McDonald's Singapore's customers who are Visa card holders can now pay for orders delivered to their doorstep through a mobile application.

The fast-food giant's Singapore unit launched the payment system - its first in South-east Asia - in partnership with the credit card firm on Monday.

To pay for their orders, customers can create an account and register their Visa cards through the McDelivery app.

When they place their orders through the app, payment will then be made through the cards.
