Colour-coded passes to regulate entry to stations

A uniquely designed bot (web robot) will help keep the passenger count on Metro trains below 400 per rake every trip to maintain social distancing norms. The boarding pass on the mobile phone of a passenger will change its colour every hour. This colour code can easily be spotted by the cop at the entrance to the metro subway and help him allow passengers into the station according to the right time slot.
