferred between bank accounts without a middleman through ATMs or online banking. E-cheques enable creating and sending checks electronically through bank-provided software. Overall, electronic payment systems have streamlined business processes by reducing paperwork, transaction costs, and processing time.
