After Prime Minister Narendra Modi launched the National Common Mobility Card in Delhi Metro earlier this week, the BEST, that is the next city transporter to implement it, is stuck in trial after trial. "The BEST has been a failure in technologies. They have experimented with a lot of ideas and technologies but have failed due to lack of interest and expertise," said a former official.

Once implemented, holders of the common mobility card will be able to commute on any BEST bus at any time. Pic/FILE
