What is difference cod and vpos?

COD (Cash on Delivery) is a payment method where customers pay for their goods at the time of delivery, typically in cash. VPOS (Virtual Point of Sale) is an online payment gateway that allows businesses to process credit and debit card transactions over the internet. The key difference lies in the payment timing and method: COD involves cash transactions at delivery, while VPOS facilitates electronic payments in real-time online.
