Yes. Earlier agents wud buy random tickets of different age groups.Then they wud just sell it to person seeking tickets at some commission.They inform the person abt the name and age which they have to tell to TC in case TC asks for name.TCs wud avoid asking for ID proof as there was no hard and fast rule for them to ask for ID card.Now with this rule, TC will ask for ID proof. And agents cant buy tickets without knowing ID no. in advance.
