Many restaurants, particularly expensive ones have contactless ordering in place when you sit down for a meal. This is how it works:Download a scanning app like Google Lens or use the inbuilt code scanning app from your phone if you have one. You can pay online using your credit or debit card or a UPI app like Google Pay or Phone Pe. This gives you an interest free period of a month and credit card points on your purchase. Interest on credit card dues tends to be 35-40% per annum.
