Nearly 2,000 passengers bought QR tickets on the Namma Metro app and WhatsApp on Tuesday, the first day of the service.
Starting November 1, passengers do not have to wait in long queues at metro stations and scramble for change at the counter to buy single-journey tickets and recharge smartcards.
They can simply log onto the Namma Metro app or use the WhatsApp chatbot number (810 555 66 77) to do so. Payments can be made using Namma Metro or WhatsApp, and users will receive a 5 per cent discount on the token fare.
