Cash transactions remain a key element of POS systems, especially in physical retail environments. In e-commerce, cash is less common but can still be involved in certain models like Cash on Delivery (COD).
Digital wallets (like Apple Pay, Google Pay, PayPal, etc.) are integrated into POS systems to allow customers to complete transactions without using physical cards or cash.
Bank Transfers and Credit Cards are crucial components of POS systems, particularly in both physical retail and e-commerce environments.
