Now, the traffic police can penalise traffic rules violators through smartphone by just taking pictures of the vehicles' number plate.

"The smartphone can automatically recognise the number plate. The police personnel will take pictures of vehicles violating the traffic rules. It will be sent to the traffic management centre's server, where an online bill will be generated," a senior traffic police said.

Eighty-eight new smartphones were distributed to the junction-level traffic constables on Monday.
