After a successful trial run, Mumbai’s BEST will now be introducing 100 per cent digital ticketing on buses with the ‘Tap In Tap Out’ service by using Chalo smart cards and a mobile app from April 20.

Under the service, a passenger, after boarding the bus, will have to tap his/her smartcard in front of the digital machine affixed near the entrance. A green tick mark will allow the passenger to board the bus. The fare will then be deducted from the passenger’s smartcard or the mobile app after he/she de-boards by taping out.
