New Delhi: The Delhi government is looking into using the Delhi Metro smart-card as a common transport card for metro, DTC and cluster buses. In a meeting held last week, the Delhi Metro Rail Corporation (DMRC) was asked to look into the feasibility of merging the Delhi Metro smart-card with the cluster and DTC bus system, so that a single card can be used on all modes of public transport. Incidentally, the same suggestion had been mooted during the Commonwealth Games but couldn’t take off due to differences over revenue sharing between the DMRC and the Delhi government.
