Yes, you can still pay in cash for a Grab taxi or car ride in Singapore in 2026. While Grab encourages "cashless convenience" through their GrabPay wallet and linked credit or debit cards, the "Cash" option remains a standard feature in the app's payment menu. When you book a ride, you can tap the payment method at the bottom of the screen and select "Cash." This allows you to pay the driver directly at the end of the trip. Note that the fare shown in the app usually excludes tolls (ERP) and specific airport surcharges, which the driver will add to the final total. While cash is accepted for rides and food delivery, it is worth noting that for in-store QR code payments at merchants, you typically must use the GrabPay wallet balance. For international travelers, paying in cash is a reliable backup if your foreign credit card is not accepted by the app's billing system.
